Protected Static_StaticCoalesceWhen enabled, concurrent RunViews calls arriving within the same microtask (or within CoalesceWindowMs) are merged into a single mega-batch before hitting the network. This dramatically reduces the number of HTTP round-trips during startup when multiple engines independently call RunViews in parallel.
Set to 0 to disable coalescing. Default 10ms — enough to capture all engines that fire in the same tick, without adding perceptible delay.
StaticDedupHow long (ms) a resolved RunViews result stays available for instant replay. Set to 0 to disable the linger window (in-flight dedup still applies). Default 5 000 ms.
StaticMaxSafety cap on the number of linger entries held simultaneously. The linger window is a latency optimization — under extreme churn (more distinct query keys than this resolving within one window) new resolutions skip lingering instead of accumulating result arrays in memory.
StaticMinMinimum interval (ms) between metadata refresh checks to prevent redundant network calls when Config()/RefreshIfNeeded() fire in quick succession (e.g., multiple engines during startup). Does NOT affect forced Refresh() calls. Default: 30 000 ms.
StaticServerMaximum row count for auto-caching on the server side. When
TrustLocalCacheCompletely is true and a RunView result has no
ExtraFilter, no OrderBy, and the result count is at or below this
threshold, the result is automatically stored in LocalCacheManager
even without an explicit CacheLocal flag.
This captures small reference/lookup tables that are repeatedly queried by multiple clients while avoiding caching large ad-hoc result sets. Invalidation is handled by the standard BaseEntity event-driven upsert (safe because unfiltered caches can be updated in-place).
Set to 0 to disable auto-caching. Default 250.
Gets all explorer navigation items including inactive ones.
Array of all ExplorerNavigationItem objects
Returns the currently loaded local metadata from within the instance
Protected AbstractAllowDetermines if a refresh is currently allowed or not. Subclasses should return FALSE if they are performing operations that should prevent refreshes. This helps avoid metadata refreshes during critical operations.

AbstractDatabaseFor providers that have ProviderType==='Database', this property will return an object that represents the underlying database connection. For providers where ProviderType==='Network' this property will throw an exception. The type of object returned is provider-specific (e.g., SQL connection pool).
Gets all entity metadata in the system.
Array of EntityInfo objects representing all entities
Returns the filesystem provider for the current environment. Default implementation returns null (no filesystem access). Server-side providers should override this to return a NodeFileSystemProvider.
AbstractInstanceThis property is implemented by each sub-class of ProviderBase and is intended to return a unique string that identifies the instance of the provider for the connection it is making. For example: for network connections, the URL including a TCP port would be a good connection string, whereas on database connections the database host url/instance/port would be a good connection string. This is used as part of cache keys to ensure different connections don't share cached data.
Gets the latest metadata timestamps from local cache. Used for comparison with remote timestamps.
Array of locally cached metadata timestamps
Gets the latest metadata timestamps from the remote server. Used to determine if local cache is out of date.
Array of metadata timestamp information
Gets all library definitions in the system.
Array of LibraryInfo objects representing code libraries
ProtectedLocalThis property will return the prefix to use for local storage keys. This is useful if you have multiple instances of a provider running in the same environment and you want to keep their local storage keys separate. The default implementation returns an empty string, but subclasses can override this to return a unique string based on the connection or other distinct identifier.
AbstractLocalGets the local storage provider implementation. Must be implemented by subclasses to provide environment-specific storage.
Local storage provider instance
Protected AbstractMetadataGets the metadata provider instance. Must be implemented by subclasses to provide access to metadata.

