Is there primary key auto generation in distributed environment via INSERT SQL-query?

Is there any method I can use to auto generate (auto increment, for example)
"primary key" (id) of "table" in distributed environment via INSERT
SQL-query? 
If no, what is preferred technique for clustered multithreading system
(UUID, timestamp)?

Hi,

Currently, Ignite doesn't support auto-generate functionality. You are able
to generate IDs manually using distributed atomic sequence provided by
IgniteCacheAtomicSequence [1].
