About Tarantool Cartridge

Tarantool Cartridge is the recommended alternative to the old-school practices of application development for Tarantool.

As a software development kit (SDK), Tarantool Cartridge provides you with utilities and templates to help:

  • easily set up a development environment for your applications;
  • plug the necessary Lua modules.

The resulting package can be installed and started on one or multiple servers as one or multiple instantiated services – independent or organized into a cluster.


A Tarantool cluster is a collection of Tarantool instances acting in concert. While a single Tarantool instance can leverage the performance of a single server and is vulnerable to failure, the cluster spans multiple servers, utilizes their cumulative CPU power, and is fault-tolerant.

To fully utilize the capabilities of a Tarantool cluster, you need to develop applications keeping in mind they are to run in a cluster environment.

Further on, Tarantool Cartridge provides your cluster-aware applications with the following benefits:

  • horizontal scalability and load balancing via built-in automatic sharding;
  • asynchronous replication;
  • automatic failover;
  • centralized cluster control via GUI or API;
  • automatic configuration synchronization;
  • instance functionality segregation.

A Tarantool Cartridge cluster can segregate functionality between instances via built-in and custom (user-defined) cluster roles. You can toggle instances on and off on the fly during cluster operation. This allows you to put different types of workloads (e.g., compute- and transaction-intensive ones) on different physical servers with dedicated hardware.
