-----------------------------------
Summary: Allow Dynamic Connection Pooling Service for ExecuteSQL
Key: NIFI-2973
URL: https://issues.apache.org/jira/browse/NIFI-2973
Project: Apache NiFi
Issue Type: Improvement
Components: Core Framework
Reporter: Sam Hjelmfelt
Currently, extracting data from multiple databases requires a RouteOnAttribute
processor and one ExecuteSQL processor for each database server. If the
"Database Connection Pooling Service" attribute could be set with EL, one
ExecuteSQL processor could be used.
In the ExecuteSQL processor, the connection is obtained in each OnTrigger
execution anyway:
172: final DBCPService dbcpService =
context.getProperty(DBCP_SERVICE).asControllerService(DBCPService.class);
...
192: final Connection con = dbcpService.getConnection();
