Is DataImportHandler ThreadSafe???

[gurudev <su...@yahoo.com>]

Hi,
Just wanted to know, Is the DataImportHandler available in solr1.3
thread-safe?. I would like to use multiple instances of data import handler
running concurrently and posting my various set of data from DB to Index.

Can I do this by registering the DIH multiple times with various names in
solrconfig.xml and then invoking all concurrently to achieve maximum
throughput? Would i need to define different data-config.xml's &
dataimport.properties for each DIH?

If it would be possible to specify the query in data-config.xml to restrict
one DIH from overlapping the data-set fetched by another DIH through some
SQL clauses?
