EBernhardson (WMF) has uploaded a new change for review.
https://gerrit.wikimedia.org/r/79011
Change subject: New topic action: thread-history
......................................................................
New topic action: thread-history
New index on PostRevision indexes revisions by the root post of their topic
tree. Creates a query-only 'topic_root' field which when queried with
options matching the index will return the sorted history of that topic.
