techniques for migrating data from multiple streams to the read side of an application

EventStoreDB
1

Hi,

I’m trying to migrate data from streams to a document database to use as the read side of an application. Other than using subscriptions and having clients, could I use a ES plugin?

Correct me if I’m wrong, but there’s no way to subscribe to multiple streams with one subscription, other than subscribing to all streams.

Any advice appreciated.

Cheers

Sean.

You can also use thing like the category projection or a custom
projection to get combined streams. EG with by_category enabled all
events from streams named account-000001 account-000002 etc will be
available in $ce-account

Hi Greg,

Is $ce-account the stream I should subscribe to to get all events from streams as described in your previous message?
