Get the Report →Replicate GraphQL Data to Multiple Databases
Replicate GraphQL 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 GraphQL integrates live GraphQL data into your mirrored databases, always-on cloud databases, and other databases such as your reporting server: Automatically synchronize with remote GraphQL 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 GraphQL data to one or many databases without any need to change your configuration.
Connect to GraphQL 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>AuthScheme=Basic;User=username;Password=password;URL=https://mysite.com;</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>AuthScheme=Basic;User=username;Password=password;URL=https://mysite.com;</ConnectionString>
<ReplicateAll>False</ReplicateAll>
<NotificationUserName></NotificationUserName>
<DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
</CDataSync>
You must specify the URL of the GraphQL service. The driver supports two types of authentication:
- Basic: Set AuthScheme to Basic. You must specify the User and Password of the GraphQL service.
- OAuth 1.0 & 2.0: Take a look at the OAuth section in the Help documentation for detailed instructions.
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 GraphQL API. The statement below caches and incrementally updates a table of GraphQL data:
REPLICATE Users;
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
GraphQLSync.exe -g MySQLiteConfig.xml -f GraphQLSync.sql
Java
java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar GraphQLSync.jar -g MySQLiteConfig.xml -f GraphQLSync.sql
