   Looks like we want to add a catchup entry cache. The current entry cache is used for the tailing messages. The current solution looks like to provide a catchup cache by extending the tailing cache, but I think it will not work for the cases that have multiple cursors read from an earlier position such as 3 days but only have entry cache in 2 hours. Essentially, the issue is how to use the cache to speed up multiple subscription catchup reads.
   
   It's better to start a discussion in the dev email thread or start with a proposal.
