>
> For the share groups fetch request processing, we have an recursive approach
> of dealing with individual fetch requests. While it works fine with less no.
> of records (< 1,000,000) and lesser sharing (< 5 share consumers), it seems
> that some requests are getting stuck when we increase the load and try to
> increase the throughput. I've replaced this approach by removing the
> unlocking and locking of fetch queue in between entries. This had reduced the
> complexity and also removes the reliability issue on increasing the load.
