Abstract: A method for processing query fault, where a database server receives a query statement and generates a corresponding query plan tree including multiple layers of operators in a pipeline relationship, and each layer includes operation symbols having logical relationship with each other. The server executes the query statement according to the query plan tree, extracts intermediate status information of a faulty operator when a fault occurs in a process of executing the query statement, updates operation symbols of the faulty operator and a logical relationship among the operation symbols according to the query plan tree and the intermediate status information to obtain a reconstructed query plan tree, and continues to execute the query statement according to the reconstructed query plan tree after the fault is recovered.

Abstract: A data processing method and device are provided, where the method includes encoding data by using an arithmetic coding algorithm, so as to obtain a code value interval. When a code value corresponding to the data exists in the code value interval, obtaining the code value according to the code value interval. The method further includes comparing a quantity of bits of the code value with a quantity of bits of the data, so as to obtain a comparison result, and performing a storage operation according to the comparison result.

Abstract: This disclosure provides a clustering storage method and apparatus. The method includes: storing to-be-stored first data row by row into a local memory in a database system; determining a first sorting column, where the first sorting column is used to sort data that has been cached in the local memory; sorting second data according to the first sorting column if the second data that has been cached in the local memory meets a preset condition, where the second data is data, which has been cached into the local memory, in the first data; and storing the sorted second data in a clustering manner into a storage medium in the database system.
