Optimizes Performance for the OSS Data Source and Messages in the Console
Feb 24 2020
Features are optimized for the OSS data source. After the optimization, the overall performance of some users is improved by about 22%, and the copy time in the rename process is reduced. TEXT files support the ALTER TABLE ADD Column statement. The number of partitions in a single table in the China (Shenzhen) region cannot exceed 20,000. This prevents partition creation errors. The message "Null IO stream of OSS data sources" is changed to "The type of OSS file system is archive storage type. Change it to the standard storage type". The error message "MetaInfo.SqlExecutor.Parser" is changed to more detailed error information.
