[GitHub] [calcite] rubenada opened a new pull request #1119: [CALCITE-2937] Linq4j: implement LazyEnumerable

rubenada opened a new pull request #1119: [CALCITE-2937] Linq4j: implement LazyEnumerable
URL: https://github.com/apache/calcite/pull/1119
 
 
   Implement a LazyEnumerable: an Enumerable whose computation (via a Supplier) will be postponed until it is actually required.
   An example of use case could be CALCITE-2909, where a semiJoin implementation can be optimized by delaying the computation of the innerLookup until the moment when we are sure that it will be really needed, i.e. when the first outer enumerator item is processed.
