-----------------------------------
Summary: Add thread-safe KuduPartitioner::PartitionRow() method
Key: KUDU-3139
URL: https://issues.apache.org/jira/browse/KUDU-3139
Project: Kudu
Issue Type: Improvement
Components: client
Reporter: Tim Armstrong
We have a scenario in IMPALA-9782 where we'd like to have multiple threads use
KuduPartitioner, but this currently requires instantiating many instances,
which is somewhat expensive. It would be a good improvement if we could share
the KuduPartitioner. This currently doesn't work because PartitionRow()
internally uses a buffer that's a member of the object -
https://github.com/cloudera/kudu/blob/master/src/kudu/client/partitioner-internal.cc#L40
I talked with [~aserbin] on slack and he suggested that adding a new method
that is not stateful would be a good way to solve this (I also considered
cloning KuduPartitioner).
