@@ -1680,6 +1680,23 @@ Row-level delete changes:
* These position delete files must be merged into the DV for a data file
when one is created
* Position delete files that contain deletes for more than one data file
need to be kept in table metadata until all deletes are replaced by DVs
+Row lineage changes:
+
+* Writers must set the table's `next-row-id` and use the existing
`next-row-id` as the `first-row-id` to create a new snapshot
+ * When a table is upgraded to v3, `next_row_id` should be initialized to 0
+ * It is recommended to increment `next-row-id` by the total
`added_rows_count` and `existing_rows_count` of all manifests assigned a
`first_row_id`
Review Comment:
Added. And I copied this for manifest lists as well ("at least the number of
newly assigned row ids in each manifest")
