Label:As the number of rows in the table increases, so does the impact of management and performance performance. Backups will take more time, recovery will take more time, and queries over the entire data table would take more time. By dividing the rows in a table into sections, you can reduce the management and performance problems of large tables, and the method of partitioning the publication data is called partitioning the table. Advantages of Partitioned Tables: (1) Improve query performan

Data partitioningRedis clusters store data on multiple nodes, that is, different partitions are stored on different nodes, and each node can store multiple partitions. Each partition is also referred to as a "hash slot" in Redis, with a total of 16,384 partitions planned in the Redis cluster. For example: when there are 3 nodes in a cluster, Node A will contain 0-5460 partitions, Node B will contain 5461-10922 partitions, and node C will contain 10923

benefits to a wide variety of applications by improving manageability, performance, and availability. In general, partitioning can greatly improve the performance of certain queries and maintenance operations. In addition, partitioning can greatly simplify common administrative tasks, and partitioning is a key tool for building gigabytes of data systems or ultra-high availability systems. The partitioning feature can further subdivide a table, index, or index organization table into segments, w

Label:When we have a larger amount of data, we need to split the large table into smaller tables, then queries that only access departmental data can run faster, the basic principle being that the data to be scanned becomes smaller. maintenance tasks (for example, rebuilding an index or backing up a table) can also run faster. We can no longer get the partition by physically placing the table on multiple disk drives to split the table. If you place a
