ETL modules can access data through a remote connection to an alternate LabKey Server.
To set up a remote connection, see
Manage Remote Connections.
To configure an ETL process to utilize a remote connection, specify the transform
type and the
remoteSource as shown below:
<transform type="RemoteQueryTransformStep" id="step1">
<source remoteSource="EtlTest_RemoteConnection" schemaName="study" queryName="etl source" />
...
</transform>
A sample ETL configuration file is shown below:
<?xml version="1.0" encoding="UTF-8"?>
<etl xmlns="http://labkey.org/etl/xml">
<name>Remote Test</name>
<description>append rows from "remote" etl_source to etl_target</description>
<transforms>
<transform type="RemoteQueryTransformStep" id="step1">
<description>Copy to target</description>
<source remoteSource="EtlTest_RemoteConnection" schemaName="study" queryName="etl source" />
<destination schemaName="study" queryName="etl target" targetOption="truncate"/>
</transform>
</transforms>
<incrementalFilter className="ModifiedSinceFilterStrategy" timestampColumnName="modified" />
</etl>
