<p>Hi Steve, <br>
</p>
<p><br>
</p>
<p>Yeah, so that might be slightly tricky...if a bunch of components are updated, you don't want to trigger multiple EAD exports for each component update, but just a one time EAD export for all the updates. EAD export can really require a lot of SQL queries,
 so that could really kill your database server. <br>
</p>
<p><br>
</p>
<p>But, it that the primary use case for most folks? You want to trigger an EAD export when an associated record ( not just a resource, but a child archival object or instance ) is updated?
<br>
</p>
<p><br>
</p>
<p>If so, I think your wanting to hook into the backend rather than the indexer is actually a better idea...<br>
</p>

<div class="">One idea weíve been batting around here is some sort of messaging system (inspired by Githubís webhooks [1]) which would allow authorized users to activate customizable HTTP callbacks for events, for example creation, modification or deletion
 of a resource or component. It seems like people have taken a number of approaches to figuring out when data changes in AS, but as far as I know all of these involve some sort of regularly scheduled cron job that looks at the Solr index or makes a ton of API
 calls. It would be amazing if the system could send notifications out Ė I think it would allow for much more efficient and flexible integration with other systems.</div>
