Using NVM Libraries To Add Persistent Memory Support to Apache Kudu Block Cache An early project done with the NVM libraries was adding persistent memory support, both volatile and persistent mode, into the Apache Kudu storage engine block cache. This project required modification of existing code. …

It’s been three months already since the last time I wrote something ;) Time really flies by quickly when you are doing interesting stuff. We’ve been very busy with lots of improvements to the library as well as A LOT of tiny fixes: over the last three months the team eliminated …

In a B+ tree, splitting a full leaf into two leaves is one of its slowest operations, but pmemkv optimizes this using a zero-copy strategy. Rather then copying any key/value data between full and new leaf, pmemkv splits leaves by swapping persistent structures in place. This minimizes write …
