Vladimir Steshin updated IGNITE-24212:
--------------------------------------
Description:
*Consider:*
1) There is a working non-persistent cluster with predefined caches in
_IgniteConfiguration_.
2) The caches have no SQL-entities set.
3) A node creates a table over one of those cache with `_CREATE TABLE IF NOT
EXISTS_`. A SQL table and a schema appear in the cluster.
4) One of the nodes restarts.
5) Next `_SELECT_` queries to the table may fail with '_TABLE NOT FOUND'_
6) Restarted node has no tables in system view '_TABLES_'.
*Cause:*
The node restarts with predefined cache configuration having no SQL entities
set. When node joins cluster, dynamic tables/schema seem not merged or
validated. The restarting node takes the predefined cache configuration as is
without receiving the dynamically created schema and table .
+This works+ with the persistence because node stores and reads the cache meta
holding the schema/entities.
*Workarounds:*
1) Do not predefine caches, create them with `_CREATE TABLE_`
2) Set matching SQL entities in the predefined cache config.
3) Use other cache names with `_CREATE TABLE_` (_WITH "CACHE_NAME=._..).
*Suggestions:*
1) Validate schema/caches and do not allow node join cluster.
or
2) Merge static and dynamic schemas/cache configs and send them to the joining
node.
