Q

John created a database and set the DATA_RETENTION_TIME_IN_DAYS as 30 days, but he did not set the DATA_RETENTION_TIME_IN DAYS in one of the table ‘T1’. after 5 days, he accidently dropped table ‘T1’. will he be able to recover the table T1?

100
Q

normally a warehouse begins to consume credits once all the servers are provisioned for the warehouse

TRUE or FALSE

TRUE

101
Q

what are the key considerations for using warehouse effectively and efficiently?

a) experiment with different types of queries and different warehouse sizes to determine the combinations that best meet your specific query needs and workloads
