> Add GenerateTableFetch processor
> --------------------------------
>
> Key: NIFI-2157
> URL: https://issues.apache.org/jira/browse/NIFI-2157
> Project: Apache NiFi
> Issue Type: Sub-task
> Reporter: Matt Burgess

> Fix For: 1.0.0

>
> This processor would presumably operate like QueryDatabaseTable, except it
> will contain a "Partition Size" property, and rather than executing the SQL
> statement(s) to fetch rows, it would generate flow files containing SQL
> statements that will select rows from a table. If the partition size is
> indicated, then the SELECT statements will refer to a range of rows, such
> that each statement will grab only a portion of the table. If max-value
> columns are specified, then only rows whose observed values for those columns
> exceed the current maximum will be fetched (i.e. like QueryDatabaseTable).
> These flow files (due to NIFI-1973) can be passed to ExecuteSQL processors
> for the actual fetching of rows, and ExecuteSQL can be distributed across
> cluster nodes and/or multiple tasks. These features enable distributed
> incremental fetching of rows from database table(s).
