Jakob Homan created SAMZA-82:
--------------------------------
Summary: Not use maximum number of partitions when initializing
streams
Key: SAMZA-82
URL: https://issues.apache.org/jira/browse/SAMZA-82
Project: Samza
Issue Type: Bug
Components: kafka
Affects Versions: 0.7.0
Reporter: Jakob Homan
Assignee: Jakob Homan
Fix For: 0.7.0
Util.scala:
{code} /**
* Uses config to create SystemAdmin classes for all input stream systems to
* get each input stream's partition count, then returns the maximum count.
* An input stream with two partitions, and a second input stream with four
* partitions would result in this method returning 4.
*/
def getMaxInputStreamPartitions(config: Config) = {
{code}
This approach works if all the streams have the same number of partitions, but
is inefficient for other cases and, where the underlying system gets cranky
about being asked about non-existing partitions, fails. We should eagerly
figure out the correct number of partitions for each topic and pass that
information from there.
