# Lock Stores

Rasa uses a ticket lock mechanism to ensure that incoming messages for a given conversation ID are processed in the right order, and locks conversations while messages are actively processed.

## InMemoryLockStore (default)

### Description

`InMemoryLockStore` is the default lock store. It maintains conversation locks within a single process.

### Note

This lock store should not be used when multiple Rasa servers are run parallel.

### Configuration

To use the `InMemoryTrackerStore` no configuration is needed.

## RedisLockStore

### Description

`RedisLockStore` maintains conversation locks using Redis as a persistence layer. This is the recommended lock store for running a replicated set of Rasa servers.

### Configuration

To set up Rasa with Redis the following steps are required:

1. Start your Redis instance

2. Add required configuration to your `endpoints.yml`

```
   lock_store:
       type: "redis"
       url: <url of the redis instance, e.g. localhost>
       port: <port of your redis instance, usually 6379>
       password: <password used for authentication>
       db: <number of your database within redis, e.g. 0>
   ```

3. To start the Rasa Core server using your Redis backend, add the `--endpoints` flag, e.g.:
   
   ```
   rasa run -m models --endpoints endpoints.yml
   ```

### Parameters

- `url` (default: `localhost`): The url of your redis instance
- `port` (default: `6379`): The port which redis is running on
- `db` (default: `0`): The number of your redis database
- `password` (default: `None`): Password used for authentication (`None` equals no authentication)
- `use_ssl` (default: `False`): Whether or not the communication is encrypted
