Ruben Quesada Lopez commented on CALCITE-2969: ---------------------------------------------- I think there's one small detail that we forgot in this ticket: the file {{algebra.md}} still references the deprecated {{SemiJoin}} when describing the {{semiJoin(expr)}} method: {code} ... | `semiJoin(expr)` | Creates a [SemiJoin]({{ site.apiRoot }}/org/apache/calcite/rel/core/SemiJoin.html) of the two most recent relational expressions. {code} This is no longer correct, since this method creates now a {{Join}} with {{type=SEMI}}. > Improve design of join-like relational expressions > -------------------------------------------------- > > Key: CALCITE-2969 > URL: https://issues.apache.org/jira/browse/CALCITE-2969 > Project: Calcite > Issue Type: Improvement > Components: core > Affects Versions: 1.19.0 > Reporter: Stamatis Zampetakis > Assignee: Danny Chan > Priority: Major > Labels: pull-request-available > Fix For: 1.20.0 > > Time Spent: 31h > Remaining Estimate: 0h > > The existing join-like (Join, SemiJoin, Correlate, etc.) logical and physical > relational expressions have a few design issues which make some parts of the > codebase complicated and difficult to understand. > The goal of this ticket is to improve the design of the respective > expressions based on the discussion in the dev list (see thread [Join, > SemiJoin, > Correlate|https://mail-archives.apache.org/mod_mbox/calcite-dev/201903.mbox/%3C8EEA04A0-4A77-4283-BD20-B019E19AE126%40apache.org%3E]). > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
