Marcel Reutegger commented on OAK-10147:
----------------------------------------
bq. Sessions needs to be closed, and all objects obtained from the session need
to be garbage-collectable?
Yes, in this case the memory would be released.
> Many move operations may consume a lot of memory

> Key: OAK-10147
> URL: https://issues.apache.org/jira/browse/OAK-10147
> Project: Jackrabbit Oak
> Issue Type: Task
> Components: core
> Reporter: Julian Reschke
> Assignee: Marcel Reutegger
> Priority: Major
>
> We have encountered an issue where a component did a huge number of move
> operations in transient space, and oak-core's "MutableRoot" class consumed
> ~800 MB for ca 3000 move operations. This seems to be a lot.
> We should:
> 1. Write a test / benchmark that reproduces the issue
> 2. Check whether it's specific to a certain store implemention
> 3. See whether the memory footprint can be reduced
