For speed, start at the DB and work back: Teradata FastLoad - Wikipedia, the free encyclopedia

FastLoad works with flat files and empty tables, perl can write flat files, and you can make an empty staging table. The big challenge is getting data inside the db; table to table is usually much faster and low overhead. For stremaing data, think mini-batches and be amazed how near real time it can be. You could even do simple inserts for lowest latency on a simple connection, buffering input with another thread, until a buffer high water line is passed, and then switch to mini-batch until a low water line is passed. Writing the next file while the current one is being FastLoad'd and unstaged means you can get a high peak capability with minimal latency (another thread). The higher the load, the bigger the batches and latency get, but economy of scale softens the curve. If the buffering format is FastLoad compatible, moving buffered to file is faster and easy.

NAME
mailping-latency - Munin plugin to graph latency of mail deliveries SYNOPSIS
/usr/share/mailping/munin-plugins/mailping-latency {[config] | ['']} DESCRIPTION
mailping-latency is a Munin plugin that monitors the time spent between email submit and it's delivery. Configuration output When passed config, it outputs Munin configuration information. If there are no circuits defined (no subdirectories in /etc/mailping), it specifies that Munin should draw no graph either. If configuration files /etc/mailping/circuit/warnlatency and /etc/mailping/circuit/faillatency exist, the values in them are passed on to Munin, for use in Nagios alert integration. Value output When passed an empty string '', mailping-latency outputs latency of last successful probe message, for each configured circuit. FILES
/etc/mailping/ List of circuits that exist; each subdirectory is a circuit. /etc/mailping/circuit/warnlatency If latency is greater than this many seconds, a Nagios warning is triggered by Munin (assuming it has been configured to do that). Default: no warnings. /etc/mailping/circuit/faillatency If latency is greater than this many seconds, a Nagios alert is triggered by Munin (assuming it has been configured to do that). Default: no alerts. /var/lib/mailping/state/circuit/latency Amount of latency in seconds of the last successful probe for circuit. ENVIRONMENT
MAILPING_CONFIGDIR Override the location of the configuration directory. Default: /etc/mailping MAILPING_STATEDIR Override the location of the state directory. Circuit states are stored in the state subdirectory of this directory, in subdirectories named after the circuit name. Default: /var/lib/mailping SEE ALSO
