\subsection{Cloud-Native Databases}
|
|
Many of the traditional database engines may run into overhead due to heavy I/O traffic, especially when mirroring.
|
|
|
|
As a result, many companies have improved implementations of SQL databases to make them suitable to cloud infrastructure.
|
|
|
|
Some of the improvements include caching. Micro-partitions in the Snowflake system is a system to facilitate query processing.
|
|
Each one of these partitions has sizes between 50 and 500 megabytes, and has metadata describing what is inside, which can also be read without reading the entire partition.
|
|
|
|
Furthermore, Amazon S3, the storage platform, does not support in-place updates, files are replaced in their entirety.
|
|
This means that old data can easily be recovered.
