One of the popular new Big Data SQL features is its Query Server. You can think of Query Server as an Oracle Database 18c query engine that uses the Hive metastore to capture table definitions. Data isn’t stored in Query Server; it allows you to access data in Hadoop, NoSQL, Kafka and Object Stores (Oracle Object Store and Amazon S3) using Oracle SQL. Installation and Configuration Architecturally, here’s what a Big Data SQL deployment with Query Server looks like: There...

Big Data SQL 4.0 introduces a data processing enhancement that can have a dramatic impact on query performance: distributed aggregation using in-memory capabilities. Big Data SQL has always done a great job of filtering data on the Hadoop cluster. It does this using the following optimizations: 1) column projection, 2) partition pruning, 3) storage indexes, 4) predicate pushdown. Column projection is the first optimization. If your table has 200 columns – and you are only...

In Hadoop world Kerberos is de facto standard of securing cluster and it's even not a question that Big Data SQL should support Kerberos. Oracle has good documentation about how to install Big Data SQL over Kerberized cluster, but today, I'd like to show couple typical steps how to test and debug Kerberized installation. First of all, let me tell about test environment. it's a 4 nodes: 3 nodes for Hadoop cluster (vm0[1-3]) and one for Database (vm04). Kerberos tickets should...
