Subject [jira] [Commented] (JCLOUDS-979) BaseJdbcBlobStoreTest.testRanges failure
Date Sat, 01 Aug 2015 15:15:04 GMT

    [ https://issues.apache.org/jira/browse/JCLOUDS-979?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14650379#comment-14650379
] 

Roman Coedo commented on JCLOUDS-979:
-------------------------------------

This bug was introduced with this commit https://github.com/jclouds/jclouds/commit/5ad245dea56b94735cc85c792a19c7121a0eb7dd
which assumes that every local blobstore returns blobs with a ByteArrayPayload or a FilePayload.
This is not the case in JdbcBlobStore.

Changing the way this blobstore handles the payloads is not trivial, since jpa doesn't support
mapping big blobs, we have to chunk every payload and have a special stream which make database
calls to ask for more chunks when needed.
