truncateSchemaIfNecessary(schema: StructType, truncationThreshold: Long): (StructType, Map[String, String])
If the schema contains non-latin encoding characters, the schema can become garbled.
If the schema contains non-latin encoding characters, the schema can become garbled. We need to truncate the schema in that case. Also, if any of the fields is longer than
truncationThreshold, then the schema will be truncated to an empty schema to avoid corruption.- returns
a tuple of the truncated schema and a map of error messages if any. The error message is only set if the schema is truncated. Truncation can happen if the schema is too long or if it contains non-latin characters.
