Hi,
I am not asking about the file formats. Rather, It is about SolrInputFormat
and SolrOutputFormat interfaces which deal with getsplit(), getRecordReader()
and getRecordWriter() methods. Are there any Implementations for these
interfaces?
Thanks,
Ranganath B. N.

Hi All,
Can you point me to some of the implementations of Solr Input and Output
format? I wanted to know them to understand the distributed implementation
approach.
Thanks,
