zabbix_sender stores same measurement multiple times

[Frans Kunst]

Using zabbix_sender's -T-option (input file with timestamps) sending a line with same host, timestamp and key results in duplicate records.

Wouldn't it be better if the last value sent for a host/timestamp/key-combination replaces the previously stored value for this combination?

(tested on Zabbix 1.8.4 with item type 'numeric (float)')

I've started a thread with similar problem...
Any updates?
