It boils down IIUC, that only the readers that where involved during a commit would have to be re-calculated if getDocumentNumber is called, right?
to be precise the UUIDDocIds that refer to readers that were involved in a commit need to be re-calculated. There are two occasions where the document number needs to be recalculated:
- the parent node is modified, which means it re-indexed and effectively is deleted from the index and added again. modifying a node always means that it 'travels' from an old index segment to a younger one. this might actually give use some optimization potential when we need to get a document number again in a UUIDDocId.
- index segments are merged. again nodes travel from older indexes to a younger one. hmm, did I miss anything? regards marcel
