What is a time-series database?

A time-series database (TSDB) is optimized for storing, querying, and managing

time-stamped data (data associated with timestamps), often used for tracking events or

metrics over time.

• Use cases: IoT data, server logs, stock prices, sensor data, application monitoring,

etc.

• Characteristics:
• Data is ordered by timestamps.
• Efficient for inserting large volumes of data continuously.
• Optimized for queries that focus on time ranges (e.g., finding data from a

particular hour or day).

• Examples: InfluxDB, TimescaleDB, Prometheus.
