     [ https://issues.apache.org/jira/browse/IGNITE-4108?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andrew Mashenkov updated IGNITE-4108:
-------------------------------------
    Description: 
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 or create bulk query or make in background to reduce cache start time.

Startpoint is org.apache.ignite.internal.processors.query.h2.IgniteH2Indexing.createSqlFunctions() method
