Matt Burgess updated NIFI-4522:
-------------------------------
Status: Patch Available (was: In Progress)
> Add "SQL Statement" property to PutSQL
> --------------------------------------
>
> Key: NIFI-4522
> URL: https://issues.apache.org/jira/browse/NIFI-4522
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Extensions
> Reporter: Matt Burgess
> Assignee: Matt Burgess
>
> Currently the PutSQL processor expects the SQL statement to be executed to be
> in the contents of the incoming flow file(s). However there is a use case
> from a Simple Event Processing perspective; when you have a flowfile whose
> contents you want to keep, but because that flow file came through
> (presumably with some attributes of interest), you want to issue a SQL
> statement (perhaps to update an external DB with some status/metrics info).
> Adding a non-required, expression-language-supported, default-empty property
> called SQL Statement would allow both use cases; it preserves existing
> behavior by default, but provides the ability to issue an external command
> while retaining the current flow file contents.
