mariadb tokudb

We know that the most popular MySQL standalone version is INNODB, the only engine that supports full transactions. Its characteristic is that the data itself is organized by B-TREE, the data itself is a huge B-TREE index based on the primary key clustering. Therefore, the write speed is somewhat reduced, because I/O is required for every write operation to re-arrange the index tree. Especially when the data size is much larger than the memory size, the CPU itself is entangled by disk IO and cann

InnoDB really is a very good storage engine, even high-performance MySQL said, if there is no special requirements, InnoDB is the best choice. Of course, this partial article is about TOKUDB, not innodb, compared to INNODB,TOKUDB has its own characteristics

node has a subset of data. A SQL query is executed on a node that is divided into query fragments sent to its own data. These databases can be scaled linearly by adding additional nodes. The existing databases are: Google spanner, Voltdb, Clustrix, NuoDB. (2) These database systems usually have a single primary node of the data source. They have a set of nodes that are used for transaction processing, which, after being connected to a particular SQL query, takes all the data it needs from the p

It is applicable to the write of access log, relative MyISAM has transactional, and has good compressibility relative to InnoDB.　　INFORBBRIGHT/INFINIDB,OLAP environment: Inferior storage engine, mainly used in OLAP scene, INFINIDB Community Edition can suppor
