Connectors Python


tarantool-python is the official Python connector for Tarantool. It is not supplied as part of the Tarantool repository and must be installed separately (see below for details).

Here is a complete Python program that inserts [99999,'Value','Value'] into space examples via the high-level Python API.

from tarantool import Connection

c = Connection("", 3301)
result = c.insert("examples",(99999,'Value', 'Value'))
print result

To prepare, paste the code into a file named and install the tarantool-python connector with either pip install tarantool>0.4 to install in /usr (requires root privilege) or pip install tarantool>0.4 --user to install in ~ i.e. user’s default directory.

Before trying to run, check that the server instance is listening at localhost:3301 and that the space examples exists, as described earlier. To run the program, say python The program will connect to the Tarantool server, will send the INSERT request, and will not throw any exception if all went well. If the tuple already exists, the program will throw tarantool.error.DatabaseError: (3, "Duplicate key exists in unique index 'primary' in space 'examples'").

The example program only shows one request and does not show all that’s necessary for good practice. For that, please see tarantool-python project at GitHub.

Also there are several community-driven Python connectors:

The table below contains a feature comparison for asynctnt and tarantool-python. aiotarantool and gtarantool are absent there because they are quite outdated and unmaintained.
