Among the advantages of a highly distributed system with endless edge points are that you can outsource data collection to a universe of locations, and even include them in your workflow, thereby expanding your operations.
The challenges are when you have endpoints that contribute to your organization and systems, but you don’t exactly trust. They can be newcomers that you don’t know enough about, or entities with a history of misusing the data inclusion to your systems give them access to.
You want the value they create, the information they amass and gather to be copied from the edge up the levels of your system, but you don’t want to give too much for that value, or pay for it in the form of greater risk.
Filtered replication is the art of enabling nontrusted edge points to access your system in a limited manner, replicating the information they produce in a nontrusted format.
RavenDB, a distributed document database for over a decade, enables a system to accept nontrusted data, but to pass it into your database in a secure manner.
Watch RavenDB CEO Oren Eini show you how to expand your distributed system to include non-trusted edge point entities while maintaining permissions, security, and data integrity.
