# TimescaleDB

> **Definition:** TimescaleDB is an open-source time-series database extension for PostgreSQL that optimizes database performance for time-series logging, IoT telemetry, and high-frequency operational metrics.

## In depth

Time-series datasets (like IoT sensor metrics or stock tickers) grow rapidly, causing standard relational database indexes to degrade. TimescaleDB solves this by partitioning tables into 'hypertables' based on time intervals, maintaining high write speeds and sub-millisecond query performance even with billions of records.

## How ERPStack applies this

We deploy TimescaleDB instances for clients with high-frequency telemetry, such as AgTech field sensors or mining logistics tracking, keeping querying latency low.
