------------------------------------
Summary: Faster multi threaded indexing 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
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
