[jira] [Created] (APEXCORE-332) Support Even Distribution Of Tuples
To A Non Power Of 2 Number Of Partitions
Timothy Farkas created APEXCORE-332:
---------------------------------------
Summary: Support Even Distribution Of Tuples To A Non Power Of 2 Number Of Partitions
Key: APEXCORE-332
URL: https://issues.apache.org/jira/browse/APEXCORE-332
Project: Apache Apex Core
Issue Type: Improvement
Reporter: Timothy Farkas
Priority: Minor
Currently partitions masks must be defined as a binary mask. As a result the number of partitions must be a power of 2, otherwise the distribution of tuples will be uneven. If we support the modulus operation instead of a binary mask, we could support an even distribution of tuples to a non-power of 2 number of partitions.
