what is a feed handler?

[K4 Monk]

I have two questions in one, first, is a feed handler provided by say
Reuters or Bloomberg, or is it supplied by Kx? Secondly, I keep
hearing about kdb+tick in abstract terms. Is kdb+tick a database
system like Oracle/Sybase which is proprietary or is it something we
can write ourselves?

thanks!

Feed handlers are simply processes that

1) capture data according to a set of rules

2) translate(/enrich) that data from one format to another

3) cache some most recent values

They can be quite simple things to write, if you understand the formats, apis and data. Hence you may find several sources for feed handlers.

kdb+tick is a framework for a set of processes for real-time data capture, persistence and analysis. I think your employers have already licensed this package - if you need a contact within your organization, email me privately and I'll put you in touch.

thanks,

Charlie
