Introduction Hey there, fellow data enthusiasts! Today, I want to share with you an incredible feature in SQL Server that has completely revolutionized the way we work with external data sources. It’s called PolyBase, and trust me, it’s a game-changer! In this article, we’ll dive deep into the world of PolyBase, exploring its capabilities, benefits, and how it can take your data querying to the…

When it comes to pulling data from another Microsoft SQL Server, two popular options are Linked Server and Polybase. Both technologies enable you to access and query data from remote servers, but they have distinct differences in their implementation and use cases. In this article, we’ll explore the practical applications of Linked Server and Polybase, along with T-SQL code examples, to help you…

Unbelievable SQL SERVER 2016 Feature you should aware.

  Although, I know I am bit late to share this thing on our blog but it says in Indian proverb “Der aai durust aai” means it’s OK you came late but you came that is more important.

Anyways, so you all might aware that Microsoft launched SQL SERVER 2016 officially in June 2016.

You can download the SQL Server 2016 via Link.

Obviously, this is a new revolution in SQL SERVER series. You will find…

How to install PolyBase in SQL Server 2016

How to install PolyBase in SQL Server 2016

Requirements

SQL Server 2016 x64 edition

Oracle Java JRE x64

.NetFramework 4.0

Installation Steps:

Open SQL Server Installation kit and run setup.

Click on Installation and select New SQL Server standalone installation or add features to an existing installation

Select Add features to an existing instance of SQL Server 2016

Select Polybase Query Service for External Data on Feature Selection page

Select use this SQL Server as standalone PolyBase enabled instance on Polybase Configuration page.

Specify a port range for PolyBase Service. By default Polybase is using 16450-16460 port range.

Configure PolyBase Service Account on Server Configuration page.

Click Install.

Check if Polybase was installed in SQL Server 2016

Connect to your SQL Server 2016 Instance using SQL Server Management Studio

Open a new query window.

Execute follow TSQL command:

SELECT SERVERPROPERTY (‘IsPolybaseInstalled’) AS IsPolybaseInstalled;

Microsoft: Ready with “near-final” SQL Server 2016

  Microsoft is almost ready to release the “nearly complete” SQL Server 2016 Release Candidate (RC). According to Mary Jo Foley at ZDNet, a Microsoft representative said the update would be coming out “this week;” the statement was confirmed on March 3. The on premise database platform has been in public preview for some time, and its release is definitely upcoming.

SQL Server 2016 will have an…

Daniel Abadi in an email to Curt Monash analyzing a the Microsoft Polybase paper1:

The basic difference between Polybase and Hadapt is the following. With Polybase, the basic interface to the user is the MPP database software (and DBMS storage) that Microsoft is selling. Hadoop is viewed as a secondary source of data — if you have a dataset stored inside Hadoop instead of the database system for whatever reason, then the database system can access that Hadoop data on the fly and include that data in query processing alongside data that is already stored inside the database system. However, the user must be aware that she might want to query the data in Hadoop in advance — she must register this Hadoop data to the MPP database through an external table definition (and ideally statistics should be generated in advance to help the optimizer). Furthermore, the Hadoop data must be structured, since the external table definition requires this (so you can’t really access arbitrary unstructured data in Hadoop). The same is true for SQL-H and Hawq — they all can access data in Hadoop (in particular data stored in HDFS), but there needs to be some sort of structured schema defined in order for the database to understand how to access it via SQL. So, bottom line, Polybase/SQL-H/Hawq let you dynamically get at data in Hadoop/HDFS that could theoretically have been stored in the DBMS all along, but for some reason is being stored in Hadoop instead of the DBMS.

It’s a long paragraph, but the difference Daniel Abadi is emphasizing is critical: “Hadoop/HDFS data that could theoretically have been stored in DBMS all along”.

According to Microsoft GraySystemsLab page on Polybase: ↩

[…] the goal of the Polybase project is to allow SQL Server PDW users to execute queries against data stored in Hadoop, specifically the Hadoop distributed file system (HDFS). Polybase is agnostic on both the type of the Hadoop cluster (Linux or Windows) and whether it is a separate cluster or whether the Hadoop nodes are co-located with the nodes of the PDW appliance.

And here’re my (very) brief thoughts about Polybase when I first learned about it.

Announced today, Microsoft PolyBase is:

a fundamental breakthrough in data processing used in SQL Server 2012 Parallel Data Warehouse to enable truly integrated query across Hadoop and relational data.

This is a direction almost all analytic databases are taking. Independently or using a well established distribution of Hadoop. Separately there are companies like Hadapt that are offering similar products.

Getting back to PolyBase, according to the docs:

it supports standard T-SQL queries that can join data from tables stored in a relational engine and Hadoop

integrates with Microsoft BI tools
