Replicate Redis Data to Multiple Databases
Replicate Redis data to disparate databases with a single configuration.
Always-on applications rely on automatic failover capabilities and real-time access to data. CData Sync for Redis integrates live Redis data into your mirrored databases, always-on cloud databases, and other databases such as your reporting server: Automatically synchronize with remote Redis data from Windows or any machine running Java.
You can use Sync's command-line interface (CLI) to easily control almost all aspects of the replication. You can use the CLI to replicate Redis data to one or many databases without any need to change your configuration.
Connect to Redis Data
You can save connection strings and other settings like email notifications in XML configuration files.
The following example shows how to replicate to SQLite.
Windows
<?xml version="1.0" encoding="UTF-8" ?>
<CDataSync><DatabaseType>SQLite</DatabaseType>
<DatabaseProvider>System.Data.SQLite</DatabaseProvider>
<ConnectionString>Server=127.0.0.1;Port=6379;Password=myPassword;</ConnectionString>
<ReplicateAll>False</ReplicateAll>
<NotificationUserName></NotificationUserName>
<DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
<TaskSchedulerStartTime>09:51</TaskSchedulerStartTime>
<TaskSchedulerInterval>Never</TaskSchedulerInterval>
</CDataSync>
Java
<?xml version="1.0" encoding="UTF-8" ?>
<CDataSync><DatabaseType>SQLite</DatabaseType><DatabaseProvider>org.sqlite.JDBC</DatabaseProvider>
<ConnectionString>Server=127.0.0.1;Port=6379;Password=myPassword;</ConnectionString>
<ReplicateAll>False</ReplicateAll>
<NotificationUserName></NotificationUserName>
<DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
</CDataSync>
Set the following connection properties to connect to a Redis instance:
- Server: Set this to the name or address of the server your Redis instance is running on. You can specify the port in Port.
- Password: Set this to the password used to authenticate with a password-protected Redis instance , using the Redis AUTH command.
Set UseSSL to negotiate SSL/TLS encryption when you connect.
Configure Replication Queries
Sync enables you to control replication with standard SQL. The REPLICATE statement is a high-level command that caches and maintains a table in your database. You can define any SELECT query supported by the Redis API. The statement below caches and incrementally updates a table of Redis data:
REPLICATE Customers;
You can specify a file containing the replication queries. This enables you to use the same replication queries to replicate to several databases.
Run Sync
After you have configured the connection strings and replication queries, you can run Sync with the following command-line options:
Windows
RedisSync.exe -g MySQLiteConfig.xml -f RedisSync.sql
Java
java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar RedisSync.jar -g MySQLiteConfig.xml -f RedisSync.sql
