Subject [jira] [Commented] (IGNITE-2177) User defined aggregate functions for SQL
Date Sat, 26 Dec 2015 19:40:49 GMT

Dmitriy Setrakyan commented on IGNITE-2177:
-------------------------------------------

Sergi, 

# What is the purpose of the Alias methods?
# Do you mind defining the SqlAggregate function here? I looked at H2 API and don't think
it will apply to us one-to-one. For example, do we need init(...) method?
