EventStore ReadAllEventsForwardAsync is populating all of the data from all services

[DureSameen]

We have a single eventstore connected to all microservices. Now we are creating a data retrieval logic, to populate a microservice data in the startup. But the following line populating all data even from other services too. so it is causing exception in serialization

allEventsSlice = await _connection.ReadAllEventsForwardAsync(nextPosition, pageSize, false) ;

How can we populate a single type only i-e only from following types.

var typeList = _dataRetrievalConfiguration.ReadModelAssembly.DefinedTypes.Where(type => type.Name != "LookUpEnumReadModel" && !type.IsInterface && !type.IsAbstract && type.ImplementedInterfaces.Any(inter=> inter == typeof(IReadModel))).ToList(); typeList.ForEach(async x => { await _populator.PopulateAsync(x, cancellationToken); });

Hi @DureSameen I'm not very familiar with EventStore, but would you be able to create a small exploratory test that illustrate your problem?

If there is a but, we'll need a fix for it.

I have created two microservices

https://github.com/DureSameen/EventFlowWithElasticSearch/tree/DataRetreveial https://github.com/maree16/EventFlowForOrganization

The first one include logic of data retrieval.

1. Create environment variables. as described in readme.
2. Add some data using both api
3. Turn on data retrieval switch in write api ,
4. All data from eventstore will read to the data retrieval routine.

Hi @DureSameen none. The EventStore part of EventFlow is mainly maintained by others. Would you be up for doing a pull request for it?
