Chetan Mehrotra commented on OAK-4640:
--------------------------------------
Document once added cannot be constructed back as is. For now I do not think
that in memory state consumed by such documents would be large. Further
LuceneIndexWriter can do this on best effort basis i.e. if total number of
documents accumulated for given commit exceeds say 100 then do not do that and
let documents be created on observer side. This might be the approach for large
transaction
> Provide a way for commit hook to record meta data for a given commit

>
> Currently as part of commit the caller can provide a CommitInfo instance
> which captures some metadata related to commit being performed. Note that
> CommitInfo instance passed to NodeStore is immutable.
> For some usecases we need a way to add some more metadata to on going
> commit from within the CommitHook
> * OAK-4586 - Here we need to record nodetypes of nodes which got modified as
> part of current commit
> * OAK-4412 - Here we want to generate Documents for modified nodestate (per
> index definition) and "attach" it to current commit
> This meta information would later be used by Observer.
> To enable such cases some mutable state needs to be exposed as part of
> CommitInfo which can be used by CommitHooks.
> As per discussion of DL [1] this can be done by adding a new
> {{CommitAttributes}} instance which can be accessed from {{CommitInfo}}
