SQL Server 2014

As the field of databases continues to grow with lot of progress in the area of big data, the current crop of relational databases are starting to build in features which are gaining a lot of traction now. The areas are cloud computing, in memory analytics/databases, availability of BI on different platforms such as mobile. As SQL Server 2012 continues to be adopted by different customers, the time to upgrade is a lot slower now because of the complexities/cost involved, Microsoft has announced the next version of SQL Server, SQL Server 2014. I have been talking to some of my colleagues who have SQL Server 2008 right now, one of the topics we discussed was upgrades and they mentioned that they would probably go to SQL Server 2014 directly instead of going to SQL Server 2012 first, I hope that one can migrate to SQL Server 2014 directly. As per Microsoft, "SQL Server 2014 delivers new in-memory capabilities built into the core database for OLTP and data warehousing, which complement our existing in-memory data warehousing and BI capabilities for the most comprehensive in-memory database solution in the market". One of the features to be present in SQL Server 2014 is it introduces hash indexes for memory-optimized tables. Hash indexes are very efficient for point lookups, when you know exactly the value you are looking for. However, they do not perform well if you need a range of value, for example a date range, or if you need to retrieve the rows in a particular order. Apparently Hash Indexes offer better performance for point lookups.
