Name

Description

Multi-model database supporting relational and graph data models and built upon PostgreSQL

TimeSeries DBMS for AIoT and BigData

Widely used open source RDBMS

Open-Source and Enterprise in-memory Key-Value Store

Industry standard data logging and graphing tool for time series data. RRD is an acronym for round-robin database.

The data is stored in a circular buffer, thus the system storage footprint remains constant over time.
