Most sensible video on Kafka topic, thank you very much.

Dear Vishal, Thank you for your effort & time to produce & upload these tutorials.

[@javatechlearning]

Thanks a million

Nice video bro. It worked for me. One quick question for you: How to run query like this: select id,CUST_LN_NBR FROM flex_activity limit 1; In this query I am using limit option in due to that it is getting failed. If I use simple query without limit then it works fine: Error I am getting: org.apache.kafka.connect.errors.ConnectException: java.sql.SQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE `ID` > -1 ORDER BY `ID` ASC' at line 1 This is not only with limit option, this is for all whenever you have to apply any filter.

[@resam32]

Thank for the great tutorial. Did you have to create the avro schema or it gets generated?

[@resam32]

nvm, I found the ans from the video.

[@ttc744]

Very helpful video. I see the 'timestamp.column.name' should have been TXN_DATE (as flashed up on video) otherwise update wont work. It would have been nice to see this working at the end in addition to adding new records

Hi Vishal, I am facing issue Invalid connector configuration: There are 2 fields that require your attention while connecting to mysql db ..is this required mysql jdbc configuration as well ? if yes how we can do that ?

Hi, Vishal , Could you please help me in pushing confluent topic data into scylladb table...

[@krushnapardeshi3694]

I'm beginner on kafka and DB concepts. What is dialect exactly in this case ?

[@nareshkyv]

Hi Vishal thanks for sharing videos. Please let me know where can i check the errors/logs when connectors failed? also logs/errors if any issues in processing data. Please share me paths

[@javatechlearning]

Where is your confluent server running? On local or confluent cloud?

[@ibnu0muhammad]

Really cool bro!

[@oyeyemirafiuowolabi2347]

Please, what is the best method or connector available to pull or ingest data that normally get updated or changed. For example bank accounts statement. Thanks.

[@javatechlearning]

It depends where the data is present. Kafka provides range of connector to source data. In special cases we could implement our own connector too

[@oyeyemirafiuowolabi2347]

@@javatechlearning If the data is present in a legacy application table that has no column for timestamp. In this case, how can we ingest the records anytime there is update to the already ingested record. Thanks.

Could you please do a Video loading tables into their respective topics for each tables , using SQL SERVER as a source??.... so everytime each table suffers a DML action the new event s sent to the Confluent plataform..

[@carlaguelpa4574]

Hi Vishal, thank you very much for this! :) I have 1 question, how do you installed the connector plugin for sink ?

[@javatechlearning]

Hi, thank you very for your positive feedback. I have installed it using confluent hub command which you can use from the place where I downloaded confluent bundle

Hey, i tried to connect to postgreSQL and was finally landing with below error in logs Caused by: org.apache.kafka.common.errors.SerializationException: Error serializing Avro message Caused by: org.apache.kafka.connect.errors.DataException: Failed to serialize Avro data from topic any help ?

[@javatechlearning]

It seems your not using right avro schema to read events from topic. Try comparing topic data samples with your schema

Hi Vishal, Could you please help me with Snowflake Source connector via (JDBC) to unload the data to Confluent Kafka. If there's any sample code please share me the github details.

[@mdicopriatama6380]

hi Vishal, when i want to upload the connector i faced the issue "invalid connector class" i need advice. thanks

Hi Mirza did you find the answer for "snowflake as source connector"??..if yes please let me know the info.

[@akshatkhandelwal6384]

Can you please guide me how we do this in local instead of confluent cloud? What I want to do is like to connect database with kafka connect and the data gets inserted into kafka cluster

[@javatechlearning]

I did it in local itself. I'm not using confluent cloud

[@akshatkhandelwal6384]

@@javatechlearning I meant like you used confluent centre right.....What I am trying to do is run zookeeper, kafka from command line then I am stucked like how we can connect database to kafka, I saw some tuto they all are confusing do I need system registry or anything?

[@javatechlearning]

Sorry I couldn't follow you much. Confluent center gui is only for monitoring purpose. Main servics are connect, schema registry, Kafka, zookeeper etc. They all should be started in order to connect database

My Confluent installation dont have JDBC source connector by default , Please help me how to install ?

[@javatechlearning]

Hello, you need to install jdbc connect plugin using confluent hub

[@javatechlearning]

You can find command in my video

[@sandeepravitej4583]

@@javatechlearning Thanks for your time figured it out , my source connector is up now ..would it be possible to make a video on how to read from mysql and write into mongodb ? or you can share any known sources which speaks about it

[@javatechlearning]

You first need to build jdbc source connector to read MySQL data and then one sink connector to sink topic data to nosql db

Thanks for the video , Vishal. I wanted to know that , we can also source Oracle DB using JDBC Source Connector too, isn't it? And where did you deploy the connector config file? In the Confluent cloud?

[@javatechlearning]

Source Oracle db to Kafka topic is done by jdbc sink connector. Answer to second question I deploy using control center on local machine itself. Watch my installation video
