# BufferingHints
<a name="API_BufferingHints"></a>

Describes hints for the buffering to perform before delivering data to the destination. These options are treated as hints, and therefore Firehose might choose to use different values when it is optimal. The `SizeInMBs` and `IntervalInSeconds` parameters are optional. However, if specify a value for one of them, you must also provide a value for the other.

 ** IntervalInSeconds **   <a name="Firehose-Type-BufferingHints-IntervalInSeconds"></a>
Buffer incoming data for the specified period of time, in seconds, before delivering it to the destination. The default value is 300. This parameter is optional but if you specify a value for it, you must also specify a value for `SizeInMBs`, and vice versa.  
Type: Integer  
Valid Range: Minimum value of 0. Maximum value of 900.  
Required: No

 ** SizeInMBs **   <a name="Firehose-Type-BufferingHints-SizeInMBs"></a>
Buffer incoming data to the specified size, in MiBs, before delivering it to the destination. The default value is 5. This parameter is optional but if you specify a value for it, you must also specify a value for `IntervalInSeconds`, and vice versa.  
We recommend setting this parameter to a value greater than the amount of data you typically ingest into the Firehose stream in 10 seconds. For example, if you typically ingest data at 1 MiB/sec, the value should be 10 MiB or higher.  
Type: Integer  
Valid Range: Minimum value of 1. Maximum value of 128.  
Required: No
