find-hypertable-candidates skillA

find-hypertable-candidates is agent-read markdown (skill) from timescale/pg-aiguide: Use this skill to analyze an existing PostgreSQL database and identify which tables should be converted to Timescale/TimescaleDB hypertables. **Trigger when user asks to:** - Analyze database tables for hypertable conversion potential - Identify time-series or event tables in an existing schema - Evaluate if a table would benefit from Timescale/TimescaleDB - Audit PostgreSQL tables for migration to Timescale/TimescaleDB/TigerData - Score or rank tables for hypertable candidacy **Keywords:** h.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified before it reaches your agent: the main file against the SHA-256 recorded here, the others against the git hashes of its source commit. The deterministic audit below grades the latest version, and the same checks always give the same file the same grade.

What the file says

# 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,

How to install

Latest version
mdr add timescale/pg-aiguide/find-hypertable-candidates@git:20260407.0da8f4e
Exact content
mdr add timescale/pg-aiguide/find-hypertable-candidates@sha256:12472d435c00f867

Pin to a label to follow the author's releases, or to a sha256 for exact bytes. Either way the resolved hash is written to mdr.lock, and mdr install fetches those bytes again and checks them, so it installs them exactly or fails.
