--- layout: doc_page --- Realtime Node Configuration =========================== For general Real-time Node information, see [here](Realtime.html). For Real-time Ingestion, see [Realtime Ingestion](Realtime-ingestion.html). Quick Start ----------- Run: ``` io.druid.cli.Main server realtime ``` With the following JVM configuration: ``` -server -Xmx256m -Duser.timezone=UTC -Dfile.encoding=UTF-8 druid.host=localhost druid.service=realtime druid.port=8083 druid.extensions.coordinates=["io.druid.extensions:druid-kafka-seven:0.6.59"] druid.zk.service.host=localhost # The realtime config file. druid.realtime.specFile=/path/to/specFile # Choices: db (hand off segments), noop (do not hand off segments). druid.publish.type=db druid.db.connector.connectURI=jdbc\:mysql\://localhost\:3306/druid druid.db.connector.user=druid druid.db.connector.password=diurd druid.processing.buffer.sizeBytes=100000000 ``` 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/realtime druid.extensions.coordinates=["io.druid.extensions:druid-s3-extensions:0.6.59","io.druid.extensions:druid-kafka-seven:0.6.59"] druid.zk.service.host=#{ZK_IPs} druid.zk.paths.base=/druid/prod druid.s3.accessKey=#{ACCESS_KEY} druid.s3.secretKey=#{SECRET_KEY} druid.db.connector.connectURI=jdbc:mysql://#{MYSQL_URL}:3306/druid druid.db.connector.user=#{MYSQL_USER} druid.db.connector.password=#{MYSQL_PW} druid.db.connector.useValidationQuery=true druid.db.tables.base=prod druid.publish.type=db druid.processing.numThreads=3 druid.request.logging.type=file druid.request.logging.dir=request_logs/ druid.realtime.specFile=conf/schemas.json druid.segmentCache.locations=[{"path": "/mnt/persistent/zk_druid", "maxSize": 0}] druid.storage.type=s3 druid.storage.bucket=#{S3_STORAGE_BUCKET} druid.storage.baseKey=prod-realtime/v1 druid.monitoring.monitors=["com.metamx.metrics.SysMonitor", "io.druid.segment.realtime.RealtimeMetricsMonitor"] # 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 realtime module also uses several of the default modules in [Configuration](Configuration.html).
