alamb opened a new pull request, #604: URL: https://github.com/apache/parquet-format/pull/604
- related to https://github.com/apache/parquet-format/issues/533 ### Rationale for this change We recently approved and merged the new ALP encoding into parquet-format - https://github.com/apache/parquet-format/issues/533 However, as @divjotarora points out on the mailing list - https://lists.apache.org/thread/sb4hq0fw19mo8ssov8v87z5jc738qnfd We do not yet have a good way to communicate downstream in the ecosystem how widely supported it is, and when writers could feel safe enabling ALP encoding Thus I think we should communicate this more clearly ### What changes are included in this PR? 1. Add an annotation to ALP saying it is in "preview" 2. Define inline what "preview" means **Note 1**: There is a [different ongoing discussion](https://lists.apache.org/thread/qlf8lg90gqq41lllyy9mk2f0skqvftqj) to formalize the notion of "preview" and versioning in Parquet. If this is approved / agreed, I think we would move the definition of preview elsewhere **Note 2**: @divjotarora I think has proposed an alternative of reverting the ALP encoding from parquet-format until we have finalized the above versioning discussion. ### Do these changes have PoC implementations?
