Replicate Multiple SpaceX Accounts via the CData Sync CLI

CData Sync for SpaceX 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 SpaceX connections. In this article we show how to use the CLI to replicate multiple SpaceX accounts.

Configure SpaceX Connections

You can save connection and email notification settings in an XML configuration file. To replicate multiple SpaceX accounts, use multiple configuration files. Below is an example configuration to replicate SpaceX to SQLite:

Windows

<?xml version="1.0" encoding="UTF-8" ?>
<CDataSync>
 <DatabaseType>SQLite</DatabaseType>
 <DatabaseProvider>System.Data.SQLite</DatabaseProvider>
 <ConnectionString>Profile=C:\profiles\SpaceX.apip;</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>Profile=C:\profiles\SpaceX.apip;</ConnectionString>
 <ReplicateAll>False</ReplicateAll>
 <NotificationUserName></NotificationUserName>
 <DatabaseConnectionString>Data Source=C:\my.db</DatabaseConnectionString>
</CDataSync>

Set the ProfileSettings connection property to the connection string for SpaceX (see below).

SpaceX API Profile Settings

No authentication is required to access SpaceX data — the SpaceX API is publicly available. Simply set the Profile connection property to the path of the SpaceX profile file.

Configure Queries for Each SpaceX 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 SpaceX API. The statement below caches and incrementally updates a table of SpaceX data:

REPLICATE Capsules;

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 SpaceX accounts into the same database:

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

REPLICATE PROD_Capsules SELECT * FROM Capsules 

Alternatively, you can use a different schema:

REPLICATE PROD.Capsules SELECT * FROM Capsules

Run Sync

After you have configured the connection strings and replication queries, you can run Sync with the following command-line options:

Windows

APISync.exe -g MyProductionAPIConfig.xml -f MyProductionAPISync.sql

Java

java -Xbootclasspath/p:c:\sqlitejdbc.jar -jar APISync.jar -g MyProductionAPIConfig.xml -f MyProductionAPISync.sql
