Multitenant implementation

See original GitHub issue

I’m looking at migrating my event sourced / multitenant application to Eventuous. I’ve read through the docs and just want to check if the following is feasible before I dive in:

Each tenant has their own EventStore and database for projections/query models. There are also a few shared projections which are stored in a shared database - this projection would receive events from all tenants and is used for things like listing the tenants etc

My idea is this:

  1. Resolve the tenant information on each request (connection strings, etc)

  2. Change builder.Services.AddSingleton(streamNameMap); to builder.Services.AddScoped(streamNameMap);. Not sure if the CommandService should be / is already scoped to the request.

In order for projections to work, can the ‘global sequence number’ or event number be globally unique/sequential- like using ticks or some other incrementing mechanism?

Ok, the 0.15.0-beta.4 contains the new API. The old API is usable, but marked obsolete. Let me know if it actually help with multi-tenancy, I expect it does.

Let me take a look. I got sidetracked then bogged down in another issue.
