A data storage method for string data includes: performing pattern matching on each piece of string data in a to-be-stored string data set by using a pattern data set, to determine whether the string data includes matched pattern data in the pattern data set; in response to that the string data includes the matched pattern data, extracting dedicated string data other than the matched pattern data from the string data, and storing the extracted dedicated string data in a dedicated data storage area of the data storage system, wherein an index relationship is formed between the stored dedicated string data and corresponding pattern data stored in the pattern data storage area; and in response to that the string data does not include the matched pattern data, storing original data of the string data in the dedicated data storage area as a whole.

Data storage method and data storage apparatus for string data

Methods, systems, and apparatus for, for data compression based on a key-value store. In one aspect, a method includes generating, at a server, a current dictionary based on a plurality of key-values stored in a storage system of the server; receiving a key-value pair transmitted by a client device; and performing, at the server, data compression on a key-value in the key-value pair by using the current dictionary; and storing the key-value in the storage system of the server.
