[dagit] Assets: Only show latest materialization in list

Authored by dish on Apr 16 2021, 8:00 PM.



When viewing a list of an asset's partitioned materializations, bucket them by partition and only show the most recent one in the table. If there are predecessor materializations (by timestamp), link to a dialog that displays these in the same style of table.


  • Put the partition name in the leftmost column, as it is the most key-like value.
  • Sort the table by partition name, with partition-less materializations at the bottom.
Test Plan

View an asset, switch to the list view of materializations. For partitions (or non-partiioned materializations) with predecessors, verify correct rendering of ButtonLink and its dialog.

This seems like a good workflow improvement! Certainly makes the list easier to scan through and emphasizes that the graphs, etc. also only show the most recent run for the partition.


I feel like this may not need to be both optional and also | null?
