Re: [VOTE] KIP-243: Make ProducerConfig and ConsumerConfig constructors public
+1 (binding), though I still think the Map should be <String, ?> instead of . I also think its better to just expose the defaults as constants on the class. Apparently there was discussion of this before and the concern is that people write code that rely on the default configs and we might break their code if we change it. I don't really buy this as using the constant allows you to to symbolically reference the value rather than making your own copy of it. Usually if we change a default like that there is an important reason why and having the old copied value might be worse than having the value change out from under you. Having the defaults explicitly exposed can also be helpful when writing tests sometimes. -Ewen On Wed, Jan 3, 2018 at 9:30 AM, Colin McCabe <cmcc...@apache.org> wrote: > On Thu, Dec 21, 2017, at 10:28, Jason Gustafson wrote: > > Hey Matthias, > > > > Let me suggest an alternative.

The builder idea would definitely make it a lot easier to configure clients programmatically. I do wonder if there are some cross-version compatibility issues here. If there's any configuration that needs to be set by the client, but then propagated to the broker to be applied, the validation of that configuration really needs to be done by the broker itself. The client code doesn't know the broker version, so it can't validate these configs. One example is topic configurations (although those are not set by ProducerConfig). I'm not sure how big of an issue this is with our current configurations. Another problem here is that all these builder functions become API, and cannot easily be changed. So if we want to change a configuration key that formerly accepted an int to accept a long, it will be difficult to do that.

Re: [VOTE] KIP-243: Make ProducerConfig and ConsumerConfig constructors public
Builders have historically seen some resistance in the project (by some notable original authors...) but they've been increasingly making their way in -- SchemaBuilder in Connect, I believe some small streams APIs, AdminClient stuff. The general trend seems to be towards more fluent APIs. Regarding the KIP, I'm not sure why the APIs are currently Map, but this seems wrong. We have a mess of old Properties compatibility (which we seem to have dragged into the new producer/consumer APIs), but we could at least make these Map<String, ?>. (I prefer just doing Map<String, String> since we go through a parse phase regardless of the types, but didn't manage to make that happen within Connect.) Otherwise, the general idea seems fine to me. -Ewen On Thu, Dec 21, 2017 at 2:28 PM, Jason Gustafson <ja...@confluent.io> wrote: > I didn't sense much resistance in that thread, just an effort to keep the > streams and core client config APIs consistent ;). > > I'd prefer seeing a KIP for a more general improvement, but this change > seems harmless and improves consistency between the clients, so +1 from me. > > -Jason > > On Thu, Dec 21, 2017 at 11:19 AM, Matthias J.

Re: [VOTE] KIP-243: Make ProducerConfig and ConsumerConfig constructors public
I didn't sense much resistance in that thread, just an effort to keep the streams and core client config APIs consistent ;). I'd prefer seeing a KIP for a more general improvement, but this change seems harmless and improves consistency between the clients, so +1 from me. -Jason On Thu, Dec 21, 2017 at 11:19 AM, Matthias J.

Re: [VOTE] KIP-243: Make ProducerConfig and ConsumerConfig constructors public
I personally love the builder pattern idea. There was some push back in the past though from some people. cf https://issues.apache.org/jira/browse/KAFKA-4436 Happy to propose the builder pattern but than we should have a proper DISCUSS thread. Maybe we do this as a follow up and just do this KIP as-is? -Matthias On 12/21/17 10:28 AM, Jason Gustafson wrote: > Hey Matthias, > > Let me suggest an alternative.

Re: [VOTE] KIP-243: Make ProducerConfig and ConsumerConfig constructors public
Hey Matthias, Let me suggest an alternative. As you have mentioned, these config classes do not give users much benefit currently. Maybe we change that? I think many users would appreciate having a builder for configuration since it provides type safety and is generally a much friendlier pattern to work with programmatically. Users could then do something like this: ConsumerConfig config = ConsumerConfig.newBuilder() .setBootstrapServers("localhost:9092") .setGroupId("group") .setRequestTimeout(15, TimeUnit.SECONDS) .build(); Consumer consumer = new KafkaConsumer(config); An additional benefit of this is that it gives us a better way to expose config deprecations. In any case, it would make it less odd to expose the public constructor without giving users anything useful to do with the class. What do you think? -Jason On Wed, Dec 20, 2017 at 5:59 PM, Matthias J. Sax <matth...@confluent.io> wrote: > It's tailored for internal usage.

Re: [VOTE] KIP-243: Make ProducerConfig and ConsumerConfig constructors public
It's tailored for internal usage. I think client constructors don't benefit from accepting those config objects. We just want to be able to access the default values for certain parameters. From a user point of view, it's actually boiler plate code if you pass in a config object instead of a plain Properties object because the config object itself is immutable.
