What’s new in Tarantool 1.7?

The disk-based storage engine, which was called sophia or phia in earlier versions, is superseded by the vinyl storage engine.

There are new types for indexed fields.

The LuaJIT version is updated.

Automatic replica set bootstrap (for easier configuration of a new replica set) is supported.

The space_object:inc() function is removed.

The space_object:dec() function is removed.

The space_object:bsize() function is added.

The box.coredump() function is removed, for an alternative see Generating a core file.

The hot_standby configuration option is added.

Configuration parameters revised:

  • Parameters renamed:
    • slab_alloc_arena (in gigabytes) to memtx_memory (in bytes),
    • slab_alloc_minimal to memtx_min_tuple_size,
    • slab_alloc_maximal to memtx_max_tuple_size,
    • replication_source to replication,
    • snap_dir to memtx_dir,
    • logger to log,
    • logger_nonblock to log_nonblock,
    • snapshot_count to checkpoint_count,
    • snapshot_period to checkpoint_interval,
    • panic_on_wal_error and panic_on_snap_error united under force_recovery.
  • Until Tarantool 1.8, you can use deprecated parameters for both initial and runtime configuration, but Tarantool will display a warning. Also, you can specify both deprecated and up-to-date parameters, provided that their values are harmonized. If not, Tarantool will display an error.
