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...

One of the major Big Data SQL benefits is security. You deal with the data, which you store in HDFS or other sources, through Oracle Database, which means, that you could apply many Database features, such as Data Redaction, VPD or Database Vault. These features in conjunction with database schema/grant privileged model, allows you to protect data from Database side (when intruder tries to reach data from database side). But it's also important to keep in mind, that Data...

One of Big Data SQL’s key benefits is that it leverages the great performance capabilities of Oracle Database 12c. I thought it would be interesting to illustrate an example – and in this case we’ll review a performance optimization that has been around for quite a while and is used at thousands of customers: Materialized Views (MVs). For those of you who are unfamiliar with MVs – an MV is a precomputed summary table. There is a defining query that describes that summary. ...

But now I want to talk about why do you want to run queries over Kafka. Here is Oracle concept picture on Datawarehouse: You have some stream (real-time data), data lake where you land raw information and cleaned Enterprise data. This is just a concept, which could be implemented in many different ways, one of this...
