Name

Description

A widely adopted Java cache with tiered storage options

An open source graph database built for real-time streaming and compatible with Neo4j

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.

Cloud-based data warehousing service for structured and semi-structured data
