I’m quite happy with it, except for some problems I found recently. Unfortunately it does not seem to be under active development, I have sent a pull request to have it working with latest pandas and dask but no answer so far.

I store daily price bars for many stocks and ETFs and it works quite well. The library is really simple so it’s easy to go through the code if needed.

I haven’t seen many options available on this space, there is ArticDB, but it’s not open source. And from what I understand a “production” DB requires a paid license. So I won’t spent time building my code around it.

Do you know any other alternatives on this space?
