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)
