In a system design interview, you will be asked to design a complex system, such as a website, mobile app, or network infrastructure. The interviewer will evaluate your ability to decompose the problem into smaller subproblems, make trade-offs between different design decisions, and consider the scalability and performance of the final solution. Th…
In Apache Spark, you can cache a DataFrame in memory using the cache() or persist() method. The cache() method is a shorthand for persist() with the default storage level of MEMORY_ONLY. You can use the persist() method to specify a different storage level if desired, such as MEMORY_AND_DISK or MEMORY_ONLY_SER.…
Why develop apps when you can create "social apps" without coding as side projects.
The n-queens problem is a well-known problem in computer science and mathematics that involves placing n chess queens on a n x n chessboard such that no two queens are able to attack each other. This means that no two queens can be placed on the same row, column, or diagonal. The problem can be generalized to other chess pieces, such as the n-rooks…
The time that it takes computers to process information.
Consistent Hashing is a distributed hashing scheme that operates independently of the number of servers or objects in a distributed hash table by assigning them a position on an abstract circle, or hash ring. This allows servers and objects to scale without affecting the overall system.
