• MessagePack data format and MessagePack-based client-server protocol

• Two data engines:

  • memtx – in-memory storage engine with optional persistence
  • vinyl – on-disk storage engine to use with larger data sets

• Secondary key and index iterator support (can be non-unique and composite)

• Multiple index types: HASH, BITSET, TREE, RTREE

NOTE ^^^^

This driver is synchronous, so connection mustn't be shared between threads/processes.

If you're looking for an asynchronous Python driver based on asyncio, consider using asynctnt_ . See also the feature comparison table_.

• (On remote) Copy test/suites/lib/tarantool_python_ci.lua to /etc/tarantool/instances.available.
• (On remote) Run tarantoolctl start tarantool_python_ci.
• Set the following environment variables:
  • REMOTE_TARANTOOL_HOST=...,
  • REMOTE_TARANTOOL_CONSOLE_PORT=3302.
