Let's say we have a table like with just an integer primary key named ID
and a text column named VALUE…


if we set value to 0, "hello world"

… obviously , that's a normal value.

However, what happens if we update it with

0, null

… how is the 'null' stored?

I couldn't find any documentation for this anywhere.

The new null supersedes the older value of "hello world" so I assume it has
to write it into an SSTable before both SSTables are compacted.
