Description

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.
