Description

« Hide

Currently, for Read committed transaction, the transactional index is stored in memory. This allows for better performance, but might create OOM for heavily up-datable systems.

An FS based transactional index can be added (naturally, configurable decision between an FS one and an in memory one). This will have an additional future benefit of allowing to resume crashes.

First go at supporting it is there, though not usable. Proved to be more complicated than anticipated, moving it to next release.

Fs transactional log implemented supporting bigger transactions. No support for resuming crashed transactions yet.
