Wail Y. Alkowaileet updated ASTERIXDB-3374:
-------------------------------------------
Description: The buffer cache's pin, unpin, and write operations are not
exposed to the context of the overall on going operation. To some extent, the
pin operation have some context (e.g., not incrementing a stat). Changing the
buffer cache interface every time we want to incorporate contextual information
is not sustainable. Instead, a user of the buffer cache should provide a
context object that can hold all the necessary information of a given buffer
cache operation (e.g., incrementing stats or processing the header when reading
a page in a pin operation). (was: The buffer cache's pin, unpin, and write
