thanks for a quick response @venkatasri Actually that is our first schedule setup which is every 5mins it's just so happen that the client want a data updated of what will be the possible minimum time. So we change to 1min cron schedule and the SQL set as batch and get only past 1min of the data using updated time column. For us to resolve the missing data our work around is to get 90secs past data instead of 1min in SQL and the cron still 1min. But not sure though if this work this out. Any idea?/suggestion?
