Reprint Please specify source: Jiq's technical BlogHBase Features:Recently in the learning Hbase,hbase based on the row Jian is indexed, the query speed will be very fast, completely real-time.But if HBase is to query based on fields other than row health, it can only be a full-fledged scan, which is basically unacceptable.So HBase will generally be designed for specific scenarios to design the health, the use of the real-time query based on row health to achieve real-time HBase data query.A rel

Label:If you need to use multiple databases in your work, and you don't want to switch between multiple clients. Then you need to find a client tool that supports multiple databases.

For the first time in more than 4-5 years, Microsoft has tried to rewrite the query execution engine that was established in SQL Server version 7, released in 1998. The goal of rewriting is to provide a high speed similar to NoSQL without sacrificing the characteristics of the relational database. At the heart of this one attempt is the Hekaton project, the Memory tuning table. Although it can still be acc
