Kostas Kloudas updated FLINK-9752: ---------------------------------- Fix Version/s: (was: 1.6.2) > Add an S3 RecoverableWriter > --------------------------- > > Key: FLINK-9752 > URL: https://issues.apache.org/jira/browse/FLINK-9752 > Project: Flink > Issue Type: Sub-task > Components: Streaming Connectors > Reporter: Stephan Ewen > Assignee: Kostas Kloudas > Priority: Major > Labels: pull-request-available > Fix For: 1.7.0 > > > S3 offers persistence only when uploads are complete. That means at the end > of simple uploads and uploads of parts of a MultiPartUpload. > We should implement a RecoverableWriter for S3 that does a MultiPartUpload > with a Part per checkpoint. > Recovering the reader needs the MultiPartUploadID and the list of ETags of > previous parts. > We need additional staging of data in Flink state to work around the fact that > - Parts in a MultiPartUpload must be at least 5MB > - Part sizes must be known up front. (Note that data can still be streamed > in the upload) -- This message was sent by Atlassian JIRA (v7.6.3#76005)
