             Summary: jdbc getSchemas method could miss schemas for not started remote caches
                 Key: IGNITE-8100
                 URL: https://issues.apache.org/jira/browse/IGNITE-8100
             Project: Ignite
          Issue Type: Bug
            Reporter: Pavel Kuznetsov


On jdbc side we have org.apache.ignite.internal.jdbc.thin.JdbcThinDatabaseMetadata#getSchemas(java.lang.String,
java.lang.String)

on the server side result is constructed by this:
{noformat}
for (String cacheName : ctx.cache().publicCacheNames()) {
        for (GridQueryTypeDescriptor table : ctx.query().types(cacheName)) {
            if (matches(table.schemaName(), schemaPtrn))
               schemas.add(table.schemaName());
        }
}
{noformat}

see org.apache.ignite.internal.processors.odbc.jdbc.JdbcRequestHandler#getSchemas

This if we have not started cache(with a table) on some remote node, we will miss that scheme.
