SQL databases' implementation of relations varies a little but are mostly a combination of two different underlying data structures: theheap fileandb-trees. Consequently the operation times are generally logarithmic - meaning that they grow slowly as the size of the data-set grows. The rest of t...
there are only a few articles that explain how a database works. You can google by yourself “how does a relational database work” to see how few results there
The target or targets is the new index (or heap) or a set of new indexes that is being created or rebuilt. User insert, update, and delete operations to the source are applied by the Database Engine to the target during the index operation. For example, if the online index operation ...
Heap overflow: It occurs when the memory allocated dynamically by the program exceeds the heap size. A heap is a first in first out (FIFO) data structure used to store data that is required for a long time during program running. When the heap overflows, even if the program does not st...

So i can be alerted when a service stops running? Domain Admins lost administration permissions on Domain Controllers Domain Controller bind errors...
The heap is a memory structure used to managedynamic memory. Programmers often use the heap to allocate memory whose size is unknown at compile time, where the amount of memory required is too large to fit on the stack or the memory is intended to be used across function calls. Heap-based...
Sincelibcollector.sowas not in the target address space when the process started, any data collection that depends on interposition on user-callable functions (synchronization tracing, heap tracing, MPI tracing) might not work. In general, the symbols have already been resolved to the underlying fu...

how does malloc/free work? Here is the answer I got from Internet. Here's a simple, vague answer: Your process has a region of memory, from address x to address y, called the heap. All your malloc'd data lives in this area. malloc() keeps some data structure, let's say a list...
