Let’s say you have a URL which needs to send an email address as a query parameter. If you create a standard REST API within WSO2 ESB (or EI) and try to match the query parameter in uri-template, it will fail during the execution time. As an example, if you have the below API definition. <api xmlns="http://ws.apache.org/ns/synapse" name="EmailAPI" context="/voice"> <resource methods="POST GET" uri-template="/details?email={email}"> <inSequence> <log level="full"> <property name="EMAIL" expression="$url:email"/> </log> <respond/> </inSequence> </resource> <resource methods="POST GET" uri-template="/phone/{number}"> <inSequence> <log level="full"> <property name="PHONE" expression="$ctx:uri.var.number...

When it comes to message broker solutions, those can be categorized into 2 main types Standards based traditional message brokers (e.g. Apache ActiveMQ, RabbitMQ, WSO2 MB, Apache Qpid) Proprietary modern message brokers (e.g. Apache Kafka, Kestrel) Based on your requirement, you need to select the best category and then go for a specific vendor based on your needs, IT capacity and financial capabilities.
