## What changes were proposed in this pull request? This PR adds 3 optimizer rules for typed filter: 1. push typed filter down through `SerializeFromObject` and eliminate the deserialization in filter condition. 2. pull typed filter up through `SerializeFromObject` and eliminate the deserialization in filter condition. 3. combine adjacent typed filters and share the deserialized object among all the condition expressions. This PR also adds `TypedFilter` logical plan, to separate it from normal filter, so that the concept is more clear and it's easier to write optimizer rules. ## How was this patch tested? `TypedFilterOptimizationSuite` Author: Wenchen Fan <wenchen@databricks.com> Closes #13846 from cloud-fan/filter. |
