Antoine Pitrou updated ARROW-2916:
----------------------------------
Fix Version/s: 2.0.0
> [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: C++ - Plasma
> Reporter: Simon Mo
> Priority: Minor
> Fix For: 2.0.0
>
>
> 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)
> ```
