How to disable transaction log feature in zope

Hi,

It seems that lot of system resources are getting consumed in zope because of its transaction log feature. Ff course it has got its utility in undoing some mistakes.

How this feature can be disabled in zope.

regards,

Kedar

Hi

thanks for your response.

I am referring to http://<IP>:<port>/manage_UndoForm . Is there a way where by I can configure zope not to have this logging feature.

regards,

Kedar

What is consuming resources? If you don't need the undo form, just don't
use it.
Otherwise where should be a performance impact during standard Zope
operation.
Please explain!

Let us keep this performance/ maintenance issue aside. is there a way where by this feature can be disabled so that zope does not log this at all.

The standard FileStorage backend for ZODB and Zope is an append-only
database. It would not be possible to remove the append-only nature
without a complete redesign of FileStorage. I doubt anyone wants to
take that on.

There are alternatives to FileStorage, however. For example, I've
tinkered with a version of RelStorage that does not save any history.
It seems to work well, but I haven't released any history-free version yet.

The standard Zope installation runs on top of the ZODB FileStorage,
which provides this fetaure. The resource consumption (disk space) can
be mitigated by packing the storage frequently, which removes the older
records.

You can run other applications on top of Zope (e.g., using relational
data), which won't impact it. There used to be ZODB storaages which
were "packless" or which did not support undo: AFAIK, none of them are
supported any longer.
