Omm is the database administrator (also the OS user running the openGauss), dbgrp is the group name of the OS user running the openGauss, and /opt/software/ openGauss/clusterconfig.xml is the path of the openGauss configuration file. Each line of information is commented out. The information in bold is only an example.

WECHAT TENCENT XLOG FILE HOW TO

The following describes how to create an XML configuration file based on the deployment solution of one primary node and one standby node. You need to configure the configuration file according to the actual deployment requirements. This file is used to guide how to deploy the openGauss. The configuration file in the XML format contains the information about the server where the openGauss is deployed, installation path, IP address, and port number. Installation Creating a Configuration Fileīefore installing the openGauss, you need to create a configuration file. OpenGauss supports automatically adjusting database parameters, reducing the cost and time of parameter adjustment. OpenGauss supports the diagnoser for SQL execution statements, finding out slow queries in advance. OpenGauss supports SQL execution time prediction based on collected historical performance data. OpenGauss integrates AI algorithms into databases, reducing the burden of database maintenance.

OpenGauss supports account management, account authentication, account locking, password complexity check, privilege management and verification, transmission encryption, and operation audit, protecting service data security. With data and indexes stored totally in-memory, a NUMA-aware design, algorithms that eliminate lock and latch contention and query native compilation (JIT), MOT provides low latency data access and more efficient transaction execution. The Memory-Optimized Tables (MOT) storage engine is a transactional rowstore optimized for many-core and large memory and delivering extreme OLTP performance and high resources utilization. The standby node is ready in real time, which can be promoted to primary instantly. Ensure that the redo speed of the standby node keeps up with the generation speed of the primary host. The dispatch thread sends the Xlog to multiple parallel recovery threads to replay. At the mean time, the Xlog is sent to the redo recovery dispatch thread. When the Xlog is transferred to the standby node, the standby node flushs the Xlog to storage medium. Under normal service loads, the RTO is less than 10 seconds, reducing the service interruption time caused by node failure. Optimize SQL execution process through SQL bypass, reducing CPU execution overhead. Optimize atomic operations based on ARM platform LSE instructions, impletmenting efficient operation of critical sections. The global PGPROC array is divided into several parts according to the number of NUMA nodes, solving the bottleneck of ProcArrayLock.īind NIC interrupts to different cores and bind cores to different background threads to avoid performance instability due to thread migration between cores. Malloc key data structures help reduce cross CPU access. For example, CLOG uses partition optimization to solve the bottleneck of ClogControlLock. OpenGauss breaks through the bottleneck of multi-core CPU, 2-way Kunpeng 128 core 1.5 million TPMC.ĭivide key data structure shared by internal threads into different partitions to reduce lock access conflicts. At the meantime, openGauss as a global database open source community, aims to further advance the development and enrichment of the database software/hardware application ecosystem. It optimizes the architecture, transaction, storage engine, optimizer and ARM architecture. openGauss, which is early originated from PostgreSQL, integrates Huawei's core experience in database field for many years.
