Rationale for this change
We recently approved and merged the new ALP encoding into parquet-format
However, as @divjotarora points out on the mailing list
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?
Note 1: There is a different ongoing discussion 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?
No
