An SRV RR contains a priority value for each of the SRV targets that are present, ranging from 0 - 65535. When caching SRV records we may want to filter out any targets above or below a particular threshold. This change adds support for specifying a lower and/or upper bound on target priorities for any SRV RRs. Any targets returned when resolving the SRV RR whose priority does not fall between the lower and upper thresholds are ignored. For example: Let's say we are running two Redis servers, a primary and cold server as a backup (but not a replica). Both servers would pass health checks, but clearly the primary should be preferred over the backup server. In this case, we could configure our SRV RR with the primary target as priority 1 and backup target as priority 10. The `DISCOURSE_REDIS_HOST_SRV_LE` could then be set to 1 and the target with priority 10 would be ignored. See /t/66045. |
