Time series data is data that contain a series of timestamps and special values. Plenty of industrial areas generate time series and are used for the monitoring system. The amount of collected data and operational analysis required a new type of database: Time Series Databases, which are specialized for storing and querying time series data. In this paper, we propose a list of popular time series databases and a feature list of open-source databases. The search resulted in 4 databases. Therefore, five criteria are defined: speed of writing and reading, size of the database, support time-series table, and convenience of API.
