We're actively hiring for database engineers right now. Backups are coming in the next release. Which features from 0.8 aren't there? TSM is an effort, but not never ending. We just refuse to put it out there until we've done enough testing on it to be certain about its robustness. We think the community will be happier if we wait to release it rather than rushing something out that may or may not be ready. That being said, please test out TSM on the 0.9.6 release. I think you'll find that its performance is better than anything we've released previously (including 0.8) and so far we've been able to write far more data into it than in previous 0.9 storage engines. I'm sorry to hear that you had to go back to Postgres for your time series storage. Hopefully our upcoming releases will give you a reason to take another look.

> Which features from 0.8 aren't there? For me, the lack of HISTOGRAM and DIFFERENCE have actually stopped me doing things I wanted to do. Obviously, JOIN isn't there either, although that hasn't been an issue for me. :)

  Ok thanks. Hopefully we'll be able to get to those soon. We have some significant work happening in the query engine that should make it easier to add in new functions (join included). We'll also be writing up instructions for how to contribute new functions. We're trying to make the system simple enough for anyone to come in and add them in without having to know all the database internals.

Thanks for the thoughtful reply! Appreciate the work on performance, its essential and the main motivator to use Influx instead of Postgres. I'll certainly revisit Influx once tsm1 is the default and backups are in :) Re 0.8: As the other poster noted, I think it was related to histograms and/or derivatives - would have to go back to look.

  Yeah, histograms need to be added back in. I just replied to the other poster with a bit more info too. derivative and non_negative_derivative are in the current release. Hopefully 0.10.0 will convince you to come back over :)
