Check target data rows are all unique

Source: R/check_target_tbl_rows_unique.R
check_target_tbl_rows_unique.Rd

Check that there are no duplicate rows in target data files being validated.

Usage

check_target_tbl_rows_unique(
  target_tbl,
  target_type = c("time-series", "oracle-output"),
  file_path,
  hub_path
)

Arguments

target_tbl

A tibble/data.frame of the contents of the target data file being validated.

target_type

Type of target data to retrieve matching files. One of "time-series" or "oracle-output". Defaults to "time-series".

file_path

A character string representing the path to the target data file relative to the target-data directory.

hub_path

Either a character string path to a local Modeling Hub directory or an object of class <SubTreeFileSystem> created using functions s3_bucket() or gs_bucket() by providing a string S3 or GCS bucket name or path to a Modeling Hub directory stored in the cloud. For more details consult the Using cloud storage (S3, GCS) in the arrow package. The hub must be fully configured with valid admin.json and tasks.json files within the hub-config directory.

Value

Depending on whether validation has succeeded, one of:

  • <message/check_success> condition class object.

  • <error/check_failure> condition class object.

Returned object also inherits from subclass <hub_check>.

Details

If datasets are versioned, multiple observations are allowed in time-series target data, so long as they have different as_of values. The as_of column is therefore included when determining duplicates. In oracle-output data, there should be only a single observation, regardless of the as_of value so the column it is not be included when determining duplicates.
