Karl Wright updated CONNECTORS-999:
-----------------------------------
Description:
The framework currently handles CHAINED models by expecting that reference
extraction take place on all documents with references, regardless of whether
those documents have changed. But a far more common kind of situation is when
a document's references are accurately captured by its version information. It
would be great to perform incremental crawls in this case without doing any
additional reference extraction.
Such a scan would require requeuing of all existing documents, which would make
minimal scans have to process more documents. But this could be a positive
tradeoff if versioning a document was cheap compared to processing it.
Maybe a new class of models, e.g. VERSIONED_CHAINED, might make sense to
consider adding.
