Event Taxonomy Limitations

Category, Action, Label, Value

• Data Type: If the data type does not match the designated format, the event itself is not stored.
• Max Length: Anything that exceeds the designated maximum length is cut short to fit the maximum length.

Semantic Event Properties (Semantic Attributes)

• Data Type: If a "semantic attribute" (e.g. transactionID, totalValue) does not match the designated format, the event itself is not stored. However, if individual data fields of "Semantic Event Properties" (e.g. products.productID, products.name) do not match the designated type, the event is stored excluding the problematic field.
• Max Length: There are no length limitations for "semantic attributes". However, the value of "semantic attributes" are cut short if the length exceeds its limitations.

Custom Event Properties (Custom Attributes)

• Data Type: If the data type does not match the designated format, the event itself is not stored.
• Max Length: If the length exceeds the designated maximum length, the value is stored as ERROR_MAX_LENGTH_EXCEEDED.