ProtectedTrustWhen true, cached RunView/RunQuery results are returned immediately on a cache hit without any server-side validation round-trip.
Server-side providers (DatabaseProviderBase and its subclasses) override
this to return true because the cache is kept in perfect sync via
BaseEntity save/delete events and cross-server Redis pub/sub — the DB
validation query is unnecessary overhead.
Client-side providers (e.g. GraphQLDataProvider) keep the default false
so that the lightweight smart cache check (maxUpdatedAt + rowCount) is
still performed against the server before trusting the browser cache.
Gets only active explorer navigation items sorted by sequence. Results are cached for performance.
Array of active ExplorerNavigationItem objects
Background validation for the stale-while-revalidate fast-start pattern. Checks if local metadata is still current; if stale, fetches fresh metadata and atomically swaps it in. The app continues operating on cached data during this process — no blocking.
OptionalproviderToUse: IMetadataProviderProtectedBuildBuilds dataset filters based on the provider configuration. Ensures MJ Core schema is always included and never excluded.
Array of filters to apply when loading metadata
Stores a dataset in the local cache. If itemFilters are provided, the combination of datasetName and the filters are used to build a key and determine a match in the cache
ProtectedcacheSECURITY — decide whether the shared cache must be BYPASSED for a RunView that targets
a saved VIEW rather than a named entity (no EntityName), under a context user.
The cache-hit path returns BEFORE the DB provider's read-permission gate
(CheckUserReadPermissions). The primary gate keys off the entity resolved from
params.EntityName, so a ViewID-/ViewName-only request (the Explorer-standard shape for a
saved view) yields no entity there and the gate is disarmed — a read-denied user could be
served rows a permitted user warmed for the same ViewID. The vw: fingerprint segment makes
the two users' requests collide on exactly one slot, so the leak is clean.
Returns true when the cache must be skipped for this call (fail-closed):
ViewEntity supplied and its entity resolves → apply the normal CanRead gate on it
(allow caching for a permitted user; deny for a read-denied one).ViewEntity absent/unresolvable but ViewID/ViewName present → fail closed: the view's
real entity (hence the user's permission) is only known after the async MJ: User Views
lookup that the cache-hit path deliberately skips, so we cannot safely consult the cache.
Returns false when there is no context user, when EntityName is set (the normal gate owns
that path), or when no view identifier is present at all (nothing to gate).OptionalcontextUser: UserInfoChecks if local metadata is out of date and needs refreshing. Compares local timestamps with server timestamps.
OptionalproviderToUse: IMetadataProviderTrue if refresh is needed, false otherwise
If the specified datasetName is cached, this method will clear the cache. If itemFilters are provided, the combination of datasetName and the filters are used to determine a match in the cache
OptionalitemFilters: DatasetItemFilterType[]ProtectedCloneThe reuse-global fast path now builds a shared shell instead — see CreateSharedMetadataShell. The metadata graph is immutable after Config, so re-instantiating every Info object (~1s of synchronous constructor work for a ~600-entity install) bought no isolation the shell doesn't already provide. Subclass OVERRIDES of this method are still honored on the fast path (see CopyMetadataFromGlobalProvider) for backward compatibility; new customizations should override CreateSharedMetadataShell instead.
ProtectedComputeComputes the per-user Row-Level-Security WHERE clause that InternalRunView will append to this query's SQL for the given user, so it can be folded into the cache fingerprint. RLS-scoped reads return a different result set than unscoped reads of the same entity+filter; without including the RLS clause in the cache key, a scoped user could be served a cached unscoped result set (a data leak).
Returns '' when the user is exempt from RLS on this entity (the common case), which makes the resulting fingerprint byte-identical to the pre-RLS format — preserving normal cache sharing.
Uses this (the active provider) to resolve the entity, never the global Metadata, so the
correct per-provider/per-tenant metadata is consulted.
OptionalcontextUser: UserInfoConfigures the provider with the specified configuration data. Handles metadata refresh if needed and initializes the provider.
Configuration including schema filters and connection info
OptionalproviderToUse: IMetadataProviderTrue if configuration was successful
ProtectedConvertConverts dataset item filters into a unique string key for caching.
Array of filters to convert
JSON-formatted string representing the filters
ProtectedCopyAdopts the global provider's metadata for this instance without reloading it from the server: shares the (immutable post-Config) metadata arrays by reference via CreateSharedMetadataShell and builds this instance's entity lookup maps.
ProtectedCreateBuilds this instance's AllMetadata as a thin shell over another provider's already-loaded metadata: every metadata array is a PER-INSTANCE shallow copy whose elements are the SHARED Info object instances, and CurrentUser remains this instance's own.
Why sharing the instances is safe — and why this replaced the former deep clone (CloneAllMetadata) on the reuse-global fast path: the metadata graph is immutable after Config. Refreshes swap the WHOLE AllMetadata object (UpdateLocalMetadata), never mutate the Info objects in place, so the only per-instance datum inside the graph is CurrentUser — which this shell keeps independent. The deep clone cost ~1s of event-loop-blocking constructor work per provider on every server request (MemberJunction/MJ#3083); the shell is ~20 array-of-pointer copies (microseconds).
Why the array containers are copied rather than aliased: an in-place
.sort()/.push()/.splice() by request-scoped code then stays local to
that provider — matching the clone era's isolation for the common accidental
mutation class — instead of reordering the global graph for every other
in-flight request. Only the top-level AllMetadata collections get this
per-instance protection: everything below them is shared, including the
nested arrays owned by Info objects (entity.Fields,
entity.RelatedEntities, application.ApplicationEntities, ...) — an
in-place mutation of those is process-wide. Property writes on the shared
Info objects themselves are likewise visible process-wide (as they always
were on the client's global provider): treat Info objects and everything
they own as read-only; copy before sorting.
Override precedence: if a subclass overrides BOTH this method and the deprecated CloneAllMetadata, the CloneAllMetadata override wins on the fast path (see CopyMetadataFromGlobalProvider) — the conservative back-compat choice, since pre-#3083 subclasses could only have customized adoption through CloneAllMetadata. Remove the CloneAllMetadata override to activate a CreateSharedMetadataShell override.
AbstractCreateCreates a new transaction group for managing database transactions. Must be implemented by subclasses to provide transaction support.

