ReQL command: status

Command syntax

table.status() → selection<object>

Description

Return the status of a table.

The return value is an object providing information about the table’s shards, replicas and replica readiness states. For a more complete discussion of the object fields, read about the table_status table in System tables.

  • id: the UUID of the table.
  • name: the table’s name.
  • db: the database the table is in.
  • status: the subfields in this field indicate whether all shards of the table are ready to accept the given type of query: outdated_reads, reads and writes. The all_replicas_ready field indicates whether all backfills have finished.
  • shards: one entry for each shard in table_config. Each shard’s object has the following fields:
    • primary_replicas: a list of zero or more servers acting as primary replicas for the table.
    • replicas: a list of all servers acting as a replica for that shard. The state field may be one of the following: ready, transitioning, backfilling, disconnected, waiting_for_primary, or waiting_for_quorum.

Example: Get a table’s status.

> r.table('superheroes').status().run(conn, callback);
