Problems solved by technology

However, this solution is inefficient when dealing with small data objects, because in small data objects, the data lengths of Metadata, Key and Value are not much different, and even the data lengths of Metadata and Key are greater than the data length of Value
According to the information released by Facebook, most of the data objects stored in memory storage are small data objects, and even more than 40% are smaller than 11bit, indicating that most of the data are small data, and this kind of partial code storage The scheme cannot take advantage of EC coding, which makes the data storage redundant and increases the storage cost.

Abstract

The invention discloses a data processing method. The method comprises the steps of coding a data block with a predetermined size to generate an error correction data block corresponding to the data block, wherein the data block comprises data objects, and the data objects include a keyword, a value and metadata; and generating a data block index and data object indexes, wherein the data block index is used for indexing the data block and the error correction data block corresponding to the data block, and the data object indexes are used for indexing the data objects in the data block, and each data object index is used for indexing only one data object.

Description

technical field [0001] The present invention relates to the computing field, and more particularly, to a data processing method, system and device. Background technique [0002] With the decline of memory prices, distributed memory storage systems are widely used in distributed computing systems to store hot data, among which key-value (KV) pair storage is the most widely used data storage method, currently Mainstream commercial products include Memcached, Redis, RAMCloud, etc., which are commercially used in the data storage systems of Twitter, Facebook, and Amazon. [0003] The mainstream fault-tolerant method of the distributed memory storage system is mainly the full backup scheme, which is to copy a piece of data to different devices as a whole. When some devices fail, the backup data on other non-failed devices can be used to restore Recover data from failed devices. This implementation scheme is simple and reliable, but there is a large data redundancy, and at least...
