>> hi.all，
>> Happy New Year to all the friends in the paimon community，start a vote on
>> Paimon to support Tencent Cloud Cosn。
>>
>> Introduction
>> Tencent COS is a famous object storage system provided by Tencent Corp.
>> Hadoop-COS is a client that makes the upper computing systems based on HDFS
>> be able to use the COS as its underlying storage system. tencent cloud is
>> top 2 cloud vendors in China market and the object store COS （
>> https://intl.cloud.tencent.com/product/cos） is widely used among China’s
>> cloud users but now it is hard for hadoop user to access data laid on COS
>> storage
>>
>> We can use S3 SDK and COSN SDK to access COSN，but
>> 1. When using the s3 protocol to access the fusion bucket, the traffic
>> will pass through the access layer twice, the traffic will be doubled, and
>> the performance will be impaired. This problem will not occur when using
>> cosn.
>> 2. Compared with cos ordinary buckets, fusion buckets have performance
>> advantages in list, rename, truncate and other operations.
>> 3. If you must use the s3 protocol to access cos, we do not recommend
>> using fusion buckets, then the s3 protocol + cos ordinary bucket will
>> encounter some of the above performance issues.
>> 4. Other data lake frameworks also support access to cosn, oss, S3, etc.
>>
>>
>> Optimization methods of cosn:
>> 1. Performance optimization:
>> a. Combined with the architecture of COS fusion bucket, separate metadata
>> flow and data flow to achieve high-performance file semantic access
>> b. Based on COS distributed metadata engine, provide high-performance
>> metadata access
>> c. Provide high-concurrency data flow through pre-reading strategy, block
>> processing and other means
>> 2. Integrate Tencent Cloud service role authentication capabilities to
>> improve access security
>> 3. Integrate Tencent Cloud log reporting capabilities, support task-level
>> log reporting, and improve observability
>>
>> S3 Architecture:
