Can you name popular time series data storage systems?

Popular data storage systems for time series (Time Series Databases, TSDB) include:

• InfluxDB — a specialized TSDB with a powerful query language and support for high loads.
• Prometheus — focused on monitoring and alerting, widely used in DevOps.
• TimescaleDB — an extension for PostgreSQL, combining the capabilities of relational databases and TSDB.
• OpenTSDB — built on top of HBase, scalable for large volumes of data.
• Graphite — a system for collecting and visualizing time series.

The choice depends on scalability requirements, integration, and data specifics.
