[jira] [Created] (ARROW-2916) [C++] Plasma Seal is slow due to hashing

Simon Mo created ARROW-2916:
-------------------------------

             Summary: [C++] Plasma Seal is slow due to hashing
                 Key: ARROW-2916
                 URL: https://issues.apache.org/jira/browse/ARROW-2916
             Project: Apache Arrow
          Issue Type: New Feature
          Components: Plasma (C++)
            Reporter: Simon Mo


When I writes a 1MB tensor into plasma, it takes about 2ms. 50% of time is spent sealing the object. Can we add a flag to the Seal API to disable to hashing when needed?

 

For example:

```
 Status PlasmaClient::Seal(const ObjectID& object_id, bool hash_flag)
 ```
