DRILL-7377: Nested schemas for dynamic EVF columns The Result Set Loader (part of EVF) allows adding columns up-front before reading rows (so-called "early schema.") Such schemas allow nested columns (maps with members, repeated lists with a type, etc.) The Result Set Loader also allows adding columns dynamically while loading data (so-called "late schema".) Previously, the code assumed that columns would be added top-down: first the map, then the map's contents, etc. Charles found a need to allow adding a nested column (a repeated list with a declared list type.) This patch revises the code to use the same mechanism in both the early- and late-schema cases, allowing adding nested columns at any time. Testing: Added a new unit test case for the repeated list late schema with content case.
Apache Drill is a distributed MPP query layer that supports SQL and alternative query languages against NoSQL and Hadoop data storage systems. It was inspired in part by Google's Dremel.
Please read Environment.md for setting up and running Apache Drill. For complete developer documentation see DevDocs.md
