I did check the docs. According to the search, there are like 5 references to "consistency", 4 of which are talking about how traditional databases do that poorly and the 5th one seems to suggest to use "depot partitioner" which seems very much like sharding with per-shard consistency. For "isolation" there are t2 references, for "transaction" 1, none of which explains anything. And I'm sorry, you won't convince me something defined in Java is superior to declarative SQL. There's a lot of problems with SQL, no doubt about it.
