             Summary: Guardrail for partition size
                 Key: CASSANDRA-17152
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-17152
             Project: Cassandra
          Issue Type: New Feature
          Components: Feature/Guardrails
            Reporter: Andres de la Peña


Add a guardrail for large partitions. Finding the size of a partition is tricky because partitions can be spread over multiple sstable and we want to avoid read before write. Thus, this might be just a warning thrown during compaction and not be linked to specific user queries, for example:
{code}
# Log a warning when compacting partitions larger than this value.
# Defaults to -1 to disable
# partition_size_warn_threshold_in_mb: -1
{code}
