We have a simple Patroni config (1 primary + 1 standby). We configured the standby to run 3 hours behind the primary: + recovery_min_apply_delay: '3h' # standby 3 hours behind + synchronous_mode: false # asynchron In case there is a logical problem on the primary (wrong data processing, misleaded application upgrade,…) we want to perform a manual failover to the standby, which still contains
the old, correct data status. That means the standby should __not__ apply any more WALs within the 3 hour residue in the event of a manual failover. When I tried a "patronictl failover" the standby first applied all outstanding WALs (which I don't want) and only then promoted the standby. Any idea? |
