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.
It would be great to have a global functions support. Otherwise, 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
