[jira] [Created] (CASSANDRA-16214) Improve Logging Downstream of DataOutputBuffer Overflows

Caleb Rackliffe created CASSANDRA-16214:
-------------------------------------------

             Summary: Improve Logging Downstream of DataOutputBuffer Overflows
                 Key: CASSANDRA-16214
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-16214
             Project: Cassandra
          Issue Type: Improvement
          Components: Observability/Logging
            Reporter: Caleb Rackliffe


There are a number of codepaths that buffer intermediate representations of a partition in memory in a {{DataOutputBuffer}}. Compactions and reads (involving multiple SSTables) can both produce partitions whose serialized size is larger than {{MAX_ARRAY_SIZE}}, in which case a {{RuntimeException}} and really not much else makes it to the logs. We should be able to improve this so that at least the offending keyspace, table, and partition are logged.
