public final class GenerateSolrSequenceKeyBuilder extends Object implements CommandBuilder
baseIdField
record field, followed by a running count of the record number within
the current session. The count is reset to zero whenever a "startSession" notification is
received.
For example, assume a CSV file containing multiple records but no unique ids, and the
baseIdField
field is the filesystem path of the file. Now this command can be used
to assign the following record values to Solr's unique key field:
$path#0, $path#1, ... $path#N
.
The name of the unique key field is fetched from Solr's schema.xml file, as directed by the
solrLocator
configuration parameter.
