I've come across something that I've always taken for granted because "it just works".
I have a 512 byte page blob that's been previously written to Azure. Now I want to modify just one of the bytes in it, but leave the rest of the information in tact. What's a good strategy for doing this?
When I was thinking about this problem I realized that hard drives do all of this for me; this is what I've been taking for granted. Data is stored in a sector, yet I am able to modify certain parts of that sector while leaving the rest of the data as-is.
I'm honestly not even sure what this kind of data access is called. I'm assuming I need to load the entire blob into memory, modify the bits I want and then write the 512 byte blob back, but that seems like a naive approach.
Thanks for any information
