* Always use file sizes when determining batch ingest splits. Main changes: 1) Update CloudObjectInputSource and its subclasses (S3, GCS, Azure, Aliyun OSS) to use SplitHintSpecs in all cases. Previously, they were only used for prefixes, not uris or objects. 2) Update ExternalInputSpecSlicer (MSQ) to consider file size. Previously, file size was ignored; all files were treated as equal weight when determining splits. A side effect of these changes is that we'll make additional network calls to find the sizes of objects when users specify URIs or objects as opposed to prefixes. IMO, this is worth it because it's the only way to respect the user's split hint and task assignment settings. Secondary changes: 1) S3, Aliyun OSS: Use getObjectMetadata instead of listObjects to get metadata for a single object. This is a simpler call that is also expected to be less expensive. 2) Azure: Fix a bug where getBlobLength did not populate blob reference attributes, and therefore would not actually retrieve the blob length. 3) MSQ: Align dynamic slicing logic between ExternalInputSpecSlicer and TableInputSpecSlicer. 4) MSQ: Adjust WorkerInputs to ensure there is always at least one worker, even if it has a nil slice. * Add msqCompatible to testGroupByWithImpossibleTimeFilter. * Fix tests. * Add additional tests. * Remove unused stuff. * Remove more unused stuff. * Adjust thresholds. * Remove irrelevant test. * Fix comments. * Fix bug. * Updates. |
