Hi Sir, Can you create a series on Transaction management. Thanks

Very helpful.. Could you please start Spring Core series ? I see you have Spring Boot playlist, but if you can start Spring Core it will help a lot for junior developers.. Thanks in Advance :-)

[@sureshg1]

Thank you for sharing.
This interview should be labeled as Java/Spring Expert not just API developer. What was the result ? Are the questions from one interview or collated from multiple ?

[@pratapjavasingh3239]

Please upload same way logical questions that's enough for interview as experience level

[@GauravSharma-up9gs]

Please make video .

[@satyanarayanajammala5129]

answer for 4th question is not much clear. Could you give clear example

[@kxpala2]

You could write a new 3rd micro-service that does one of following
1. connects to both datasource to fetch data
2. connects to both microservice(1st & 2nd) to get data and consolidates it
3. For table level joins we can consider DB Link as well
Its all depends on db design and specific use case.
