SPIKE: Adding ActiveMQ in project.

[evtushenko-sasha]

Estimated time spent 8 hours.

The result of this spike will be finding the best strategy of message exchange between rest-api and rest-client for adding tags and comments, exploring activeMQ, how to install, how to create queues, etc.
exploring Spring JMS.

Notes:

1. What will be result of this spike? POC, MVP, thesis and general strategy of message exchange?
2. Estimation time for researching?
3. Please specify what kind of application will work through JMS, e.g. adding tags just through JMS, but reading list of tags using HTTP to REST-API.
4. Are you going to use back pressure mechanism? E. g. if comment has been successfully added then queue send message OK.

Updated.
4. Yes, this is necessary for the stable operation of the application. Since the error on the server, the user must know that the content that he added was not saved.
