What does this MR do and why?
resource_link_events
table needs to be backfilled based on the data from system_note_metadata
and notes
.
This MR prepares the async addition of a DB index to facilitate the backfilling which will be done via batched background migration.
The index targets the table system_note_metadata
. A synchronous creation takes more or less an hour.
