Description

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:

# Log a warning when compacting partitions larger than this value.
# Defaults to -1 to disable
# partition_size_warn_threshold_in_mb: -1
