SQL pipe syntax was introduced as part of GoogleSQL and is described in a paper "SQL Has Problems. We Can Fix Them: Pipe Syntax In SQL" by Jeff Shute and others[1]. Other vendors, including Firebolt and Databricks, have announced support. I have logged a Jira case to support pipe syntax in Calcite[2].
What do you think of supporting this syntax in Calcite? Is anyone interested in taking on the task? I have sketched out a design in the case, but I would like to hear what people think are the technical challenges in this task.
