How do I choose the best segment_by column?

You should choose a column that is frequently filtered in your queries and has high row density—typically more than 100 rows per value per chunk—such as a device_id or user_id.

What is the benefit of using hypertables in TimescaleDB?

Hypertables automatically partition your data into time-based chunks, allowing for significantly faster inserts and queries on large time-series datasets compared to standard tables.

Should I always enable compression in TimescaleDB?

Compression is recommended for insert-heavy workloads where data is rarely updated, but it should be disabled if your table uses vector types (pgvector) as they are currently incompatible.

When should I use continuous aggregates?

Use continuous aggregates when you need fast access to summarized data, like hourly or daily averages, without recalculating the entire dataset on every query.

Streamlines the design and configuration of high-performance TimescaleDB schemas including hypertables, compression, and automated retention policies.

概要

This skill provides specialized guidance for architecting time-series databases using TimescaleDB. It assists developers in implementing industry best practices for insert-heavy data patterns, such as IoT sensor metrics, event logs, and financial transactions. By offering structured instructions for selecting partition columns, optimizing columnstore compression, and configuring continuous aggregates, the skill ensures that database schemas are tuned for both storage efficiency and query performance. It is particularly useful when transitioning from standard PostgreSQL tables to scaled time-series architectures.
