------------------------------------------
Summary: Prohibit to set schema for cache without query entities
or allow to create tables on such caches
Key: IGNITE-26755
URL: https://issues.apache.org/jira/browse/IGNITE-26755
Project: Ignite
Issue Type: Improvement
Reporter: Aleksey Plekhanov
When a user sets an SQL schema for a cache and then attempts to execute a
"CREATE TABLE" query, the "Cache is already indexed" exception is thrown. This
happens because using the setSqlSchema method marks the cache as supporting
SQL. However, "CREATE TABLE" queries should only be executed on caches without
this marking.
But cache if we don't have query entities configured cache cannot be considered
as indexed.
To avoid such a problem we should prohibit setting schema without query
entities or allow "CREATE TABLE" on caches with provided schema, but without
query entities (perhaps with check that schema of created table is the same as
cache schema).
