-----------------------------------------
[~agoncharuk] Hi.
The failure scenario is that cached value can be read on starting remote tx in
case of entry hasn't value and read through configured (when dht prepare
message processed). It's fixed by setting the write flag to txEntry. It'll lead
to including its to dht prepare message. When txHandler will process message it
will not read the cached value on starting remote tx.
For a local cache, the prepare step does not wait for the key's prepare futures
to complete. Multiple threads can process a single value and write it. It's
solved by waiting for prepare future during the prepare step.
