Hi Joshua,

I haven’t used it, but I see these endpoints in indexer/app/main.rb

  get "/" do
    if IndexerCommon.paused?
      "Indexers paused until #{IndexerCommon.class_variable_get(:@@paused_until)}"
      "Running every #{AppConfig[:solr_indexing_frequency_seconds].to_i} seconds. "

  # this pauses the indexer so that bulk update and migrations can happen
  # without bogging down the server
  put "/" do
    duration = params[:duration].nil? ? 900 : params[:duration].to_i
    IndexerCommon.pause duration

Seems to do what you want.

I'm wondering if there's a way to pause the Indexer during a job so that I can let the Indexer do its thing*after* the job completes. I know I can toggle the AppConfig value for the indexer and do a stop/start for the app, but ideally I'd like to do the pause/resume of the Indexer while the job runs.
