Hydra Database Activity History

Introduction

Modern database management demands detailed insights into all data operations and user interactions and a proper access to the whole database activity history. Hydra, combining PostgreSQL and DuckDB capabilities, provides foundational activity tracking features. However, in an era where database security and data protection are paramount, organizations need comprehensive solutions that ensure compliance with regulations like GDPR and HIPAA.

Native Activity History Features

Hydra provides built-in capabilities for tracking data activities across both traditional PostgreSQL operations and analytical workloads. By leveraging PostgreSQL's pg_stat_statements extension, Hydra can capture detailed query execution histories, including execution times, query text, and row modifications.

To enable comprehensive query tracking, one could use the following approach:

1. Enable pg_stat_statements: This extension records execution statistics for all queries.

   CREATE EXTENSION IF NOT EXISTS pg_stat_statements;
   

2. Create a logging table: A dedicated table stores snapshots of query execution statistics.

   CREATE TABLE query_log (
       id BIGSERIAL PRIMARY KEY,
       username TEXT,
       query_text TEXT,
       calls INTEGER,
       total_exec_time DOUBLE PRECISION,
       rows BIGINT,
       captured_at TIMESTAMPTZ DEFAULT now()
   );
   

3. Snapshot query statistics: A function extracts data from pg_stat_statements and logs it.

   CREATE OR REPLACE FUNCTION snapshot_query_stats() RETURNS void AS $$
   BEGIN
       INSERT INTO query_log (username, query_text, calls, total_exec_time, rows)
       SELECT
           usename,
           query,
           calls,
           total_exec_time,
           rows
       FROM pg_stat_statements
       JOIN pg_user ON userid = usesysid
       WHERE query NOT LIKE '%pg_stat_statements%'
       AND query NOT LIKE '%query_log%';
   END;
   $$ LANGUAGE plpgsql;
   

4. Capture and view logged queries:

   SELECT snapshot_query_stats();
   
   SELECT username, query_text, calls, round(total_exec_time::numeric, 2) as exec_ms, rows
   FROM query_log
   ORDER BY captured_at DESC, total_exec_time DESC
   LIMIT 5;
   

Example output:

This method ensures that all query activity—including SELECT, INSERT, UPDATE, and DELETE operations—is logged efficiently. Unlike event triggers, which capture only certain database events, pg_stat_statements provides a complete picture of query execution history. Additionally, periodic snapshots can be scheduled using pg_cron to maintain continuous logging. This enables Hydra to maintain detailed, real-time insights into database activity for security, auditing, and performance optimization.