ProtectedextractPerforms a full-text search across all entities that have FullTextSearchEnabled=true. Uses the existing RunView + UserSearchString infrastructure which routes through the database-native FTS capabilities (SQL Server FREETEXT functions, PostgreSQL tsvector).
This is the default implementation that works across all database providers. Each provider's createViewUserSearchSQL() method handles the platform-specific SQL generation.
OptionalcontextUser: UserInfoProtectedGetRetrieves all metadata from the server and constructs typed instances. Uses the MJ_Metadata dataset for efficient bulk loading.
OptionalproviderToUse: IMetadataProviderOptionalforceRefresh: booleanComplete metadata collection with all relationships

OptionalitemFilters: DatasetItemFilterType[]OptionalcontextUser: UserInfoOptionalproviderToUse: IMetadataProviderThis routine gets the local cached version of a given datasetName/itemFilters combination, it does NOT check the server status first and does not fall back on the server if there isn't a local cache version of this dataset/itemFilters combination

OptionalitemFilters: DatasetItemFilterType[]optional filters to apply to the dataset
AbstractGetReturns a list of dependencies - records that are linked to the specified Entity/RecordID combination. A dependency is as defined by the relationships in the database. The MemberJunction metadata that is used for this simply reflects the foreign key relationships that exist in the database. The CodeGen tool is what detects all of the relationships and generates the metadata that is used by MemberJunction. The metadata in question is within the EntityField table and specifically the RelatedEntity and RelatedEntityField columns. In turn, this method uses that metadata and queries the database to determine the dependencies. To get the list of entity dependencies you can use the utility method GetEntityDependencies(), which doesn't check for dependencies on a specific record, but rather gets the metadata in one shot that can be used for dependency checking.

ProtectedInternalProvider-specific transport for a Remote Operation. The default implementation reports that the provider does not support remote operations; concrete providers override it — server providers resolve and execute the operation in-process, the client provider marshals it over GraphQL.

Synchronous + non-throwing: resolves from cached metadata only.
ProtectedIsChecks whether server-side caching is allowed for the entity in the given RunViewParams. Returns false for entities that have TrustServerCacheCompletely = false, or for Record Changes which is always exempt (rows are created via raw SQL side-effects, not BaseEntity.Save(), so cache invalidation events never fire).

Synchronous pre-validation of cached metadata before engine startup.
On a warm load we serve the metadata graph from IndexedDB so the app can boot without pulling MBs of metadata from the server. Before engines run, this method makes one batched timestamp round-trip to confirm the snapshot is still current:
Cost on the warm-current path is one batched timestamp fetch (~50–200 ms depending on RTT). On the warm-stale path we additionally pay the full metadata fetch but avoid serving stale data to the UI in the first place.
Caller contract: invoke this before StartupManager.Startup().
OptionalproviderToUse: IMetadataProviderProtectedRebuildRebuilds the O(1) entity lookup Maps from the current AllEntities array. Called automatically from UpdateLocalMetadata().
Refreshes all metadata from the server. Respects the AllowRefresh flag from subclasses.

Refreshes metadata only if needed based on timestamp comparison. Combines check and refresh into a single operation.
OptionalproviderToUse: IMetadataProviderTrue if refresh was successful or not needed
Refreshes the remote metadata timestamps from the server. Updates the internal cache of remote timestamps.
OptionalproviderToUse: IMetadataProviderTrue if timestamps were successfully refreshed
Removes all cached metadata from local storage. Clears both timestamps and metadata collections.
ProtectedResolveResolves any PlatformSQL values in RunViewParams to plain strings for the active platform. Mutates the params object in place so downstream InternalRunView implementations always receive plain string values for ExtraFilter and OrderBy.
ProtectedResolveThe RunQuery cache-serve seam (B45/B46) — resolves a RunQuery request against this provider's query metadata and answers, in ONE computation performed BEFORE fingerprinting:
categoryPath: the RESOLVED query's canonical full category path. This becomes a
distinguishing fingerprint segment (B46) so two same-named queries in different
categories can never collide onto one cache slot. When the request is unresolvable the
caller falls back to the CALLER-STATED params.CategoryPath (still distinguishing,
just not canonicalized).resolvable: whether metadata could resolve the request at all. Runtime-created
queries are typically NOT resolvable from the base metadata cache (it does not refresh
in-process) — the gate then applies the warmer tie-break instead.authorized: whether user may run the resolved query. Meaningful only when
resolvable is true.The BASE implementation resolves from the metadata Queries cache and enforces the
ROLES-ONLY QueryInfo.UserCanRun — the strongest check available at this layer.
Providers with richer query metadata MUST override this to enforce the SAME authorization
their miss path enforces (GenericDatabaseProvider overrides with
MJQueryEntityExtended.UserCanRun, which adds entity CanRead + recursive composition
checks — the exact check ValidateQueryForExecution applies on a cache miss). The
invariant this seam exists to hold: a cache HIT must never be easier to read than a
cache MISS (B45 was precisely that asymmetry — the TTL gate checked roles only while
the miss path also checked entity read permissions).
Optionaluser: UserInfoResolves a PlatformSQL value to the appropriate SQL string for this provider's platform. If the value is a plain string, it is returned as-is (backward compatible). If the value is a PlatformSQL object, the platform-specific variant is used if available, otherwise the default variant is used.

