Valentin Olteanu commented on OAK-3694:
---------------------------------------

[~chetanm], as discussed during the oakathon, I've updated the story with the requirements. Thierry had proposed a solution on OAK-3606, but please comment with any idea that you have on this. 
It would be really helpful to have this done in a reliable way. 
Thanks!

> As a user, I want to know when a node that I've created has been indexed so that I can start using it.
> Generalization: As a user, I want to know when everything created before timestamp T0 has been indexed. 
> Ideal solution: MBean operation {{bool isIndexedBefore(long timestamp)}} that returns {{true}} if everything created before {{timestamp}} has been indexed (by all indexers).
> Current options: 
> # check IndexStatsMBean for Start and Done to determine if a cycle has started after adding the node and has finished. Issue: there can be multiple async indexers. OAK-3606 proposes a solution.
> # add a node and search for it until it is retrieved. Issue: must add different nodes for different indexers and wait for all. 
> These options are not precise (give false positives) and are not resilient to changes in indexing strategy (e.g. adding one more indexer breaks the checks).
