Need help with kafka. Im really new to Kafka and i just started learning.
I'm getting this issue when I'm following a tutorial.
Package org.apache.kafka.clients.producer does not exist.
I'm using NetBeans if that gives any clues.
Any clues and help is very much appreciated.

I am trying to deploy my contract to Matic/Polygon main net and am running into the error "only replay-protected (EIP-155) transactions allowed over RPC". This is my network settings Network Settings . Same contract deploys perfect to Ethereum Rinkeby test net so I know it's not a contractual error. I have tried all the public matic RPC's and all result in the same error and I can not seem to find any info online about using Brownie to deploy to Polygon other than that is EIP-155 has to do with the deployment of the same code to multiple chains at once. Any help will be greatly appreciated.
For anyone who comes to this problem as well, I ended up solving it by uninstalling all brownie related files and re-installing and that did the trick for me. Hopefully that helps y'all.
Im following this tutorial to set up a simple nodejs in docker with the help of sails. So far so good, but I keep getting this one error that it cant start the app because it misses a hook('userconfig'). I cant post the image due to a reputation below 10, so here is the link to it. https://imgur.com/a/wTYr8N8)
The versions i use are:
sails: 1.1.0
sails-mongo: 6.5.0
I’m a student and i’m working on my last year project, the project is about Data warhousing, BI, etc...
So Im asked to work with Apache Kylin
I did some researchs about it, learned some
And I looked for if it is possible to use a PostgreSQL as Data warehouse and make it communicate with Apache Kylin to build cubes
But found nothing...
So would you please answer to my following question:
Is it possible to make the apache kylin communicate with a postgreSQL DWH?
And if there is some hidden documentations about it would you please share it?
Time is running guys and i really appreciate your answers and guides
Thanks in advance.

It's doable. Kylin provides data source adapter for JDBC data sources. PostgreSQL could be one of the data source adapters. MySQL is supported by default. You could check this link to learn more: http://kylin.apache.org/development/datasource_sdk.html
