CData Sync



Replicate multiple Elasticsearch accounts to one or many databases.

CData Sync for Elasticsearch is a stand-alone application that provides solutions for a variety of replication scenarios such as replicating sandbox and production instances into your database. Both Sync for Windows and Sync for Java include a command-line interface (CLI) that makes it easy to manage multiple Elasticsearch connections. In this article we show how to use the CLI to replicate multiple Elasticsearch accounts.

Configure Elasticsearch Connections

You can save connection and email notification settings in an XML configuration file. To replicate multiple Elasticsearch accounts, use multiple configuration files. Below is an example configuration to replicate Elasticsearch 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 Queries for Each Elasticsearch Instance

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 you want to use to update a particular database. Separate replication statements with semicolons. The following options are useful if you are replicating multiple Elasticsearch accounts into the same database:

You can use a different table prefix in the REPLICATE SELECT statement:

REPLICATE PROD_Orders SELECT * FROM Orders

Alternatively, you can use a different schema:

REPLICATE PROD.Orders SELECT * FROM Orders

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 MyProductionElasticsearchConfig.xml -f MyProductionElasticsearchSync.sql

Java

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