>             Project: Solr
>          Issue Type: Bug
>          Components: replication (java)
>    Affects Versions: 4.7
>         Environment: Redhat Linux 64bit
>            Reporter: Forest Soup
>            Priority: Critical
>              Labels: performance

> If there are >100 docs gap between the recovering node and the good node, the solr will do snap pull recovery instead of peersync.
> Can the 100 docs be configurable? For example, there can be 10000, 1000, or 10 docs gap between the good node and the node to recover.
> For 100 doc, a regular restart of a solr node will trigger a full recovery, which is a huge impact to the performance of the running systems
> Thanks!
