Epam.Kafka.PubSub.EntityFrameworkCore

About

Epam.Kafka.PubSub.EntityFrameworkCore package provides entity framework core implementation for key abstractions defined in Epam.Kafka.PubSub.

Key Features

  • Base abstract classes DbContextSubscriptionHandler<TKey, TValue, TContext>, DbContextEntitySubscriptionHandler<TKey, TValue, TContext TEntity> to help with implementation of ISubscriptionHandler<TKey, TValue> that read data from KAFKA topics and save it to database using DbContext.
  • Default implementation of IExternalOffsetsStorage that store offsets in database via DbContext. TryAddKafkaDbContextState extension method to register it in IServiceCollection.
  • Base abstract classes DbContextPublicationHandler<TKey, TValue, TEntity, TContext> and DbContextEntityPublicationHandler<TKey, TValue, TEntity, TContext> to help with implementation of IPublicationHandler<TKey, TValue> that read data from database using DbContext and publish it to kafka topics.

How to Use

Store subscription offsets

Prepare context.

public class SampleDbContext : DbContext, IKafkaStateDbContext
{
    public DbSet<KafkaTopicState> KafkaTopicStates => this.Set<KafkaTopicState>();

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);

        modelBuilder.AddKafkaState();
    }
}

Register services and setup topic partition assignment and offsets storage for subscription.

services.TryAddKafkaDbContextState<SampleDbContext>();

KafkaBuilder kafkaBuilder = services.AddKafka();
kafkaBuilder.AddSubscription<string, KafkaEntity, SubscriptionHandlerSample>("Sample")
            .WithSubscribeAndExternalOffsets();

Publish data from database to kafka

Optionally derive entity from IKafkaPublicationEntity interface to use default state management.

public class SamplePublicationEntity : IKafkaPublicationEntity
{
    public KafkaPublicationState KafkaPubState { get; set; }

    public DateTime KafkaPubNbf { get; set; }
}

Create publication handler derived from DbContextEntityPublicationHandler<TKey, TValue, TEntity, TContext> for entity with default state management or from DbContextPublicationHandler<TKey, TValue, TEntity, TContext> for custom state management.

Setup publication

KafkaBuilder kafkaBuilder = services.AddKafka();
kafkaBuilder.AddPublication<string, KafkaEntity, SamplePublicationHandler>("Sample");
