Refactor: Extract entity state management into EntitiesState module - #1291
Merged
Conversation
Move currentlyProcessingBatch (renamed isProcessing) and the processedBatches counter (renamed processedBatchesCount) out of the versioned GlobalState record into the mutable InMemoryStore. Both were already updated identically in the valid and invalidated reducer paths, so they never relied on snapshot semantics; mutating them in place is behavior-preserving and drops a record spread plus a duplicated reducer update.
The module held only an Entity submodule and was always referenced as InMemoryTable.Entity. Flatten it into a top-level EntitiesState module so the type reads EntitiesState.t.

241-250: 💤 Low valueConsider clarifying the behavior when indexed entity is missing from the latest changes.
Lines 244-249 silently filter out entities that are in the index's
relatedEntityIdsbut not found inlatestEntityChangeById. This could mask state inconsistencies where an entity was indexed but later removed from the store without proper index cleanup.If this silent filtering is intentional (e.g., to handle race conditions gracefully), a brief comment explaining why would help future maintainers. If it's not intentional, consider logging a warning when an indexed entity is unexpectedly missing.

In `@packages/envio/src/EntitiesState.res`:
- Around line 210-214: getUnsafe currently passes Dict.getUnsafe's
possibly-undefined result straight into mapChangeToEntity causing undefined to
be treated as a Change; update getUnsafe to first check Dict.getUnsafe(key) for
undefined and return None (outer option) when missing, otherwise call
mapChangeToEntity on the found Change.t<Internal.entity> and return Some(mapped)
so the function correctly yields option<option<Internal.entity>>; locate this
logic in getUnsafe using inMemTable.latestEntityChangeById, Dict.getUnsafe and
mapChangeToEntity and implement the explicit missing-key branch.

This reverts commit cc5fffa.
isProcessing now lives in the mutable InMemoryStore, so the action was a vestigial state transition: it only flipped the store flag and returned the state unchanged. It is dispatched synchronously before any await in the ProcessEventBatch task, after the task already passed the stateId validity check, so it could never be routed to the invalidated reducer. Replace the dispatch with a direct mutation.

Summary
Extracted entity state management logic from the nested
InMemoryTable.Entitymodule into a top-levelEntitiesStatemodule. This improves code organization and makes the entity state management API more discoverable and testable.Key Changes
EntitiesState.resmodule containing all entity state management logic previously nested inInMemoryTable.EntityInMemoryTable.resmodule (theEntitysubmodule was its only content)EntitiesStateinstead ofInMemoryTable.EntityisProcessing,processedBatchesCount) fromGlobalStatetoInMemoryStorefor better encapsulationImplementation Details
EntitiesStatemodule maintains the same type definitions and function signatures as beforehttps://claude.ai/code/session_01HLTnM6hD6Qgy6aC1zBbsdJ
