SUMMARY:The Iceberg Spec in Motion: v3 Features\, v4 Proposals\, and a Matu
 ring Catalog Ecosystem
LOCATION:Room 2000
DESCRIPTION:Alex Merced\n\nApache Iceberg has become the default table form
 at for the open data lakehouse\, and the specification keeps moving fast. 
 This talk walks through where things stand and where they head next. We st
 art with Iceberg v3 and what it actually changed for practitioners: new da
 ta types\, deletion vectors\, row lineage\, and the features that reshape 
 how engines read and write tables. From there we look ahead to the v4 prop
 osals under active discussion on the dev list\, what problems they aim to 
 solve\, and what they signal about the format’s direction. The second ha
 lf turns to the catalog layer\, the part of the ecosystem that has grown m
 ost chaotic and most important. We map the current landscape\, from the Ic
 eberg REST Catalog spec to Apache Polaris and the wider field of managed a
 nd open options. You will leave understanding how the spec\, the engines\,
  and the catalogs fit together\, and how to make architecture choices that
  hold up as v4 arrives. Whether you run Iceberg in production today or pla
 n your next platform\, this session gives you a clear read on the format
 ’s present and a grounded view of its future.
