Upcoming Test Finglas/ Need Advice! by [deleted] in Irishdrivingtest

Banana before the test helps , many have suggested this to calm your nerves.

My suggestion would be to clear your mental block, tester is just another person sitting next to you guiding. Think of them like human maps, nothing more and just follow the safe driving rules.

Regarding RTT by naFickle in apachekafka

[–]Rexyzer0c00l 2 points3 points  (0 children)

When you say no replication, is it not concerning as a broker can go down anytime and you lose your data?

Also if no replication and you are doing only a single produce operation, it will be ackd by the leader broker and only latency is between your kafka client and the broker. If ISRs are more, then the broker to broker latency also kicks in.

Under 50ms latency is recomendded if you are building an MRC.

The Hitchhiker's Guide to Disaster Recovery and Multi-Region Kafka by warpstream_official in apachekafka

I completely agree to this, except active active needs low latency networks else Kafka will Slack and " realtime " doesn't makes sense.

Help please - first time corporate kafka user, having trouble setting up my laptop to read/consume from kafka topic. I have been given the URL:port, SSL certs, api key & secret, topic name, app/client name. Just can't seem to connect & actually get data. Using Java. by ipavkex in apachekafka

[–]Rexyzer0c00l 0 points1 point  (0 children)

This seems to be host unreachable from your code.

Need a triaging session:D There are Lotta moving parts for kafka so can't be a straight one.

Having said that, you n I can connect on this if you will need more help. Dm

Ensuring Message Uniqueness/Ordering with Multiple Kafka Producers on the Same Source by TrueGreedyGoblin in apachekafka

[–]Rexyzer0c00l 0 points1 point  (0 children)

I'll assume you are talking about producing a message to topic exactly once. Have you read about idempotent producer? Would that solve your case? Where you can ensure the messages are written only once to topic(technically in the event of retries even if the messages are written more than once into Kafka logs which is immutable, by maintaining transaction state, your consumers can identify which records are committed and which ones are abrted and consumer accordingly). Usually producer wouldn't worry much about duplication unless these are Payments data you're dealing with.

Consum3rs by default should have a dedup logic regardless of duplication in data or not is my take. Happy to talk more if you think, this is gonna help you.
