Small gains can be achieved by removing this extra space from the table. The assumption here is that often data is stored at a fixed length type, such as char 100, and they don’t actually fill the entire 100 characters for every record. The row-level compression works behind the scenes and converts any fixed length data types into variable length types. There are two types of data compression available within SQL Server, row-level and page-level. Prior to this, it was only available on SQL Server Enterprise or Developer editions, not on Standard or Express.

The technique of data compression is available for every database and it’s supported by all the editions of SQL Server 2016 SP1. In general, data compression reduces the space occupied by the data. And then use processing power again, to uncompress the data on the other end. As we know that the network speeds are so much slower than processing speed, it’s possible to find efficiency gains by using the processing power to compress data in a database, so that it travels faster. Data compression takes advantage of this type and helps to increase the efficiency of a database. I/O continues to be a bottleneck in moving information between in-and-out of the database. The idea of data compression is that you can selectively choose tables, indexes, or partitions within a database. Note: Large objects are not compressed (For example, LOB and BLOB)īest suited for the following applications:ĭata compression is a technology that’s been around since SQL Server 2008. Note: If SQL Server is CPU or memory constrained then compression might not suit your environment.

Better performance – reduces the memory footprint of the system.

Safe and faster recovery or restoration.

One must think of deploying data compression for the following benefits: The compression is a technique and, thus, a resource-sensitive operation, but with hardware trade-offs.

Discussion of various types of data compression.

An outline about data is compression techniques.

In this guide, we’ll cover the following topics:

In this article, we are going to learn how the data compression solution can help us optimize the data management solution. How can you increase database performance, lower costs, and eliminate downtime to give your users the best experience possible? Is data compression is an option? Let’s get started and see how some of the existing features can be useful to handle such situations.

A major challenge of every DBA is to discover how to tackle massive data growth, and this is going to be a most important goal. The growing trends predict that 82% of enterprises expect the number of databases to increase over the next 12 months. The database is a critical and vital part of any business or organization.
