Pavel Tupitsyn commented on IGNITE-19241:
-----------------------------------------

[~isapego] can you please help me with the C++ client? I'm not sure how to fix 
*table_impl::read_tuples* correctly, do we need *read_array_raw* there? I've 
only changed *packInt* to *packArrayHeader* on the server side.

>
> Currently, Java client receives table schema updates when write-read requests 
> are performed. For example, client performs TUPLE_GET request, sends key 
> tuple using old schema version, receives result tuple with the latest schema 
> version, and retrieves the latest schema.
> However, some requests are "write-only": client sends a tuple, but does not 
> receive one back, like TUPLE_UPSERT. No schema updates are performed in this 
> case.
> To fix this, include the latest schema version into all write-only operation 
> responses:
> * TUPLE_UPSERT
> * TUPLE_UPSERT_ALL
> * TUPLE_INSERT
> * TUPLE_INSERT_ALL
> * TUPLE_REPLACE
> * TUPLE_REPLACE_EXACT
> * TUPLE_DELETE
> * TUPLE_DELETE_ALL
> * TUPLE_DELETE_EXACT
> * TUPLE_DELETE_ALL_EXACT
> * TUPLE_CONTAINS_KEY
> Client will compare this version to the known one and perform a background 
> update, if necessary.
