---------------------------------------------
Summary: Migrate thresholds for compaction to guardrails
Key: CASSANDRA-17194
URL: https://issues.apache.org/jira/browse/CASSANDRA-17194
Project: Cassandra
Issue Type: New Feature
Components: Feature/Guardrails
Reporter: Andres de la Peña
Migrate the existing thresholds for replica filtering protection:
{code:java}
compaction_large_partition_warning_threshold_mb: 100
compaction_tombstone_warning_threshold: 100000
{code}
To a new guardrail under the {{guardrails}} section, for example:
{code:java}
guardrails:
...
compacted_partition_size_warn_threshold_mb: 100
compacted_partition_tombstone_warn_threshold: 100000
{code}
Or maybe:
{code:java}
guardrails:
...
compacted_partition_size:
warn_threshold_mb: 100
compacted_partition_tombstones:
warn_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.
