Few questions regarding the DataImportHandler: 1) My company is currently using Solr 1.2 and upgrading to 1.3 isn't in the immediate near term horizon, so I was wondering how difficult would it be to use the DIH and SolrJ from 1.3 to post documents to a Solr 1.2 server? We currently have a lot of custom loaders from MySQL that would be good to move away to the new DIH and SolrJ. I saw a discussion about someone wanting to use this externally from the solr server and I too would like this (if the loader crashes, I don't want the server going down with it). 2) How difficult is it to write data import extensions for other sources? Has anyone written an import extension from sources such as Memcache (for data persisted there)? I am also going to try and write an extension to import data from Hypertable (www.hypertable.org). 3) Is it worth possibly extending the cached SQL entity processor to persist to memcache instead of local cache for distributed search servers?
Thanks
