Load Data from KiFS

Copy and paste tutorial for loading data from Kinetica's File System (KiFS)

Unlike other data sources, you do not need to first create a credential and a data source object in Kinetica before ingesting data from KiFS.

Ingest Data

To initiate the ingest of data into a Kinetica table, use the LOAD INTO command for a one-time batch load. To reference files in KiFS, you can use a URL that looks like this:

kifs://<folder_name>/<filename>.<extension>
KiFS LOAD INTO Example

  LOAD INTO example.orders
  FROM FILE PATHS 'kifs://data/orders.csv'
  WITH OPTIONS (PRIMARY KEY = ('id'))

Considerations

The following are some common options used when loading. For the full list of options, see LOAD INTO. For copy/paste examples of many of the options, see Loading Data.


Error Handling

Kinetica has several different error handling modes for dealing with erroneous data. To halt ingestion after a bad record is found, use the ABORT mode. To skip erroneous records and continue the ingest, use the SKIP mode. If you wish to ingest erroneous records to the best of Kinetica's ability and continue the ingest, use the PERMISSIVE mode.

To inspect erroneous records, you may use the BAD RECORD TABLE NAME option. All bad records encountered will be stored there for review. The bad records table is limited to 10,000 records by default and may be overridden using the BAD RECORD TABLE LIMIT option.

    ON ERROR = SKIP
)

Load Specific Columns

In same cases, you may only want to store certain columns from your source data. Use the FIELDS MAPPED BY NAME(...) option, which allows you to specify the desired fields to store in Kinetica.

WITH OPTIONS (
  FIELDS MAPPED BY NAME(ID, Name, Product_ID, Quantity)
)

DateTime Formatting

Use the COLUMN FORMATS option to format date and time fields into Kinetica Date, Time, and DateTime columns. Time formats are specified using a JSON formatted string. Non-placeholder characters must be wrapped in quotes, which must also be escaped (e.g. '{"dt": {"date": "\"(\"YYYY\")\" Mon, DD"}}'). Alternatively, you can use the ? character as a wildcard character. Note that Kinetica does not handle or store timezones and they will be discarded. See the full list of of supported date and time format codes.
