To ensure that the connection to the data source is successful, click the Test Connection link. To delete a password, right-click the Password field and select Set Empty. Alternatively, paste the JDBC URL in the URL field. From the Connection type list, select default. For more information about creating a database connection with your driver, see Add a user driver to an existing connection.Ĭurrently, only connection to a Single Redis Instance is supported. You can specify your drivers for the data source if you do not want to download the provided drivers. The IDE does not include bundled drivers in order to have a smaller size of the installation package and to keep driver versions up-to-date for each IDE version. ![]() As you click this link, DataGrip downloads drivers that are required to interact with a database. On the Data Sources tab in the Data Sources and Drivers dialog, click the Add icon ( ) and select Redis.Ĭheck if there is a Download missing driver files link at the bottom of the data source settings area. In the Database Explorer ( View | Tool Windows | Database Explorer), click the Data Source Properties icon. You can open data source properties by using one of the following options: Only after that you will see the DataGrip interface and will be able to create connections. If the client connects to another replica node in the same or different shard, then you might need to issue a new readonly command.You need to create and open a project from the Welcome Screen. The command is active only until the client reads keys from the same node. The readonly command needs to be issued when the client connects to a node for the first time. In the following example, the readonly command is sent first, so the replica node processes the request instead of redirecting it to a primary node. ![]() For more information about the MOVED error, refer to Redis cluster specification - Redirection and resharding on the Redis.io website. Note: The MOVED error shown in the preceding example occurs when the Redis cluster client isn't cluster aware and can't handle redirection requests to the primary node. In the following example, the readonly command isn't sent, and the request is redirected to a primary node. Otherwise, the request is redirected to the primary node of the shard that the hash slot belongs to.ġ. This means that the replica node processes the request only if readonly is issued by the client before the request. ![]() The replica node serves the read request only if that shard belongs to the hash slot and a readonly command is initiated by the client. ![]() The default behavior of replica nodes in cluster-mode enabled clusters is to redirect all client read/write requests to an authoritative primary node of the shard that belongs to the key's hash slot. When a client sends a read/write query to a replica node, the node analyzes the request to confirm whether it is a single key or multi-key operation that belongs to the same hash slot of the shard. Any node in a Redis cluster can receive queries from Redis clients.
