Hi,
Sorry for polluting a bit the thread... =)
I read again how BFS implements it's transactions, and if I understood
correctly, the block cache stores all blocks of a transaction inside the
transaction's list, and then the journal, when writing, simply iterates through
the list to save the blocks. Did I understand correctly?
If so, how can we find the difference between meta-data and data blocks? Or is
this done specifically before we call the block cache (ie. setting a zero
transaction ID when we get data blocks)? When running out of memory, how does
the block cache handle dirty blocks (inside a transaction)?
Hope I understand things a little better now =). Thanks,
Janito
