apache lucene , katta, hadoop synchronization issue

[Ghulam Mustafa Malik <mu...@gmail.com>]

Dear All,

We are using these technologies,

Apache Lucene : --- for Indexing ..index are being generated by hibernate,
Hadoop:  --  using HDFS, for index storage and for distribution to Katta
nodes,
Katta:-- distributed nodes ... for searching

Things are partially working, but keeping in mind the search latency and
synchronization issues!!! we have not any mechanism to handle it!!! how can
we synchronize our Katta nodes indexes sync with our database updates and
deletes operations!!


Regards,
Ghulam Mustafa

Katta doesn't provide NRT or incremental indexing because it's a write
once architecture.  Though you can verify on the Katta mailing list.