ProtectedRunRuns all registered PostRunView hooks against a single result, returning the (possibly mutated) result.
Protected (not private) for the same reason as RunPreRunViewHooks above: a subclass pipeline that returns view rows WITHOUT passing through PostRunView/PostRunViews — e.g. the RunViewsWithCacheCheck smart-cache path — MUST apply these hooks to the rows it returns. PostRunView is the OUTPUT half of the enforcement seam (data masking / audit); a path that skips it returns rows the hooked paths would have masked.
OptionalcontextUser: UserInfoProtectedRunRuns all registered PreRunView hooks against a single RunViewParams, returning the (possibly mutated) params.
Protected (not private) on purpose: any subclass pipeline that executes view queries WITHOUT passing through PreRunView/PreRunViews — e.g. the RunViewsWithCacheCheck smart-cache path in GenericDatabaseProvider — MUST apply these hooks itself. Hooks are an enforcement seam (tenant scoping middleware injects filters here); a query path that skips them silently returns rows the hooked paths would have filtered out.

The view results
ProtectedrunSingle source of truth for whether a RunView call participates in the local cache (both READ and WRITE). Pre/Post hooks for the singular and batch paths must all use this predicate — historically each site recomputed it inline and they drifted (PostRunViews wrote BypassCache results into the cache, poisoning the Fields-agnostic superset slot with narrow rows).
Ineligible:
BypassCache — caller explicitly wants true DB state, no cache interactionAfterKey — keyset pages are single-use AND the fingerprint doesn't include
the seek key, so caching a page would poison the entity+filter slotResultType 'count_only' — returns no rows; caching its empty Results under
a fingerprint that excludes ResultType would poison row queriesRuns multiple views based on the provided parameters. Wraps the execution pipeline with request deduplication and a linger window so that concurrent (and near-sequential) identical calls share a single server round-trip. Every caller receives a shallow-copied Results array to protect against cross-caller mutations (push/sort/splice).

Saves current metadata to local storage for caching. Serializes both timestamps and full metadata collections.
Batch form of SearchEntity. Fans the input list out to N
independent SearchEntity calls via Promise.all; result arrays come
back aligned by input order (result[i] holds the matches for params[i]).
On the server side, the per-entity passes are independent — running them
concurrently is a real wall-clock win when the caller wants results from
multiple entities. On the client side, GraphQLDataProvider overrides
this method to pack the whole batch into a single GraphQL round-trip
instead of issuing N parallel HTTP requests.
See IMetadataProvider.SearchEntities for the contract.
Protected AbstractsearchRun the semantic ranking pass for SearchEntity. Each concrete
ProviderBase subclass supplies its own implementation: server-side
providers (GenericDatabaseProvider) embed the query text and query
an in-process vector pool directly; client-side providers
(GraphQLDataProvider) override SearchEntity / SearchEntities
outright to proxy via GraphQL and never reach this method.
Ranked array of ScoredCandidate whose ID is the parent
entity's record ID and Metadata.entityRecordDocumentId
carries the EntityRecordDocument PK.
Ranked search over one entity's records. See IMetadataProvider.SearchEntity for the contract and how this differs from EntityByName / FullTextSearch.

ProtectedUpdateUpdates the local metadata cache with new data.

Protected StaticarrayConverts an ArrayBuffer to a base64-encoded string. Used for compressed metadata storage/retrieval.
Protected Staticbase64Converts a base64-encoded string to an ArrayBuffer. Used for compressed metadata storage/retrieval.
Protected StaticUnionReturns the caller's requested fields (lowercased) unioned with the entity's
primary key field names. Platform contract: when Fields is explicitly
specified, results ALWAYS include the primary key(s) — the direct SQL path has
always done this, differential smart-cache merges require it, and entity
linking in UIs depends on it. Applying the same union at every projection site
keeps result shapes identical across cached, non-cached, and smart-cache paths.
Base class for all metadata providers in MemberJunction. Implements common functionality for metadata caching, refresh, and dataset management. Subclasses must implement abstract methods for provider-specific operations.
