It really sounds like they should take a look at this: https://github.com/LiveAsynchronousVisualizedArchitecture/simdb https://github.com/LiveAsynchronousVisualizedArchitecture/si... "One appealing aspect of LMDB is its relative ease of use from multiple processes, above and beyond its basic capabilities as yet-another-fast-key-value-store." simdb is only lock free and thread safe. While LMDB is benchmarked at around 10k writes, this should be able to do millions of mixed reads and writes with 4 modern cores. LMDB seems to use a separate lock file to sync multiple threads/processes. The only catch here is that the keys aren't sorted, which doesn't seem to be a requirement of theirs.
