> There is a discussion on the Substrait mailing list about defining an expression language as part of a text serialization format for Substrait: https://groups.google.com/g/substrait/c/iCiQR-tHI4Q/m/slzrzdcQAgAJ > > Substrait seems like a more appropriate and sustainable place to define an expression language, maintain and version it over time, handle forward and backward compatibility considerations across versions, etc. Of course we will still need Arrow libraries to implement parsers for the expression language. Could the work in this PR be adapted to parse expressions in a language along the lines of what is proposed in that thread on the Substrait mailing list? while the substrait design might be the correct direction to go, but I feel that's a much broader scope compared with this. this PR could bring the preliminaries of filtering into arrow, so some user requests could be fulfilled. and when the substrait integration is mature and complete, this can be switched at that point. all in all, folks, @ianmcook @amol- @westonpace any chance this gets revived and get merged? -- This is an automated message from the Apache Git Service.
