We simply process a queue of updates from a database table. Some of

adds. We're trying to batch our updates and were hoping to avoid
having to
manage separate files for adds and deletes.
Perhaps a single top-level tag e.g. <update>....</update> could
contain
deletes and adds in the same document?
This would be very complicated from a standpoint of returning errors
to the client.
Keep in mind the <deletes> can never be batched, regardless. The
only command that supports batching is <update> (and it is 1 <update>
with multiple <doc>s, not multiple <update>s).
If you keep a persistent connection open to solr, I don't see why one
command per request should be limiting.
Note also that you can batch on your end. If the deletes are doc
ids, then you can collect a bunch at once and do
<delete><query>id:xxx id:yyy id:zzz id:aaa id:bbb</query></delete> to
perform them all at once.
