In Doris, we disable filesystem cache by default. Paimon use HDFS over S3 sdk to access file on S3. In HDFS, it will generate a file system instance for every split and will save the file system object in a global CACHE. There maybe a policy to evit the expired filesystem in global CACHE object. But if the query has a lot of split, it will generate a lot of file system object in short time. And every file system object will create a thread pool. -- This is an automated message from the Apache Git Service.
