> SQL functions aliases need to be created for each schema. Their creation runs during cache initialization, but implemented in sequential manner. 
> We can make it in parallel to reduce cache start time.
> Startpoint is org.apache.ignite.internal.processors.query.h2.IgniteH2Indexing.createSqlFunctions() method
