-----------------------------------------
was (Author: ptupitsyn):
[~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.

> Java thin 3.0: propagate table schema updates to client on write-only
> operations
> --------------------------------------------------------------------------------

> Key: IGNITE-19241
> URL: https://issues.apache.org/jira/browse/IGNITE-19241
> Project: Ignite
> Issue Type: Improvement
> Components: thin client
> Affects Versions: 3.0.0-beta1
> Reporter: Pavel Tupitsyn
> Assignee: Pavel Tupitsyn
> Priority: Major
> Labels: ignite-3
> Fix For: 3.0.0-beta2
>
>
> 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.
