Thomas Mueller updated OAK-2787:
--------------------------------
Summary: Faster multi threaded indexing / text extraction for binary
content (was: Faster multi threaded indexing for binary content)
> Faster multi threaded indexing / text extraction for binary content
> -------------------------------------------------------------------
>
> Key: OAK-2787
> URL: https://issues.apache.org/jira/browse/OAK-2787
> Project: Jackrabbit Oak
> Issue Type: Wish
> Components: lucene
> Reporter: Chetan Mehrotra
> Fix For: 1.8
>
>
> With Lucene based indexing the indexing process is single threaded. This
> hamper the indexing of binary content as on a multi processor system only
> single thread can be used to perform the indexing
> [~ianeboston] Suggested a possible approach [1] involving a 2 phase indexing
> # In first phase detect the nodes to be indexed and start the full text
> extraction of the binary content. Post extraction save the binary token
> stream back to the node as a hidden data. In this phase the node properties
> can still be indexed and a marker field would be added to indicate the
> fulltext index is still pending
> # Later in 2nd phase look for all such Lucene docs and then update them with
> the saved token stream
> This would allow the text extraction logic to be decouple from Lucene
> indexing logic
