    • Support multi-thread pre-read in AliyunOSSInputStream to improve the sequential read performance from Hadoop to Aliyun OSS.

    Description

      Currently, AliyunOSSInputStream uses single thread to read data from AliyunOSS, so we can do some refactoring by using multi-thread pre-read to improve read performance.
