Unlike the scalability design of a cache server cluster, the scalability of the data storage server cluster demands higher data durability and availability.The purpose of the cache is to speed up the data read and reduce the load pressure on the data storage server.Therefore, the loss of some cached data does not affec

Informix Dynamic Server segmented storage, also known as fragmented storage, is based on the principle of regularly dispersed records or indexes in a datasheet to different areas of the disk, to store data on multiple disks, and to increase the efficiency of the database by reducing the competition for disk I/O. In contrast to this is the basic

OverviewSQL Server 2014 is known as a revolutionary version of Microsoft's database, and its performance has been boosted to the greatest extent ever.The updatable Columnstore index, as one of the key features of SQL Server 2014, is a significant contributor to improving query performance in the database. According to Microsoft statistics, in the OLAP query statistics class system, compared to other SQL tra

1. SectionA section (extent) is a basic storage unit used to allocate space for tables and indexes. It consists of 8 contiguous 64KB data pages.The main points of the concept of allocating space based on segments rather than actual use of space: Once the section is full, the space that the next record will occupy is not the size of the record, but the size of the whole new zone. Assign one segment at a time instead of assigning a record.

This article is a high-level guide to the structure of the storage engine, recommending configuration parameters, the best hardware for SQL Server, and innovative ways to store large amounts of data through files and filegroups. This article also outlines the new dynamic features of the SQL Server 7.0 storage engine.
