That's a great reply! Solving problems with different approach and finding out which one is efficient is a good way to learn and reason about. Thanks!

Does the book also talk about using different algorithmic techniques for a certain problem set and goes to the depth to explain why certain algorithm is best suited for certain tasks? Do you also explain about the Time complexity in Big O notation?

Thanks for the reply! Those topics around competitive programming seems interesting!

I agree with you, it is about thinking in terms of algorithms, but nevertheless I wanted to find out if the book takes an imperative approach or a functional approach to implement the algorithms!

Which programming language is used in this book? Is it C?

Interesting book! Where do I find the ToC? The Amazon link seems not to have it,

How is this book different from the Grokking Algorithms one?

Does this book talk about scripting deployment of a Kubernetes cluster? For example., using Terraform scripts, I can specify a barebones k8s cluster and by the execution of this script my k8s cluster can be set up on demand on any cloud provider. does this book address this?
I'm contemplating using Spark SQL for some of my data needs. I have a Python codebase that uses the Pandas library. I guess if I were to migrate that to a Scala codebase, I need something similiar to Pandas and I guess Spark SQL could be that. Now my question is, can I use Spark SQL without a Spark server? If yes, then I see Spark SQL as an alternative to Pandas. If not can anyone suggest me some good library to work with a Pandas kind of a library in Scala?

I have been reading through some blogs on getting to know myself better on this promising technology. I'm astonished that there is a book already on this. It is interesting.

I had a look at the ToC of this book "The Business Blockchain" but it does not look like a technical book, but rather a very quick overview of what Blockchain is. Is there a reason why this book was kept simple this way? I was expecting some sample applications where I could use Blockchain (using Etherum or IBM's HyperLedger)

I figured it out by myself. Here is what I had to do:

I have a client that I generate using the WSDL that I have. When I tried to connect to this WebService, I get the following error:



The actual server that hosts the WebService expects a SOAP message that contains the security header like:



How to get this along with my SOAP message that gets generated when the request is made? This is what I do in my code to call the WebService:



Any suggestions?

Welcome to Javaranch and Congratulations on your certification!
This is a perfect timing. We are containerising our Microservices with Docker as a first step. We want to add redundancy to all our Microservices as a next step. We are looking at all possibilities and this looks interesting thing to do with Kubernetes.

So I have got a couple of questions:

1. Can I create a Master / Slave kind of an architecture with Kubernetes? Say I have Microservice A running as a Docker container. Can I have Kubernetes manage this as a Master and have 2 or 3 other instances as slaves?

2. If the Microservice A is exposing ports, how would this behave with rudundancy? Should I have multiple ports open?
