[jira] [Commented] (PARQUET-1968) FilterApi support In predicate

    [ https://issues.apache.org/jira/browse/PARQUET-1968?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17276421#comment-17276421 ] 

Gabor Szadovszky commented on PARQUET-1968:
-------------------------------------------

This one sounds great. Meanwhile, we were talking about the filtering APIs between Iceberg and Parquet with [~rdblue]. It seems that Iceberg's API already contains this feature and it seems to be more clear and usable than the one implemented in Parquet. It might be a good idea to separate this filtering API in Iceberg and use/implement it in Parquet. (See https://github.com/apache/iceberg/blob/master/api/src/main/java/org/apache/iceberg/expressions/Expression.java for Iceberg's API.)
