IndexSentry

IndexSentry is a web app (with an optional lightweight agent) that continuously audits and tunes indexing and query patterns for production NoSQL databases. It connects read-only to MongoDB, DynamoDB, and Couchbase, samples slow queries, correlates them with index coverage, and flags high-impact fixes: missing/unused indexes, hot partitions, unbounded scans, and schema drift that breaks performance. It generates safe, reviewable change plans (e.g., index create/drop statements, DynamoDB GSI recommendations, partition key alternatives) and estimates cost/perf impact before you touch production. This is a combination traditional + AI app: traditional telemetry and rules catch the obvious issues; AI summarizes findings, proposes options, and writes PR-ready migration notes/runbooks. It’s not a “magic optimizer”—it’s a pragmatic guardrail that helps teams avoid the common NoSQL foot-guns that quietly turn into outages and massive cloud bills.
