Thomas Mueller commented on OAK-3694:
-------------------------------------

An alternative to this approach, the following algorithm works and does not require Oak changes. Also, it works with multiple async index threads (async, async-fulltext,...):

* Create a node with a random name and text, for example "/tmp/test-3ee3fafa-3aee-4402-ac9c-3895bccc85ef", with properties for each sync index type, for example "content" = "3ee3fafa-3aee-4402-ac9c-3895bccc85ef" and "desc" = "3ee3fafa-3aee-4402-ac9c-3895bccc85ef".
* Search for that node using a query that uses the async index, if not successful wait one second retry until timeout
* Search for that node using a query that uses the async-fulltext index, if not successful wait one second retry until timeout
* Delete the node

> 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).
