Apache Pulsar Async Consumer Setup (Completable Future)

Asked 2021-Apr-22 at 22:55

I am trying to setup an asynchronous consumer for Apache Pulsar, but my problem is only 1 message is received and no other messages come through unless I restart my Spring Boot application. Unfortunately, the documentation around using the CompletableFuture with Pulsar is not great and I am new to using them.

My code below:

In order to prevent such excess memory consumption, you will want to add an intermediate data structure to your class that limits the number of outstanding CompletableFutures such as a LinkedBlockingQueue as shown below

Is it possible for a producer to know if a message was acknowledged?

Asked 2021-Mar-29 at 15:13

Topic says it all.

My guess is that the delivery guarantees of Pulsar make this question nonsensical but I would like to know for sure.

Generally speaking, producer shouldn't know about consumer's actions - this is the whole point of introducing message brokers between two parties. Pulsar can guarantee that message will be residing in the topic until all subscriptions acknowledge it.

Saying that - to accomplish you goal you need to have a pair (producer-consumer) on each side and pair of topics, once message is consumed, another message is sent with the notification about successful consumption.

To be able to achieve guarantees that both acknowledge and sending confirmation to another topic happen together or not happen together you need to use transactional API that Pulsar provides, both those actions should happen in one transaction

QUESTION

Message Brokers - Multiple consumers with this same client ID

Asked 2021-Mar-23 at 08:32

I've been considering some multiple consumer problem with my system and unfortunately I'm really stuck. I mean - I see some solutions, which are below, but they are propably not enought efficient. Let me introduce system:

User has their specific Id. User can be logged on diffrent devices - many mobiles, many browsers in this same time. When user is offline every message which user has got should be provide when user is online. When user is online, should be kept informed on a regular basis about messages. Every user, when is online is connected by WebSocket.

So I have been thinking about message brokers from this pool - rabbitmq, kafka, apache pulsar ( All system above will be in Java ). And this is my thoughs about this:

Rabbitmq - Every device gets their own queue associated with client Id. But here i see some troubles. For example - user gonna log in 4 browsers and each will get new queue ( of course I assume that some not used queue will be deleted after time but this solution can be overloaded if somebody just wanna do this ).
One queue with marker for every user which messages were consumed - I tried implement this with apache Pulsar but my every attempt was running out with created new consumer (not continue as the same consumer) - Maybe I can't use this API?
Apache kafka - groups and partitions? Its similiar to point 1.

I will be really gratefull for every single hint - If You see some better solutions with other technology just let me know - I will adjust to this.

( If it matters - Java and SpringBoot are core of this )

ANSWER

Answered 2021-Mar-23 at 08:32

I can respond for the apache pulsar part - you need to set SubscriptionName in consumer to be equal to your UserId, this will ensure messages to be consumed starting from the last acknowledged one for that user.

QUESTION

Apache Pulsar Clickhouse Sink - does it have intervals between inserts?

Asked 2021-Feb-06 at 19:11

Clickhouse allows high performance writes but only if they are done in bulk and with intervals (recommended is at least 1 second interval between inserts). In the documentation to JDBC connector for Clickhouse batchSize option exists but there is nothing about intervals between inserts and I didn't manage to find insertion logic in the code (I am not a Java guy though).

Does it mean there are no intervals and Pulsar simply does inserts as frequently as it can?

...

ANSWER

Answered 2021-Feb-06 at 19:11

I know nothing about Pulsar.

recommended is at least 1 second interval between inserts

That recommendation is "one insert per second". Nothing about 1 second to sleep.

This recommendation is too basic and very vague.

Every project is unique, has own environment and requirements.

In one project I insert 10mil. very wide rows per minute with RAID 10 with HDD disks.

In another project I do 1000 inserts with ~100 narrow rows each per second using In-memory parts with single NVME disk.

ANSWER

Answered 2020-Jul-24 at 14:00

The error message you are getting is coming from Log4J 1. This indicates Log4J 2 isn’t being used, which would explain why it can’t find the pulsar appender.

If you want to use Log4J 2 you need to re-examine your dependencies.

This also indicates it isn’t using your logging configuration.
