You can _batch_ import your data using full import command by
providing additional request parameter ( see
http://wiki.apache.org/solr/DataImportHandler#Accessing_request_parameters
), i.e.
query="SELECT * FROM my_table ORDER BY id LIMIT 1000000 OFFSET
${dataimporter.request.offset}"
and then calling full-import command several times:
1) /dataimport?clean=true&offset=0
2) /dataimport?clean=false&offset=1000000
3) /dataimport?clean=false&offset=2000000
etc
// Please use solr-user@lucene.apache.org mailing list for such
questions. _dev_ is not appropriate place for this.
