Is datahike-lmdb ready for usage yet? With which versions of datahike will it work? With latest 0.7.x versions https://github.com/replikativ/datahike-lmdb.

The konserve-lmdb backend is still beta, but I have used it quite a bit across benchmarks and projects. I haven't used the datahike-lmdb backend lately though, I suspect it needs updates for the new persistent-sorted-set format.

Try to use the latest version https://github.com/replikativ/datahike-lmdb/commit/9136ec43fc7d4cfa59345072740c5f9af56fb889, it passes tests against the latest Datahike release for me. Thanks for reminding me of this.

Please report if you run into any more issues with it. I want to make it an official backend, but the LMDB integration is a special case and a bit more directly tied into the storage stack (that is why you still need datahike-lmdb, while all other storage backends only need the respective konserve backend dependency). For instance LMDB handles memory off JVM which the other storage backends don't do in the same way.

For anybody else interested, datahike-lmdb should work again with the latest datahike version.
