When user performs column and index modification operation in SQL(ex create index, drop index, add column, drop column), QueryEntity in CacheConfiguration for the modified cache is not updated. Here's my analysis QueryEntity in QuerySchema is a local copy of the original QueryEntity, so the ori

Spark dataframe API will get wrong schema if user executes add/drop column DDL

Currently, when user performs add/remove column DDL, the QueryEntity will not change. This result in Spark getting wrong schema because Spark relies on QueryEntity to construct data frame schema. In Vladimir Ozerov's reply in dev list, http://apache-ignite-developers.2346864.n4.nabble.com/Schema-

Ignite SQL join performance

Currently the only way to join data is nested loops approach stated in this two tickets. https://issues.apache.org/jira/browse/IGNITE-6201 https://issues.apache.org/jira/browse/IGNITE-6202 So we can anticipate the SQL join performance will degrade a lot after the data size reached certain amount.
