What are microservices

The following are my own understandings of the topic


 Microservices are like small functionality of a program.

Examples of microservices are "User registration", "Movie ticket", "Seat booking in theatre". 

The advantages of microservices are: 

- Development process made easy. For example, deploying, testing and reusing of code. Also requires less development time


The disadvantages of microservices are:
- Impacts performance. For example, latency when heavy use, extra communication between services.

- Requires additional work to deploy. Because the microservices need additional management, control and security needs. Also requires complex testing.


To describe metaphorically :

Think of a team of people who are doing the same work, if you want to change the design of the work, you would need to inform everyone and everyone would need to change the design. If you distribute the work to different people, then you can just order the person who is responsible for that particular work to change the design. So you do not need to get everyone involved.







For my own reference.

The pattern here is:
- When development is made easy, additional management is required when you deploy the application.

Running CQL scripts in Cassandra

How to run CQL scripts in Cassandra  There are 2 ways to run a CQL script, the first way would be running the following command: - cqlsh -f {directory} The second way would be using the command within the CQLSH terminal: - source '{directory}' Where does the {directory} points to? The directory points to the root of your server. For example, if you are on linux, the root would be `/`. Therefore, if you placed your scripts under the folder `scripts`, your directory would look like this `/scripts/{cql_script_name}.cql`.  I've been running the command, but it keeps saying `No such file or directory`? If you met this error, please make sure that:      - The file actually exist in the directory. You can check if by typing `ls -l {directory}`. If it doesn't exist, it will show the same error. If you are on docker, and you are unsure of how to mount your CQL file into your container, you can check out this guide.      - The CQL file has the correct exten...
