--------------------------------------
Affects Version/s: 2.16
2.14
> Non-persistent SQL schema isn't merged or validated when node joins cluster.
> ----------------------------------------------------------------------------
>
> Key: IGNITE-24212
> URL: https://issues.apache.org/jira/browse/IGNITE-24212
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.14, 2.16
> Reporter: Vladimir Steshin
> Priority: Minor
> Attachments: TestNonPersistentNodeRestartsWithDynamicSQLTable.java
>
>
> *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. So, the +node has
> not tables whereas the othe cluster does+.
> +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.
