If you use an agile methodology, you must have heard about daily meeting or standup meeting. It’s a regular meeting where each member of the team will share their updates of work while standing.

The discomfort of standing for long periods is intended to keep the meetings short.

There are 3 questions that usually followed for standup meetings

  • What did you do yesterday
  • What will you do today
  • Blockers if any

What is the problem

I had followed the 3 questions above as a format for the standup meetings. Sometimes, the information shared during the meeting may not be relevant to everyone. For example…

Why is it so slow???” One of the top reasons for slow performance in backend is N+1 query. It is a query to load the main model and N queries for loading the associated model, inefficient query, and a common performance anti-pattern.

It is much faster to issue 1 query which returns 100 results than to issue 100 queries which each return 1 result.

Let’s take a look at this example with rails active record. Let’s say you have two tables on your DB, cars and variants, where an entity in cars can have many variants.

Constructive feedback is providing comments or suggestions that contributes to a positive outcome, a better process or improved behaviours.

Elasticsearch, “you know for search”, is a well known search engine with RESTFUL HTTP interface. It’s fast, scalable, and easy to use. Elasticsearch is built to be always available and scale with our needs.

It’s hard to design the perfect elasticsearch setup for the first time. People usually start with the most simple solution that can fit their needs, that’s normal. As your documents and traffic grow, you may need to scale your elasticsearch, especially if you have a performance issue. Here are some tips that you can apply to scale your elasticsearch

Microservice is a famous architecture that has been applied by many tech companies. It enables the rapid, frequent and reliable delivery of large, complex applications, and allows an organisation to evolve its technology stack. It seems to be a good architecture but a too small service can increase the overhead on communications, maintenance, and many more. A service that is too small or fine-grade is called a Nanoservice.

Some people say that Nanoservice is an anti-pattern because of the overhead in maintenance, communication, and so on. Well, It’s not wrong. …
