InfluxDB v0.9.0 release update 2` The latest update to InfluxDB v0.9.0 includes merging of 44 PRs, adding features such as non_negative_derivative, derivative, and distinct, with count(distinct) coming in the next few days. Minor cosmetic changes to the API are also being made over the next two weeks that may be breaking changes. The release will likely have a more limited clustering feature set due to changes in design, but this implementation will serve as a foundation for future reliable and scalable clustering. A regular release cadence of every 3 weeks is planned, with a mix of feature development and testing before each release.

The InfluxDB team has made significant progress on version 0.9.0, but it's still not ready for release. The main items left to finish are data node shard handling, replacing a downed node, and write back-pressure if data nodes are falling behind on replication. To address these, the team is adding features like selecting tag names in the GROUP BY clause, which was previously counter-intuitive. Despite delays, the team is committed to delivering high-quality software and aims to complete the release by May 31st. The current RCs are not yet true release candidates, but the next one will be once key features are done and show-stopper bugs are fixed. The community's contributions and testing have been invaluable in helping the team move forward. An update on progress will be posted every two weeks until the release.
