COUCHBASE data persistence technical principles and common solutions comparison

CouchBase is a popular NOSQL database that provides multiple data persistence technology to ensure the durable storage of data.In this article, we will introduce the principles of the persistence technology of Couchbase, as well as a common solution comparison. COUCHBASE's data persistence technology mainly includes two types: memory data persistence and disk data persistence.The persistence of memory data is to store data in memory to improve read and write performance.The duration of disk data is to write data into the disk to ensure that the data will not be lost when the server restarts or fails. For the persistence of memory data, the CouchBase uses the Memcached protocol and Ephemeral storage engine.The MEMCACHED protocol is a lightweight network protocol that is used to store and retrieve data in memory.Ephemeral storage engine is a storage engine with memory optimization to manage data storage and retrieval. For the duration of disk data, CouchBase uses its own storage engine and index engine.The storage engine is responsible for writing the data into the disk to ensure that the data is not lost.The index engine is responsible for managing the index of data to improve the detection of data. Common COUCHBASE data duration schemes include: memory -based durable and disk -based durable.The persistence of memory is suitable for scenarios with high requirements for reading and writing performance, and the persistence of disk -based disk is suitable for scenarios that require high data persistence. In short, CouchBase provides a variety of data persistence technologies. Developers can choose appropriate solutions based on actual needs to ensure the durable storage and high -performance access of data.
