Estimating a cost of performing database operations using vectorized instructions

A method comprising:

• determining one or more criteria;
• based on the one or more criteria, determining whether to perform an operation using a first approach that involves executing one or more vectorized instructions or using a second approach that does not involve executing any vectorized instruction;
• wherein the method is performed by one or more computing devices.

One or more storage media storing instructions which, when executed by one or more processors, further cause:

• determining a first cost of performing an operation using a first approach that involves executing one or more vectorized instructions;
• determining a second cost of performing the operation using a second approach that does not involve executing any vectorized instruction;
• based on the first cost and the second cost, determining whether to the perform the operation using the first approach or the second approach.

One or more storage media storing instructions which, when executed by one or more processors, cause:

• determining one or more criteria;
• based on the one or more criteria, determining whether to perform an operation using a first approach that involves executing one or more vectorized instructions or using a second approach that does not involve executing any vectorized instruction.
