Microservices have become a popular architectural approach for building large-scale, complex systems. While asynchronous communication is often preferred in microservices, there are cases where synchronous communication is necessary. However, relying on synchronous communication introduces challenges related to resilience. This blog post will explore patterns that help make synchronous communication in microservices more resilient, ensuring system stability and fault tolerance.

Fragmentation is a common concern in some database systems. Highly fragmented tables can affect performance and resource allocation. But reducing fragmentation often involves rebuilding the table completely. This blog post will discuss fragmentation and its impact on InnoDB. What is fragmentation? We say that something is fragmented when it is formed by parts that are separate or placed in a different order than the natural one.

Performance is one of the essential aspects of a database management system. Very little can be more annoying and frustrating for users than poor performance, meaning long-running queries and high response times at the front end. One of the most effective ways to tackle performance improvement is having the proper indexes for the table columns. An index can save a lot of time in data access and lead the queries to gather the results the fastest way possible.
