Chronix vs TrailDB: What are the differences?

Chronix: A fast and efficient time series storage based on Apache Lucene and Apache Solr. Chronix is built to store time series highly compressed and for fast access times. In comparison to related time series databases, Chronix does not only take 5 to 171 times less space, but it also shaves off 83% of the access time, and up to 78% off the runtime on a mix of real world queries; TrailDB: An efficient tool for storing and querying series of events, by AdRoll. TrailDB's secret sauce is data compression. It leverages predictability of time-based data to compress your data to a fraction of its original size. In contrast to traditional compression, you can query the encoded data directly, decompressing only the parts you need.

Chronix and TrailDB can be primarily classified as "Databases" tools.

Chronix and TrailDB are both open source tools. It seems that TrailDB with 962 GitHub stars and 64 forks on GitHub has more adoption than Chronix with 247 GitHub stars and 23 GitHub forks.
