Choose a Data Warehouse Parser
CloudConnect is a legacy tool and will be discontinued. We recommend that to prepare your data you use the GoodData data pipeline as described in Data Preparation and Distribution. For data modeling, see Data Modeling in GoodData to learn how to work with Logical Data Modeler.
When choosing a Vertica parser for uploading data to Data Warehouse, consider the following recommendations:
Recommended for use: Native parser (no parser specified in COPY)
- Advantages: Fast (uses parallel parsing); can be used for updating ETL
- Disadvantages: Has a parsing limitation when an escape character cannot be the same as a quoting character (enclosed by), which is required by the RFC compliant CSV format
Only use when the native parser cannot be used: GdcCsvParser (for an example of how to use it, see Use RFC 4180 Compliant CSV Files for Upload)
- Advantages: Is able to override the parsing limitation of the native parser, that is, an escape character can be the same as a quoting character (enclosed by)
- Disadvantages: Significantly slower than the native parser (uses serial parsing); cannot be used for updating ETL
If you choose to use GdcCsvParser, review the options that you can use with it (see GdcCsvParser Options).
