Function allByLookupKey

allByLookupKey<T = Record<string, unknown>>(
    lookupKey: string,
    sql: string,
    bindings?: any[],
    batchSize?: number,
): Promise<QueryResult<T>>
Retrieves all records using a secondary lookup key when available.

This helper attempts to resolve the lookup key through KV first. If a mapping exists, the query executes on that shard directly. If the mapping is missing, stale, or returns no rows, the helper safely falls back to fanout (allAllShards) and returns merged results.
Type Parameters
- T = Record<string, unknown>
  Type of the result records
Parameters
- lookupKey: string
  Secondary key such as email:user@example.com or username:alice
- sql: string
  SQL statement to execute
- bindings: any[] = []
  Parameter values to bind to the SQL statement
- batchSize: number = 50
  Number of concurrent shard queries during fanout (default: 50)
Returns Promise<QueryResult<T>>
Promise resolving to merged query results
