Hi all, I execute simple SQL query and got a unacceptable performance.
I do the following steps: 1. Apply a schema to an RDD and register table. 2. Run sql query which returns several entries: Running time for this query 0.2s (table contains 100000 entries). I think that Spark SQL has full in-memory scan and index might increase performance. How can I add indexes? -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/How-Spark-SQL-supports-primary-and-secondary-indexes-tp22700.html Sent from the Apache Spark User List mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org
