This blog post explains the end to end implementation of the Bully Algorithm which is a leader election algorithm in Distributed Systems.
A distributed system is a collection of independent computers that appears to its users as a single coherent system.
These multiple nodes are physically separate but linked with…
Assume that your actual Rest API gets a number of identical hits, but actually that Rest Endpoint expects only one hit in order to proceed with the rest of the work!
How to handle this?
In Python, we can handle the scenario by developing a proxy.

We can invoke APIs using a request payload or sending them in the URL as query parameters.
We can do several operations using the property mediator with the query parameters.
We can check this using a simple property as below. Assume my URL is as below. We can check if…
Using WSO2 Enrich mediator
Assume we need to copy a whole message context to a property for further use. As an example, if we use Amazon SQS Connector, we may need that message to send it to a Queue as the message body, but we need to pass it as…
By default XPath 2.0 functions are disabled in WSO2 EI. In this post, we will look at how can we use them in EI 6 and EI7.
We can build messages via sending parameters in the URL or as a payload as a POST request. In both ways, we can build a customized message using Payload Factory.
