Kept here to make clear that this is a single-batch index. (There are only three subclasses, so keeping it here means we have two copies.) Moving it to the parent says that even a hyper-batch defaults to a single row set. > Provide test tools to create, populate and compare row sets > ----------------------------------------------------------- > > Key: DRILL-5323 > URL: https://issues.apache.org/jira/browse/DRILL-5323 > Project: Apache Drill > Issue Type: Sub-task > Components: Tools, Build & Test > Affects Versions: 1.11.0 > Reporter: Paul Rogers > Assignee: Paul Rogers > Fix For: 1.11.0 > > > Operators work with individual row sets. A row set is a collection of records > stored as column vectors. (Drill uses various terms for this concept. A > record batch is a row set with an operator implementation wrapped around it. > A vector container is a row set, but with much functionality left as an > exercise for the developer. And so on.) > To simplify tests, we need a {{TestRowSet}} concept that wraps a > {{VectorContainer}} and provides easy ways to: > * Define a schema for the row set. > * Create a set of vectors that implement the schema. > * Populate the row set with test data via code. > * Add an SV2 to the row set. > * Pass the row set to operator components (such as generated code blocks.) > * Compare the results of the operation with an expected result set. > * Dispose of the underling direct memory when work is done. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
