#DbCacheProvider

#Import

typescript 
1import { DbCacheProvider } from "alepha/orm";

#Overview

Database query cache using a simple in-memory Map.

Uses {tableName}:{cacheKey} as the storage key. Provides per-table invalidation for write-through cache busting.

This is intentionally self-contained (no external cache dependencies) so the ORM module does not force AlephaCache on all consumers.

#Bounded on purpose

The key space is not: it is derived from the caller's query, so a query built from user-controlled pagination or filter values mints a fresh entry per distinct input. expiresAt was only ever consulted inside get(), so an entry written once and never read again was reclaimed by nothing short of a write to its table — never, for a read-mostly table. Two bounds close that: expired entries are swept on write, and the map is capped at {@link MAX_ENTRIES} with oldest-first eviction (insertion order).
