I'm unsure about the initial setup. Our data engineer handled the implementation. I didn't participate in the process, so I can't speak to how straightforward or complex it was.

The initial setup is complex because this is a distributed system, and you have to make sure that every individual node is aware of every other node in existence. This search engine has a large capacity, so you need to make sure that there is enough buffer space.

We took one month to deploy and perform a fresh setup. Our strategy was to start with a local data center, before venturing into cross data center replicas.

A staff size of two to four people is suitable for deploying and maintaining the solution, depending upon the scale. They would set up the solution and put monitoring in place for the indexing jobs, as well as design the schema so that the data can feed well.

Complex in making system scalable and performant enough.
