database - Need of a redis server in a centralized setup -


i have gone through documentation on logstash server find out require redis server act broker. here link:

http://logstash.net/docs/1.1.12/tutorials/getting-started-centralized

but not clear me why use redis @ broker?

we rather directly ship logs elastic search logstash itself, save need of redis broker. why go shipper , indexer ?

need clear explanation.

thanks.

i believe can find answer here:

https://groups.google.com/forum/#!topic/logstash-users/vakcoazzi8k

redis acts temporary key value store raw shipper information parsed indexer. log info stored in elasticsearch, , not in redis.

apparently idea offload indexing server dedicated such tasks, indexing cpu intensive. redis being called broker seems appropriate, guess.
