Let’s assume you are considering using Cassandra for logs storage or in general, for time series storage. You are well prepared - asked google extensively. Yet, there is a trap waiting to kill your cluster in few weeks after lunch.
In the previous post I’ve described a strange problem related to Cassandra Datastax C# Driver which was happening once in the production environment. It’s time to reveal the mystery.
This post will be about my journey with fixing nasty Cassandra Datastax C# driver problem, which took me a lot more time than expected… Can you guess the problem source?
The dark side of Cassandra.
How many timers are in the .NET Framework? What assumptions do they have? Which timer would you use for implementing Speculative query execution?
Warning: this post won’t be about “boring” or “typical” algorithms from Computer Science which we all have learned on studies (like quick sort, merge sort, xxx sort, A*, FFT). Instead, this will be about other little-known, especially USEFUL algorithms, which people working as professional developers should know or heard of.
Normally I “live” in .NET environment. That is, my work is usually related to .NET environment and most popular libraries associated with it. Some time ago, I started to work with Cassandra. Google it. Popular. Superb. Advanced. Supreme. Design for speed and resilience. Used by some big players. That sort of impression you will get. Therefore, just few days after meeting Cassandra I’ve had an eye opener.
