Wes McKinney reassigned ARROW-1775: ----------------------------------- Assignee: Stephanie Wang > Ability to abort created but unsealed Plasma objects > ---------------------------------------------------- > > Key: ARROW-1775 > URL: https://issues.apache.org/jira/browse/ARROW-1775 > Project: Apache Arrow > Issue Type: New Feature > Components: Plasma (C++) > Reporter: Stephanie Wang > Assignee: Stephanie Wang > Labels: pull-request-available > Fix For: 0.8.0 > > > It would be useful to allow a Plasma client to abort an object that it > created but hasn't yet sealed. After the abort, it should appear as if the > object was never created all. The logic is similar to the delete case, except > that the client must release the object atomically with the removal of the > object from the cache and store. > In Ray, for example, we need this for the distributed version of the Plasma > store, where many Plasma clients transfer objects to each other. If a sending > Plasma client fails during a transfer, we want to make sure that the > receiving client can abort the transfer, so that we can later recreate the > object successfully. Otherwise, we will fail with an error that the object > already exists. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
