Andres de la Peña updated CASSANDRA-17194:
------------------------------------------
Description:
Migrate the existing thresholds for compaction:
{code:java}
compaction_large_partition_warning_threshold_mb: 100
compaction_tombstone_warning_threshold: 100000
{code}
To a new set of guardrails under the {{guardrails}} section, for example:
{code:java}
partition_size_warn_threshold: 50MiB
partition_size_fail_threshold: 100MiB
partition_tombstones_fail_threshold: 50000
partition_tombstones_fail_threshold: 100000
{code}
Note that since these guardrails would be attached to a background process
there wouldn't be abort/fail thresholds because we don't want to stop
compaction.
At the moment these thresholds are enabled by default, while guardrails are
globally disabled by default, so we should consider whether we want to globally
enable guardrails, or change these thresholds to disabled by default, or don't
migrate the thresholds.
