ClickLag
Specify the minimum number of seconds (lag) between clicks, such as 0.2 seconds between each click, for the session user to be considered human. If time between clicks is less than the lag timeframe, indicating that the user is a bot, the function ignores the session. The minimum lag must be less than the timeout threshold. The data type of min_click_lag is DOUBLE PRECISION.
Default: The function ignores no session, regardless of click frequency.
EmitNull
Specify whether to output rows that have NULL values in their session id and rapid fire columns, even if their time_column has a NULL value.
Default: false.
