Database instance processing method, system and equipment and storage medium

The embodiment of the invention provides a database instance processing method, system and equipment and a storage medium. In the embodiment of the invention, scene distinguishing is carried out on optimization of the database instance, and the optimization evaluation model adaptive to the optimization scene is adopted to evaluate the optimization effect under the optimization scene for different optimization scenes, so that the accuracy of optimization evaluation can be improved, an accurate judgment basis is provided for the rollback of the executed optimization processing, the probability of invalid optimization of the database instance can be reduced, the probability of reasonable optimization processing of the database instance can be improved, and the execution performance of the database instance can be really improved. 本申请实施例提供一种数据库实例处理方法、系统、设备及存储介质。在本申请实施例中，对数据库实例的优化进行场景区分，针对不同优化场景，采用适配该优化场景的优化评估模型对该优化场景下的优化效果进行评估，可提高优化评估的准确性，进而为是否对所执行的优化处理进行回滚提供准确的判断依据，可降低对数据库实例进行无效优化的概率，提升对数据库实例进行合理优化处理的概率，有利于真正提升数
