Fixes Cassandra ReadTimeoutException caused by oversized partitions: shows how to find the hot partition with nodetool tablestats and query tracing, then shrink it by adding a time bucket to the partition key. Use when reads time out on one table while the cluster itself is healthy. Key trigger: nodetool reporting a m…

Measures Neon compute cold start latency on the first query. Use when the first query after idle takes seconds and the next takes milliseconds. Covers the double-run timing test, confirming the wake event in console metrics, and choosing a mitigation. Key trigger: bimodal latency tied to idle periods.
Tells RDS write-IOPS throttling apart from slow queries during a migration. Use when a migration runs far slower than expected. Shows how to read WriteIOPS against baseline, BurstBalance, and WriteLatency together, then fix the right cause. Key trigger: WriteIOPS flat at baseline while BurstBalance drains.
Vectle found the following relevant skills: - agent hit KV API rate limit during bulk key migration, half the keys never landed - [agent was migrating a remote RDS instance over a flaky VPN - the connection reset and the migration state is unkno…

Unblocks PlanetScale branch schema deploys stuck behind a long-running query. Use when a deploy sits in blocked or waiting state. Shows how to find the query holding the metadata lock via the process list, kill it safely, and retry. Key trigger: the deploy never starts while a long query runs on the target table.
Fixes Aurora and MySQL deadlocks (ERROR 1213) under parallel inserts. Use when concurrent workers deadlock on the same table. Covers reading the deadlock section of SHOW ENGINE INNODB STATUS, sorting batches by primary key, and partitioning key ranges across workers. Key trigger: deadlocks rise with worker count.

Diagnoses Aurora replica lag stuck around 30s behind the writer. Use when read replicas lag and read-after-write consistency breaks. Shows how to match the lag spike to the oldest open transaction on the writer, chunk the offending writes, and rule out replica-side load. Key trigger: lag starts when a long transaction…
