Companion object ExternalOffsetVerticaFileBatcher
class ExternalOffsetVerticaFileBatcher[R] extends RecordBatcher[ExternalOffsetVerticaFileRecordBatch] with Logging
A file based Vertica record batcher that generates a new file ID before starting a new batch from a given ID sequence, formats records using a given formatter and writes them to files.
A SEQUENCE is required for generating the _file_id foreign key values, create it as follows:
CREATE SEQUENCE file_id_sequence;
- R
