[jira] [Created] (CASSANDRA-5706) OOM while loading key cache at startup

Fabien Rousseau created CASSANDRA-5706:
------------------------------------------

             Summary: OOM while loading key cache at startup
                 Key: CASSANDRA-5706
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5706
             Project: Cassandra
          Issue Type: Bug
    Affects Versions: 1.2.6
            Reporter: Fabien Rousseau
         Attachments: 5706-OOM-while-loading-key-cache-at-startup.patch

Steps to be able to reproduce it :
 - have a heap of 1Gb
 - have a saved key cache without the SSTables

When looking at KeyCacheSerializer.serialize : it always writes a Boolean
When looking at KeyCacheSerializer.deserialize : no Boolean is read if SSTable is missing...

In case of a promoted index, RowIndexEntry.serializer.skip(...) should be called rather than RowIndexEntry.serializer.skipPromotedIndex(...) (again for symmetry between serialization/deserialization)

Attached is a proposed patch
