> h3. Motivation
> Ignite logs are both excessive and in some places not indicative. Among other components raft provides redundant amount of logs. Single node cluster with 1_000 partitions will log (in attachement)
>  * Node {} init ballot box's lastCommittedIndex={}.
>  * Node {} init, term={}, lastLogId={}, conf={}, oldConf={}.
>  * Starts FSMCaller successfully [nodeId={}].
>  * Shutting down FSMCaller...
> 2054 times each
>  * Save raft meta, path={}, term={}, votedFor={}, cost time={} ms
> 4108 times.
> etc.
> Or 1_000 partitions will log "Unsuccessful election round number" > 327272 times if majority is lost for one hour.
> h3. Implementation notes
> After some discussions following is suggests:
>  # Change log level from "info" to "debug" for following messages:
>  ## {{{}[LOG.info|http://log.info/]{}}}{{{}("Node {} init ballot box's lastCommittedIndex={}.", getNodeId(), lastCommittedIndex);{}}}{{{}{}}}{{{}{}}}
>  ## {{{}[LOG.info|http://log.info/]{}}}{{{}("Starts FSMCaller successfully [nodeId={}].", nodeId);{}}}
>  ## {{{}[LOG.info|http://log.info/]{}}}{{{}("Shutting down FSMCaller...");{}}}
>  ## {{{}[LOG.info|http://log.info/]{}}}{{{}("Save raft meta, path={}, term={}, votedFor={}, cost time={} ms", this.path, this.term,this.votedFor, cost); if cost is small enough.{}}}
>  ## {{{}[LOG.info|http://log.info/]{}}}{{{}("Node {} is a learner, election timer is not started.", this.nodeId);{}}}
>  ## {{{}[LOG.info|http://log.info/]{}}}{{{}("Node {} received PreVoteRequest from {}, term={}, currTerm={}, granted={}, requestLastLogId={}, lastLogId={}.", getNodeId(), request.serverId(), request.term(), this.currTerm, granted, requestLastLogId, lastLogId);{}}}
>  ## {{{}[LOG.info|http://log.info/]{}}}{{{}("Node {} term {} start preVote.", getNodeId(), this.currTerm);{}}}
>  # Add lastCommittedIndex to
>  ## {{{}[LOG.info|http://log.info/]{}}}{{{}("Node {} init, term={}, lastLogId={}, conf={}, oldConf={}." {}}}
>  ## {{{}[LOG.info|http://log.info/]{}}}{{{}("Init node {} with empty conf.", this.serverId);{}}}
>  # For {{{}[LOG.info|http://log.info/]{}}}{{{}("Unsuccessful election round number {}, group '{}'", electionRound, groupId);{}}}
>  ## {{{}{}}}{{{}Print each for first 10.{}}}
>  ## Print every tents for 11-100.
>  ## Print every hundredth for the rest.
