Re: managing a limited-length list as a value

Maybe you can try this: use MAX-time as your column name, then get the first 
limit columns.

主题: managing a limited-length list as a value

The following is derived from the redis list operations.

The data model is that a key maps to an list of items. The operation
is to push a new item into the front, and discard any items from the
end above a threshold number of items.

of course, this can be done by reading a value, fiddling with it, and
writing it back. I write this email to wonder if there's any native
trickery to avoid having to read the value, but rather permitting some
sort of 'push' operation.
