> 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
> If we havn't started cache(with a table) on some remote node, we will miss that scheme.
