TopNRecords Processor
Top-N queries are queries that limit the result to a specific number of rows. These are often the queries for the “most recent” or the “best” entries of a result set.
For efficient execution, the ranking must be done with a pipelined order by. You can get Top-N records based on a sorting criterion.
Top N Records works with Batch Pipeline only.
