[jira] [Created] (HBASE-7239) Verify protobuf serialization is
correctly chunking upon read to avoid direct memory OOMs
Lars Hofhansl created HBASE-7239:
------------------------------------
Summary: Verify protobuf serialization is correctly chunking upon read to avoid direct memory OOMs
Key: HBASE-7239
URL: https://issues.apache.org/jira/browse/HBASE-7239
Project: HBase
Issue Type: Sub-task
Reporter: Lars Hofhansl
Result.readFields() used to read from the input stream in 8k chunks to avoid OOM issues with direct memory.
(Reading variable sized chunks into direct memory prevent the JVM from reusing the allocated direct memory and direct memory is only collected during full GCs)
This is just to verify protobufs parseFrom type methods do the right thing as well so that we do not reintroduce this problem.
