* Config default does not comment out EnableSplitstore * Loadability check * Remove test used for debugging * regexp for properly safe check that config is set * regexp for safely matching the EnableSpitstore field in the config * Add instructions for undeleting config and remind users to set splitstore false for full archive * UpdateConfig small docs and functional opts * make gen * Lint * Fix * nil pointer check on validate * Unit testing of EnableSplitstore cases * Address Review --------- Co-authored-by: zenground0 <ZenGround0@users.noreply.github.com>
