Possibility of read/write with transparent compression #8

Closed ruanformigoni closed 1 year ago

ruanformigoni commented 1 year ago

Hey there,

I want to modify the project to support writing with the transparent compression aspect, do you think that it would be feasible?

Thanks.

For write, compression is the least thing you need to bother.

The write path needs a lot of things like delayed-ref infrastructure.

My current objective is to make the code base small and mostly for bootloader port.

Thus write is not a high priority.

If you really want to implement the write support, I'd say you can go porting the btree COW code first, then delayed-refs, and the extent reservation part first. But overall my estimation is, the write path would be 3x the number of lines, thus not really worthy.

Thanks for the pointers. I'll give it a shot :)
