HBase, Cassandra, Rocksdb, LevelDB and even MONGO now support this approach.The column (Column-per-file) engine for each file is commonly used for database massively parallel processing (MPP), such as redshift or ve

At present, real-time or quasi-real-time Big data models are more and more, technology is not advanced is not the first reason for popularity, the prosperity of community circles is the most important. Mainly has Redshift-An MPP from Amazon supports PB-level databases Hive-translates SQL into Map-reduce tasks based on the SQL engine above Hadoop; Shark-a SQL engine compatible with hive SQL based on the Spark computing framework; Impala-

The Lens provides a unified data analysis interface. Data Analysis task segmentation is achieved by providing a single view across multiple data stores while optimizing the environment for execution. Seamless integration of Hadoop implements functionality similar to traditional data warehouses.Key features of the project: The simple metadata layer provides an abstract view layer for data storage A single shared-mode server, based on Hive meta-storage. Patterns are shared through data pi

[2]As we saw in this article, the vast majority of Postgres's problems come from the Append only mode, which is too redundant for the heap structure.A future versi
