* Preserve column order in DruidSchema, SegmentMetadataQuery. Instead of putting columns in alphabetical order. This is helpful because it makes query order better match ingestion order. It also allows tools, like the reindexing flow in the web console, to more easily do follow-on ingestions using a column order that matches the pre-existing column order. We prefer the order from the latest segments. The logic takes all columns from the latest segments in the order they appear, then adds on columns from older segments after those. * Additional test adjustments. * Adjust imports. |
