THEORY: Distributed Transactions and why you should avoid them (2 Phase Commit , Saga Pattern, TCC, Idempotency etc)

Distributed Transactions and why you should avoid them

  1. Modern technologies won't support it (RabbitMQ, Kafka, etc.);
  2. This is a form of using Inter-Process Communication in a synchronized way and this reduces availability;
  3. All participants of the distributed transaction need to be avaiable for a distributed commit, again: reduces availability.

Implementing business transactions that span multiple services is not straightforward. Distributed transactions are best avoided because of the CAP theorem. Moreover, many modern (NoSQL) databases don’t support them. The best solution is to use the Saga Pattern.

Create a private fork of a public repository

The repository for the assignment is public and Github does not allow the creation of private forks for public repositories.

The correct way of creating a private frok by duplicating the repo is documented here.

For this assignment the commands are:

  1. Create a bare clone of the repository. (This is temporary and will be removed so just do it wherever.) 
    

    2. 



git clone --bare [email protected]:usi-systems/easytrace.git

HOWTO: Clean Up Nomad Data Directory


Issue


When attempting to remove all of the data in the Nomad data directory, several directories and files are unable to be deleted.  Many messages are logged to the console like:


rm: cannot remove ‘alloc/736f61b9-d7dc-cb73-0dd1-76b1b2ba032d/nomad-ui/secrets’: Device or resource busy
rm: cannot remove ‘alloc/ddcf5a78-5497-f4a4-a101-221fc4e0180b/fabio/alloc’: Device or resource busy
rm: cannot remove ‘alloc/ddcf5a78-5497-f4a4-a101-221fc4e0180b/fabio/secrets’: Device or resource busy
