The absolute easiest approach would be to support a new init value for codecFactory, which SchemaCodecFactory would use to select a different base codec class to use (versus always using Lucene<version>Codec). That would switch everything to a different codec. Or you could extend the SchemaCodecFactory to support additional per-field settings for stored fields format, etc beyond what's currently available. For my quick & dirty hack I've specified a different codecFactory in solrconfig.xml, and have my own factory that hard-codes the SimpleTextCodec. This works - all files are in the SimpleTextXXX format, other than the segments.gen and segments_XX files; what, those aren't pluggable?!?! :) -- Ken -------------------------- Ken Krugler +1 530-210-6378 http://www.scaleunlimited.com custom big data solutions & training Hadoop, Cascading, Cassandra & Solr
