I have been looking at search solutions like Sphinx, Solr and Elasticsearch but they are all way too complex for what I need.
I'm basically looking for a server software, best distributed, that allows me to just throw in chunks of text associated with a single small identifier each. Then find keywords quickly and return the identifiers given for the chunks that yielded a match with one or more of the keywords.
Does something like this exist?
Imagine a load-balancer facing the internet, dispatching requests to several worker-servers in a local network.
Is there a way for the worker-servers to respond directly on the original socket / connection / IP or do they have to respond to the load-balancer for it to forward the response (making it the SPOF)?
Let's say I have a fully working, load-balanced application server environment.
All servers have to fail-over gracefully. It's relatively easy to do with the application servers, but how can I achieve fail-over with the front load-balancer?
Can I have multiple load-balancers listening on the same IP and port? Do I have to run a new one as soon as I detect the old one died?
