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, ... ) ). For more information about HyperLogLog, see Estimating the Number of Distinct Values.expr1 The column or expression to partition the window by. For example, suppose that within each state or province, you want to rank farmers in order by the amount of corn they produced. In this case, you partition by state. If you want only a single group (e.g. you want to rank all farmers in the U.S. regardless of which state they live in ...

How Query Load is Calculated. Query load is calculated by dividing the execution time (in seconds) of all queries in an interval by the total time (in seconds) for the interval. The chart shows that, during the five-minute interval, the load from running queries was .92 and queued queries (due to warehouse overload) was .08.The Snowflake string parser, which parses literal strings, also treats backslash as an escape character. For example, a backslash is used as part of the sequence of characters that specifies a tab character. Thus to create a string that contains a single backslash, you must specify two backslashes.

APPROX_COUNT_DISTINCT. 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, ... ) ). For more information about HyperLogLog, see Estimating the Number of Distinct Values. In my opinion you can achieve this with two ways: Materializing the row count from information_schema.tables once a day into a new table (i.e. not materializing all the data from all your tables but just materializing the results of the view or even less just materializing the select sum(ROW_COUNT) from information_schema.tables;); Using time travel and run select count(*) from myTable at ...Already a Snowflake expert?
