--- layout: doc_page --- Historical Node Configuration ============================= For general Historical Node information, see [here](Historical.html). Quick Start ----------- Run: ``` io.druid.cli.Main server historical ``` With the following JVM configuration: ``` -server -Xmx256m -Duser.timezone=UTC -Dfile.encoding=UTF-8 druid.host=localhost druid.service=historical druid.port=8081 druid.zk.service.host=localhost druid.server.maxSize=10000000000 # Change these to make Druid faster druid.processing.buffer.sizeBytes=100000000 druid.processing.numThreads=1 druid.segmentCache.locations=[{"path": "/tmp/druid/indexCache", "maxSize"\: 10000000000}] ``` Note: This will spin up a Historical node with the local filesystem as deep storage. Production Configs ------------------ These production configs are using S3 as a deep store. JVM settings: ``` -server -Xmx#{HEAP_MAX}g -Xms#{HEAP_MIN}g -XX:NewSize=#{NEW_SIZE}g -XX:MaxNewSize=#{MAX_NEW_SIZE}g -XX:+UseConcMarkSweepGC -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -Duser.timezone=UTC -Dfile.encoding=UTF-8 -Djava.io.tmpdir=/mnt/tmp -Dcom.sun.management.jmxremote.port=17071 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false ``` Runtime.properties: ``` druid.host=#{IP_ADDR}:8080 druid.port=8080 druid.service=druid/prod/historical/_default druid.extensions.coordinates=["io.druid.extensions:druid-s3-extensions:#{DRUID_VERSION}"] druid.zk.service.host=#{ZK_IPs} druid.zk.paths.base=/druid/prod druid.s3.accessKey=#{ACCESS_KEY} druid.s3.secretKey=#{SECRET_KEY} druid.server.type=historical druid.server.maxSize=#{SERVER_MAXSIZE} druid.server.http.numThreads=50 druid.processing.buffer.sizeBytes=#{BUFFER_SIZE}} druid.processing.numThreads=#{NUM_THREADS}} druid.segmentCache.locations=[{"path": "/mnt/persistent/zk_druid", "maxSize": #{SERVER_MAXSIZE}}] druid.request.logging.type=file druid.request.logging.dir=request_logs/ druid.monitoring.monitors=["io.druid.server.metrics.ServerMonitor", "com.metamx.metrics.SysMonitor","com.metamx.metrics.JvmMonitor"] # Emit metrics over http druid.emitter=http druid.emitter.http.recipientBaseUrl=#{EMITTER_URL} # If you choose to compress ZK announcements, you must do so for every node type druid.announcer.type=batch druid.curator.compress=true ``` The historical module uses several of the default modules in [Configuration](Configuration.html) and has no uniques configs of its own.
