Configuration

Use the canonical exported schema or inject compatible table objects:

const memory = new DrizzleMemoryStore({
  db,
  schema: drizzleMemorySchema,
  lock: 'advisory',
  errorPolicy: 'store',
  validateMessages: true,
  scopeKey: {
    includeUserId: true,
    metadataKeys: ['tenantId'],
  },
})

The schema object must provide agentMemorySessions, agentMemoryMessages, and agentMemoryErrors with the columns expected by the adapter. lock defaults to advisory, which requires db.execute and throws TypeError when it is missing; 'none' opts out of the advisory lock.

The database object must provide the Drizzle query and insert/delete methods in the public DrizzleDatabaseLike contract, including transaction; the constructor throws TypeError without it. Connection pooling and shutdown remain owned by the application.
