--------------------------------------

             Summary: Support column selectivity calculation for SQL
                 Key: IGNITE-3171
                 URL: https://issues.apache.org/jira/browse/IGNITE-3171
             Project: Ignite
          Issue Type: Improvement
            Reporter: Sergi Vladykin


Need to support ANALYZE command. http://h2database.com/html/grammar.html#analyze

Currently H2 explicitly ignores external table engines (don't see any reasons why). Probably we have to fix H2 by adding method Table.canAnalyze() and use it in that check.

Also when IGNITE-1232 will be merged we'll need to propagate this statistics to clients.
