LMDB: increase max readers for all databases (journal, kasp, timers..) (!1303) · Merge requests · Knot projects / Knot DNS · GitLab

GitLab now enforces expiry dates on tokens that originally had no set expiration date. Those tokens were given an expiration date of one year later. Please review your personal access tokens, project access tokens, and group access tokens to ensure you are aware of upcoming expirations. Administrators of GitLab can find more information on how to identify and mitigate interruption in our documentation.

Self sign-up has been disabled due to increased spam activity. If you want to get access, please send an email to a project owner (preferred) or at gitlab(at)nic(dot)cz. We apologize for the inconvenience.

Libor Peltan requested to merge lmdb_maxreaders into master Jun 02, 2021

This has 2 consequences:

increased size of lock.mdb file (8k -> 80k) this seems fine since the number of databases is limited for Knot and independent on number of zones
possibly longer linear search in lock table upon txn_begin however, it depends rather on real number of readers than on maximum readers limit
