It is possible to load Hadoop SequenceFile to Vertica?


  • I'm not aware of a direct loader for that format. (If someone else is, they could chime in.) If you have a command-line program that converts from SequenceFile to some delimited format (or any other format that we do support), you could plug it into Vertica using the ExternalFilter function in the open-source shell_load_package: There is also a parser for the Avro format in that github repository. That parser could, with some programming work, be modified to load SequenceFiles instead. Such a parser would certainly be a welcome contribution to the community.
