Abstract

The invention discloses a database data management method and device, electronic equipment and a computer readable storage medium. A database is provided with more than two tables with the same format, all rows of each table are provided with row primary key values, each table comprises at least one corresponding partition, and each partition is provided with a specific partition server, and the method comprises the following steps: determining object attributes of data to be written as the row primary key values in a table to be stored, wherein the to-be-stored table is a table used for storing the to-be-written data in the more than two tables with the same format; determining table serial numbers of the to-be-stored tables according to the row primary key values and the number of the tables; determining a to-be-stored partition based on the table serial number of the to-be-stored table and the row primary key value, wherein the to-be-stored partition is a partition where the row primary key value is located in the to-be-stored table; and writing the to-be-written data into a partition server corresponding to the to-be-stored partition.

Description

technical field [0001] The present invention relates to the technical field of cloud storage, in particular to a database data management method, device, electronic equipment and computer storage medium. Background technique [0002] Non-relational databases (NoSql) with partially distributed storage, such as HBase and HyperTable, when writing and reading data, divide the data into different rows according to the row key (Rowkey) of each row of data in lexicographical order. Each region is assigned to a different region server in the cluster. When a large number of rows with the same prefix of the primary key are written, it will cause excessive traffic on the partition server, resulting in performance degradation or even unavailability of hot spots. In related technologies, one way is to use hash hash to rehash the row primary key value to distribute the data to different partitions; the other way is to reduce the regularity of the row primary key value by randomly prefixi...
