Array Size

Attribute

ArraySize (AS)

Purpose

The number of bytes the driver can fetch in a single network round trip. Larger values increase throughput by reducing the number of times the driver fetches data across the network. Smaller values increase response time, as there is less of a delay waiting for the server to transmit data.

Valid Values

An integer from 1 to 4,294,967,296 (4 GB)
The value 1 does not define the number of bytes but, instead, causes the driver to allocate space for exactly one row of data.

Notes

*This connection option can affect performance.

Default

60000
