Re: Question on how Geode handles data on Disk

I agree its kind of academic but any answers will be appreciated, I just
wanted to understand the performance characteristics when using disk
persistence

What I meant here "Also if I request data for ID 1 will it bring it only
from disk or " was that if I request a tuple which is not in memory and is
in disk,
  1) How does Geode know its in DISK
  2) Does it bring only that tuple (value) to Memory or brings the whole
page

Question on how Geode handles data on Disk

[Amit Pandey]

Hi Geode Devs,

How does Geode handle data on disk ? How does Geode mark that some data of
a region is in disk , is it basically what we call as the Tombstone
approach ? Also if I request data for ID 1 will it bring it only from disk
or

Secondly, how does Geode handle updates of data on disk ?  SO does it
discard the data on disk when it brings a tuple in memory and writes a new
file to disk ?

Regards
