The desired sampling level. Can be set to run faster at the cost of accuracy or for higher accuracy but a decrease in query execution speed.
|DEFAULT||Returns response with a sample size that balances speed and accuracy.|
|FASTER||Available only when using the V3 API. Returns a fast response with a smaller sample size.|
|HIGHER_PRECISION||Available only when using the V3 API. Returns a more accurate response using a large sample size, but this may result in the response being slower.|
|SMALL||Similar to FASTER, but for the V4 API.|
|LARGE||Similar to HIGHER_PRECISION, but for the V4 API.|
