If not set, the value of `packetSize` defaults to 131072 (128KB) and `packetSizeLimit` defaults to `packetSize`. Values for `packetSize` may range from 65536 (64KB) to 1073741823 (1GB-1). Values for `packetSizeLimit` may range from `packetSize` to 1073741823 (1GB-1).

### Controlling the Data Format Version
By default, the node-hdb driver uses version 1 of the SAP HANA data format. Attempting to use a higher version than the server supports will result in an error. See the [documentation](tbd: add link) for more information on which data types are supported in which version.

For example, the following configuration will set the version to 7:
```js
var client = hdb.createClient({
host : 'hostname',
port : 30015,
dataFormatSupport : 7,
...
});
```
