Add an option to support cache open read retry on a write lock failure. With this option, as long as read-while-writer is set up following the guidelines in the docs, there should be no need for any plugins to augment the core. Eventual plan is to deprecate collapsed_forwarding plugin with this new support. For more context on this, see https://cwiki.apache.org/confluence/display/TS/Presentations+-+2019?preview=/112821251/132320653/Collapsed%20Forwarding%20.pdf

I've reverted the revert, hence, this is now restored on the 8.1.x branch (but not 8.0.x!). |
