AWS Kinesis Analytics-数据聚合

Question

Ive been looking at AWS Kinesis analytics for some time now, and I struggle to make a following scenario work:

Say you have a Firehose that is connected to Kinesis Analytics as input stream. This firehose is meant to output data every 60s . I write data into this Firehose each 2s or so like: {"value":1} . Where the 1 is a random integer (can be 1, 5, 32 and so on).
How can I write my analytics to say find average value of all values reported in last 60s and pass it to a lambda?

I tried using various windows - however the Analytics seems to output the data every few seconds, instead of once 60s.
