Benjamin Lerer created CASSANDRA-19341: ------------------------------------------
Summary: Relation and Restriction hierachies are too complex and error prone Key: CASSANDRA-19341 URL: https://issues.apache.org/jira/browse/CASSANDRA-19341 Project: Cassandra Issue Type: Improvement Components: CQL/Interpreter Reporter: Benjamin Lerer The {{Relation}} and {{Restriction}} hierarchy have been designed when C* was only supporting a limited amount of operators and columns expressions (single column, multi-column and token expressions). Over time they have grown in complexity making the code harder to understand and modify and error prone. Their design is also resulting in unnecessary limitations that could be easily lifted, like the ability to accept different predicates on the same column. Today adding a new operator requires the addition of a lot of glue code and chirurgical changes accross the CQL layer. Making patch for features such as CASSANDRA-18584 much complex than it should be. The goal of this ticket is to simplify the {{Relation}} and {{Restriction}} hierarchies and modify operator class so that adding new operators requires only changes to the {{Operator}} class and ANTLR file. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
