Hi.

Straight to the topic. Thanks in advance.

 * Does Opencast ingest (or Galicaster) splits a video into several
   segments, in order to process each part by different workers, hence
   increasing process speed? Otherwise, would it make sense? how could
   this be done?

 * As we are interested in faster processing, we thought to ingest,
   encode and do "as most as possible" with locally attached disk, and
   store/publish final videos on NFS. If I understood properly, this
   configuration could work. Am I right?

   org.opencastproject.storage.dir=/data/nfs-path
   org.opencastproject.episode.rootdir=/data/nfs-path
   org.opencastproject.workspace.rootdir=/data/local-path
   
org.opencastproject.staticfiles.rootdir=${org.opencastproject.storage.dir}/staticfiles
   org.opencastproject.file.repo.path= ???

 * According to list comments, multiple engage nodes requiere a
   separate solr node. As stated in
   https://docs.opencast.org/latest/admin/modules/searchindex/:

   /It is important to understand that a solr server provides exactly
   one schema, and one schema only. If you want to cluster both the
   workflow service and the search service, you will need two separate
   solr servers. These solr servers can run on the same machine, but
   each will needs its own servlet container and port./
   //

 * Does that mean I should have a separate solr server for each of the
   following?

   #org.opencastproject.solr.dir=${karaf.data}/solr-indexes
   #org.opencastproject.search.solr.url=http://solr:8983/solr/
   #org.opencastproject.archive.solr.dir=${org.opencastproject.solr.dir}/archive
   
#org.opencastproject.scheduler.solr.dir=${org.opencastproject.solr.dir}/scheduler
   #org.opencastproject.search.solr.dir=${org.opencastproject.solr.dir}/search
   #org.opencastproject.series.solr.dir=${org.opencastproject.solr.dir}/series
   
#org.opencastproject.workflow.solr.dir=${org.opencastproject.solr.dir}/workflow

 * Do I have to copy
   
matterhorn/modules/matterhorn-search-service-impl/src/main/resources/solr/conf,
   and
   
matterhorn/modules/matterhorn-workflow-service-impl/src/main/resources/solr/conf
   files to solr servers?
   Please, observe documentation is explaining how to deploy a solr,
   instead of how opencast should be linked to a solr server (which,
   IMHO, might do)

 * Why custom_properties contains a
   /org.opencastproject.elasticsearch.config.dir/ property? wasn't
   opencast using solr already?

 * Sorry to bother, but I still haven't figured out the proper values
   for a multi-service-node environment. Please, confirm they are ok:

   org.opencastproject.organization-mh_default_org.cfg
   server=domain.com
   prop.org.opencastproject.admin.ui.url=http://admin:8080
   prop.org.opencastproject.engage.ui.url=http://engage:8080
   custom.properties
   org.opencastproject.server.url=https://domain.com   #please, note
   the httpS
   org.opencastproject.jobs.url=engage???

   Actually, these aren't working for LTI, but that's another issue.


For sure, more to come...
Regards
