RUNTIME_FILTER_WAIT_TIME_MS Query Option (Impala 2.5 or higher only)
RUNTIME_FILTER_WAIT_TIME_MS query option
adjusts the settings for the runtime filtering feature.
It specifies a time in milliseconds that each scan node waits for
runtime filters to be produced by other plan fragments.
Default: 0 (meaning use the value from the corresponding impalad startup option)
Added in: Impala 2.5.0
Because the runtime filtering feature applies mainly to resource-intensive and long-running queries, only adjust this query option when tuning long-running queries involving some combination of large partitioned tables and joins involving large tables.
