             Summary: Expose the preferred transient space size as repository 
descriptor 
                 Key: OAK-1356
                 URL: https://issues.apache.org/jira/browse/OAK-1356
             Project: Jackrabbit Oak
          Issue Type: Improvement
            Reporter: Tobias Bocanegra


The problem is that the different stores have different transient space 
characteristics. for example the MongoMK is very slow when handling large saves.

suggest to expose a repository descriptor that can be used to estimate the 
preferred transient space, for example when importing content.

so either a boolean like: 
  {{option.infinite.transientspace}}

or a number like:
  {{option.transientspace.preferred.size}}

the later would denote the average number of modified node states that should 
be put in the transient space before the persistence starts to degrade.
