CData Sync



Replicate Elasticsearch 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 Elasticsearch integrates live Elasticsearch data into your mirrored databases, always-on cloud databases, and other databases such as your reporting server: Automatically synchronize with remote Elasticsearch 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 Elasticsearch data to one or many databases without any need to change your configuration.

Connect to Elasticsearch 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=9200;User=admin;Password=123456;</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=9200;User=admin;Password=123456;</ConnectionString> <ReplicateAll>False</ReplicateAll> <NotificationUserName></NotificationUserName> <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString> </CDataSync>

Set the Server and Port connection properties to connect. To authenticate, set the User and Password properties, PKI (public key infrastructure) properties, or both. To use PKI, set the SSLClientCert, SSLClientCertType, SSLClientCertSubject, and SSLClientCertPassword properties.

The data provider uses X-Pack Security for TLS/SSL and authentication. To connect over TLS/SSL, prefix the Server value with 'https://'. Note: TLS/SSL and client authentication must be enabled on X-Pack to use PKI.

Once the data provider is connected, X-Pack will then perform user authentication and grant role permissions based on the realms you have configured.

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 Elasticsearch API. The statement below caches and incrementally updates a table of Elasticsearch data:

REPLICATE Orders;

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

ElasticsearchSync.exe -g MySQLiteConfig.xml -f ElasticsearchSync.sql

Java

java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar ElasticsearchSync.jar -g MySQLiteConfig.xml -f ElasticsearchSync.sql
