When using aws-api, does :PutObject end up bringing :Body fully into memory?

Hmm, yeah I thought so. Getting OOMs. Any workarounds?

multipart uploads

are you uploading from a File source?

kenny16:07:25

Is there an existing example for doing that? If not, will figure it out.

ghadi16:07:43

there is not an existing example

ghadi16:07:02

there's an API to start an upload, then to upload pieces, then to complete the upload

ghadi16:07:20

pieces parts can be uploaded concurrently

Somewhat amusingly, our system uses the -XX:+HeapDumpOnOutOfMemoryError jvm flag. When the app reboots, it will upload the heap dump to s3. The heap dumps are so large that they oom the app again while uploading 😆
