Good to hear. The actual directory will likely be small in size (number of objects). So it sounds like as long as we manage the number of agreements (2-3) per node then we may be okay. Another quick question, I assume there is a programatic call that can be made to trigger replication push for a supplier.

Is this a hard limit or a soft (reccomendation) limit? That means 4 is the highest number of masters we've tested exhaustively. The protocol supports up to 2^32-2 masters, but you will usually hit a practical limit in the number of replication agreements. Each repl. agreement runs a separate thread, so you will usually be constrained by resources - available RAM, processors, etc. > The application will need to write changes directly to itself on all > servers The application will write the changes directly to each of the 10 masters? > so that they are immediately available locally, then replicated to > other servers. > > Is this possible with FedoraDS?
