- snowflake.snowpark.functions.approx_count_distinct(e: ColumnOrName) Column [source] (https://github.com/snowflakedb/snowpark-python/blob/release-v1.3.0/src/snowflake/snowpark/functions.py#L510-L514)¶
Uses HyperLogLog to return an approximation of the distinct cardinality of the input (i.e. HLL(col1, col2, … ) returns an approximation of COUNT(DISTINCT col1, col2, … )).
