Data Length Conditions
A Data Length condition matches a column based on the length, always measured in UTF-8 bytes, of its sampled values (a sampled subset; see Sampling) rather than their content, for example, flagging columns whose values are consistently longer than a typical free-text field.
Fields
Section titled “Fields”- Comparator — see Classifier Rules: Comparators for the shared numeric comparison options.
- Length — the numeric cutoff each sampled value’s length is compared against.
- Trim whitespace before evaluating — an optional toggle that strips leading and trailing whitespace before measuring length.
- Match Threshold — the share of non-null sampled values that must satisfy the comparison for the condition to pass. Defaults to 80%.
Example
Section titled “Example”This condition matches a column whose non-null sampled values are at least 100 UTF-8 bytes in length after trimming, requiring at least 80% of them to match:
{ "target": "DATA_LENGTH", "comparator": "greater_than_or_equal", "length": 100, "trim": true, "minimum_threshold": 80 }Behavior
Section titled “Behavior”-
Each non-null sampled value’s length (trimmed first, if that option is set) is compared against the cutoff. An all-null or empty column never passes.
-
A match on Data Length alone always produces a Low Match Confidence badge.
Availability
Section titled “Availability”Data Length conditions evaluate on every classification job, with no gating by data source or processing location. See Classification Processing Location for the full picture.
