C++ Where integer read turns into a function call

Looking at compute-intensive languages like OpenCL, that targets modern GPUs among others, one can observe that the most local (private or thread / work-item local) memory is the fastest and the more general it is the slower memory access gets.

Advantages of using columnar storage for logs

Traditional solutions for logs are row based and have a reverse index that allows for fast retrieval of records based on search terms. Recently, it is becoming more and more common that analytical databases with columnar storage are being used for storing and processing logs.
