This article explains why a tenant in OceanBase may experience frequent mini compactions, shows how to locate the responsible DML statements by querying merge info and tablet IDs, demonstrates the process with test tables, and provides conclusions and references for further investigation.
The article demonstrates how MySQL Router 8.2 enables transparent read/write splitting for an InnoDB ReplicaSet, showing the architecture, configuration steps, connection behavior, and the generated routing settings that improve database performance without modifying application code.
This article explains how MySQL Router 8.2 enables read/write splitting for an InnoDB ReplicaSet, showing configuration steps, routing behavior, sample code, and the resulting performance and management benefits without requiring application changes.
MySQL 8.2 introduces transparent read/write splitting via MySQL Router, allowing automatic routing of read traffic to replica instances and write traffic to the primary source without any changes to the application, demonstrated with a simple InnoDB ReplicaSet deployment and configuration examples.
This article explains the basics of MySQL master‑slave replication, illustrates how read/write splitting works to alleviate performance bottlenecks, and shares practical test results showing reduced latency on the master and improved overall throughput when directing reads to replica servers.
This article investigates why the Seconds_Behind_Master metric fluctuates in a dual‑master MySQL setup, explains the underlying replication logic, reproduces the issue, and analyses the handling of ROTATE_EVENT and other binlog events in both parallel and non‑parallel replication modes using source code excerpts.
This article explains how to use HBase's built‑in PerformanceEvaluation tool to run baseline read/write latency tests (P99 and P999), describes key command‑line parameters, presents benchmark results for random and sequential operations, and discusses the implications for HBase performance tuning.
