Compression: a hidden Gem for IO heavy Databases
The limiting factor in most database systems is the ability to read and write data to the IO subsystem.
We're still using storage layouts and methodologies in SQL Server that are a reflection of old spinning media in times gone by.
Until major changes are made to the internal storage layouts, we have "some" hope with options such as data compression, sparse columns and filtered indexes, which not only save space on disk, but also reflect a saving in memory.
In this session we will go over the IO savings technologies presented in SQL Server, and discuss how implementing some of these will assist in your operational performance goals.
