# PostgreSQL Hypertable Candidate Analysis Identify tables that would benefit from TimescaleDB hypertable conversion. After identification, use the companion "migrate-postgres-tables-to-hypertables" skill for configuration and migration. ## TimescaleDB Benefits **Performance gains:** 90%+ compression, fast time-based queries, improved insert performance, efficient aggregations, continuous aggregates for materialization (dashboards, reports, analytics), automatic data management (retention, compression). **Best for insert-heavy patterns:** - Time-series data (sensors, metrics, monitoring) - Event logs (user events, audit trails, application logs) - Transaction records (orders, payments, financial) - Sequential data (auto-incrementing IDs with timestamps) - Append-only datasets (immutable records, historical) **Requirements:** Large volumes (1M+ rows), time-based queries, infrequent updates ## Step 1: Database Schema Analysis ### Option A: From Database Connection #### Table statistics and size ```sql -- Get all tables with row counts and insert/update patterns WITH table_stats AS ( SELECT schemaname, tablename, n_tup_ins as total_inserts, n_tup_upd as total_updates, n_tup_del as total_deletes, n_live_tup as live_rows, n_dead_tup as dead_rows FROM pg_stat_user_tables ), table_sizes AS ( SELECT schemaname, tablename, pg_size_pretty(pg_total_relation_size(schemaname||'.'||tablename)) as total_si
