Tomás Fernández Löbbe commented on SOLR-9045:
---------------------------------------------

I'm a bit too late to this discussion (being released right now as part of 
6.5), but as part of the work in SOLR-10233, I was planning to make 
{{RecoveryStrategy}} an interface, with the current implementation being the 
default, but also add a new {{ReplicateOnlyRecoveryStrategy}} that skips peer 
sync, and jumps directly to replication particularly for "Passive Replicas" (or 
whatever name they end up having). Just FYI, feel free to comment in SOLR-10233

> make RecoveryStrategy settings configurable

> objectives:
>  * to allow users to change RecoveryStrategy settings such as maxRetries and 
> startingRecoveryDelay
>  * to support configuration of a custom recovery strategy e.g. SOLR-9044
> patch summary:
>  * support for optional <recoveryStrategy> solrconfig.xml element added (if 
> element is present then its class attribute is optional)
>  * RecoveryStrategy settings now have getters/setters
>  * RecoveryStrategy.Builder added (and RecoveryStrategy constructor made 
> non-public in favour of RecoveryStrategy.Builder.create)
>  * protected RecoveryStrategy.getReplicateLeaderUrl method factored out 
> (ConfigureRecoveryStrategyTest$CustomRecoveryStrategyBuilder test illustrates 
> how SOLR-9044 might override the method)
>  * ConfigureRecoveryStrategyTest.java using 
> solrconfig-configurerecoverystrategy.xml or 
> solrconfig-customrecoverystrategy.xml
> illustrative solrconfig.xml snippets:
>  * change a RecoveryStrategy setting
> {code}
>   <recoveryStrategy>
>     <int name="maxRetries">250</int>
>   </recoveryStrategy>
> {code}
> * configure a custom class
> {code}
>   <recoveryStrategy 
> class="org.apache.solr.core.ConfigureRecoveryStrategyTest$CustomRecoveryStrategyBuilder">
>     <str name="alternativeBaseUrlProp">recovery_base_url</str>
>   </recoveryStrategy>
> {code}
