area/retention policies
Customer operating "shared" clusters frequently run into issues where a user will attempt to write data in to the cluster and the time is skewed either deeply into the future or significantly into the past.
Clean-up of this "bad data" is then problematic, time consuming, etc.
Add
FutureWriteLimit
andPastWriteLimit
to retention policies. Points which are outside of now() + FutureWriteLimit or now() - PastWriteLimit will be rejected on write with a PartialWriteError.The default will be zero for both values, which behaves as the current product.
There will be corresponding work for Enterprise and InfluxQL.
