About Tarantool Cartridge
Tarantool Cartridge allows you to easily develop Tarantool-based applications and run them on one or more Tarantool instances organized into a cluster.
This 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 an application template 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.
As a cluster management tool, Tarantool Cartridge provides your cluster-aware applications with the following key 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.
Tarantool Cartridge has an external utility called cartridge-cli which provides you with utilities and an application template to help:
- easily set up a development environment for your applications;
- plug the necessary Lua modules;
- pack the applications in an environment-independent way: together with module binaries and Tarantool executables.
Getting started
Prerequisites
To get a template application that uses Tarantool Cartridge and run it, you need to install several packages:
tarantool
andtarantool-dev
(see these instructions);cartridge-cli
(see these instructions)git
,gcc
,cmake
andmake
.
Create your first application
Long story short, enter these commands into the console one-by-one:
cartridge create --name myapp
cd myapp
cartridge build
cartridge start -d
cartridge replicasets setup --bootstrap-vshard
cartridge failover set stateful --state-provider stateboard --provider-params '{"uri": "localhost:4401", "password": "passwd"}'
That's all! Now you can visit http://localhost:8081 and see your application's Admin Web UI:
