Cassandra Missing Default TTL Growth Guard
Flag Cassandra base tables stuck at default_time_to_live = 0 in keyspaces meant to expire data, alert Slack, then optionally set a bounded default TTL with ALTER TABLE and verify the schema.

Flag Cassandra base tables stuck at default_time_to_live = 0 in keyspaces meant to expire data, alert Slack, then optionally set a bounded default TTL with ALTER TABLE and verify the schema.
Query Cassandra's system_schema.keyspaces on a schedule, flag any keyspace still using SimpleStrategy replication, and alert Slack when the cluster is unsafely replicated or unreachable.
Flag Cassandra tables whose caching option sets rows_per_partition to ALL or above a ceiling, alert Slack, then rewrite it with ALTER TABLE behind an approval and re-read the schema.
Audit Apache Cassandra table speculative retry policies, pause for operator approval, mitigate read retry storms with safe CQL alterations, and verify alignment.
Audit Cassandra's system_auth.roles for superuser roles with login enabled, alert Slack on exposure, and optionally revoke login with ALTER ROLE.
Flag Cassandra base tables stored uncompressed, alert Slack, then turn on LZ4 compression with ALTER TABLE behind an approval and re-read the schema.
Monitor Cassandra 4.0+ virtual tables on schedule, detect saturated thread pools with blocked or pending tasks, and alert Slack.
Extract Cassandra data with CQL, serialize it to CSV, and load it into Google BigQuery for analytics.
Flag Cassandra tables whose compaction tombstone_threshold is too high to purge tombstones while unchecked_tombstone_compaction is off, alert Slack, then tune both subproperties with ALTER TABLE behind an approval while keeping the compaction class and re-read the schema.
Geocode a CSV of US addresses to longitude, latitude and state, county, tract and block FIPS codes with the free Census Geocoder batch endpoint, one multipart POST per run, and keep every answer in a Parquet cache so re-runs only send the addresses not seen before.
Fetch the Ceph Dashboard's own full health report and alert Slack on HEALTH_WARN or HEALTH_ERR, read-only.
List Ceph pools, alert Slack on any replicated pool below a minimum replica size, and optionally raise it back up.
List an RBD image's snapshots via the Ceph Dashboard API and alert Slack on any that are not protected, read-only.
Reverse, de-duplicate newest-wins, filter tombstones, split into partitions processed by a worker subflow, then reassemble a clean file and a rejects file. No script, only core storage tasks.
Score each change request on service criticality, blast radius, size, backout plan, testing and the team's failure rate, catch freeze windows and colliding changes, and route it to pre-approval, peer review or the CAB.
Build a RAG chat-with-your-data flow that retrieves answers from Elasticsearch and generates grounded responses with OpenAI.
Audits Chroma collections to validate HNSW distance metrics and prevent RAG retrieval corruption.
Keep a Chroma collection in sync with a Markdown docs repository, embedding only changed sections locally with FastEmbed, deleting stale chunks, and failing the run if retrieval regresses.
Automated ChromaDB collection preflight validation, paginated vector extraction to Parquet, and AWS S3 disaster recovery backup.
Audit Chroma vector collections for tombstoned and dangling embeddings, archive quarantined documents to KV, safely evict stale vectors with human approval, and verify post-deletion state.
