Description

The client should send a DELETE to the server to delete old data regularly.

Would really like this for 0.3.

Note that currently we wipe all data on version upgrades, and that's why this is not a P1.

Server history and client local history have different meaning.
Somewhere should be separete settings of a server trail properties. 
For public services it should be server-side hard limits.
For private servers limits can be client-depended.

There shouldn't be a situation, where purging of client history cleans all server history. Only "clear server data" or special "server housekeeping" should clean server history.

In real life often uses limits "by size in KB", "by record count", "by age", in many combinations, with upper limits, and guaranteed spaces. 
If a "reference" server will newer propose this functionality, it should not disable this possibilities at all.

One of possible variants to make housekeeping on server side - replace old record with new if record count limit touched... For example, remove 10% of old records, when user tries to add 100%th record.

This bug is to implement the bare minimum required--simply to delete old records based on some hardcoded criteria.  But, it would be nice if it was configurable, sure.

I agree that some of this work could/should be done server-side.  We should explore that possibility in future iterations of the client/server.
