Why the “cell physical IO interconnect bytes” statistic is greater than the “cell physical IO interconnect bytes returned by smart scan” statistic.

By: Answerout


Here is the solution for Why the “cell physical IO interconnect bytes” statistic is greater than the “cell physical IO interconnect bytes returned by smart scan” statistic.. The solution is given after the options.

Why the “cell physical IO interconnect bytes” statistic is greater than the “cell physical IO interconnect bytes returned by smart scan” statistic.

There is a transaction, which committed after the query began, that has modified some of the table blocks, causing some “cell single block physical reads” to be requested by the database instance, resulting in additional I/O.

There are chained rows in the table, causing some “single block physical reads” to be requested by the database instance, resulting in additional I/O.

The table is a hash clustered table, causing “cell multiblock physical reads” to be requested by the database instance, resulting in additional I/O.

The table is list partitioned, causing “cell list of blocks physical reads” to be requested by the database instance, resulting in additional I/O.

There is a local index on a list partitioned table on the column used in the WHERE clause, causing “cell list of blocks physical reads” to be requested by the database instance, resulting in additional I/O.

Correct Answer

The table is a hash clustered table, causing “cell multiblock physical reads” to be requested by the database instance, resulting in additional I/O. The table is list partitioned, causing “cell list of blocks physical reads” to be requested by the database instance, resulting in additional I/O.

Explanation:

The table is a hash clustered table, causing “cell multiblock physical reads” to be requested by the database instance, resulting in additional I/O. The table is list partitioned, causing “cell list of blocks physical reads” to be requested by the database instance, resulting in additional I/O. is the answer for Why the “cell physical IO interconnect bytes” statistic is greater than the “cell physical IO interconnect bytes returned by smart scan” statistic.
