Based on the klepto docs

...ANSWER
Answered 2021-Feb-28 at 18:38I'm the klepto
author. Sorry the docs are not clear there. If you look at the line above (i.e. line 158), you'll see that the table name is set with the keyword name
... which then gets split into the db
name and the table
name. I guess I could throw a better error when table
is given as a keyword argument.

QUESTION
I'm getting a memory error when trying to pickle a large numpy array for a deep learning problem shape: (7451, 1500, 1500, 1))
. That stated, I see a few posts on klepto
and read the docs but I'm not sure how to actually use klepto
to save as a pickle file.
Can anyone break it down to a fifth grade level for me?
This is throwing the memory error:

I've created a klepto dir_archive.
On subsequent archive access, how can the archive keys be determined without loading the entire archive into memory?

QUESTION
I'm using Klepto archive to index specs of files in a folder tree. After scanning the tree, I want to quickly remove references to deleted files. But simply removing an item one-by-one from the file archive is extremely slow. Is there a way to sync the changes to the archive, or delete multiple keys at once? (The 'sync' method only appears to add new items)
The helpful answer by @Mike Mckerns to this question only deals with removing a single item: Python Saving and Editing with Klepto
Using files.sync() or files.dump() appears only to append data from the cache, not sync the deletes. Is there a way to delete keys from the cache and then sync those changes all-at-once. Individual deletes are far too slow.
Here's a working example:
...ANSWER
Answered 2019-Feb-15 at 22:05I see... you really are concerned about the speed of deleting one entry at at time from a file_archive
.
Ok, I agree. Using __delitem__
or pop
on a file_archive
is a bit brutal when you want to delete several entries. The slowdown is due to the file_archive
having to load and rewrite the entire file archive for each key you delete. This isn't the case for a dir_archive
or many of the other archives... but for a file_archive
it is. So that should be remedied...
UPDATE: I've added a new method that should enable faster dropping of specified keys...
