identifying original SQL functions after rewrites (in adapters)

Hello, I’m trying to implement COALESCE for elastic adapter and would like to know what is recommended approach to identify original function (after possible rewrites). Let me give an example. Currently calcite converts COALESCE(attr, 'foo') into CASE(IS NOT NULL(attr), attr, 'foo'). So in

Re: Maven wrapper

Please review https://github.com/julianhyde/calcite/tree/2112-mvnw , and give it a try in your own sandbox. I have built on the original patch. We no longer need to include a .jar or .java. And I’ve updated the documentation to use ‘./mvnw’

Re: joins and low selectivity optimization

Hive actually does this optimization (it is called semi-join reduction) by generating bloom-filters on one side and passing it on to the other side. This is not a rewrite but instead a physical implementation. Vineet On Aug 29, 2018, at 10:34 AM, Vladimir Sitnikov
