Issue ID: 9652 Summary: Add "tee" capability to load balancer Product: OpenLDAP Version: unspecified Hardware: All OS: All Status: UNCONFIRMED Severity: normal Priority: --- Component: lloadd Assignee: bugs@openldap.org Reporter: mhardin@symas.com Target Milestone: ---
This is a request for an enhancement that would add a "tee" or "fan-out" capability to load balancer, where received operations are sent to two or more destinations simultaneously.
The primary goal or the enhancement is to make it possible to keep multiple independent and likely dissimilar directory systems in lock-step with each other over hours, days, or possibly even weeks.
The enhancement would not necessarily need to include a mechanism for converging the target systems should they become out of sync.
This is not intended to be a replication solution, rather it is viewed more as a "copy" solution intended to be used for specific short-term tasks that need multiple directory systems to be exactly synchronized but where replication is not desirable or even possible.
At least two uses come to mind: 1. Test harnesses, evaluating side-by-side operation of separate directory systems over time
2. Directory system transition validation harnesses
3. (maybe) Part of a test harness to record or replay LDAP workloads
* Other uses?
