[influxdb] Shard group duration recommendations

[t***@gmail.com]

Hello,

The Shard Group Duration Recommendations from https://docs.influxdata.com/influxdb/v1.2/concepts/schema_and_data_layout/#shard-group-duration-management give the following guidelines:

We recommend configuring the shard group duration such that:
* it is two times your longest typical query’s time range
* each shard group has at least 100,000 points per shard group
* each shard group has at least 1,000 points per series

Our typical queries would be for longer than a day (several dashboards are set to 90 days). I can easily meet points 2 and 3 with a day of data, but how important is point 1? If I set the shard group duration to 1d but we typically run queries with a much longer duration will we run into trouble?

Thanks,

Bill
