>
> The memory usage of an in-memory commit currently depends on the number of
> modified nodes and the structure of modified documents. The first is limited
> by the updateLimit on the DocumentNodeStateBuilder. When the updateLimit is
> reached, the changes are pushed to a branch. The structure of the modified
> documents comes into play, when those documents have a rather high memory
> usage. The current commit implementation performs the update in a single call
> to {{DocumentStore.createOrUpdate()}}, which has a return type of
> {{List<Document>}}. The returned list contains the documents as they looked
> before the update. With a default of 100'000 as the updateLimit and heavy
> weight modified Documents, this can result in a high memory usage.
