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:0.6.98"]
|
|
|
|
|
|
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
|
|
```

|
|
```
|
|
-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
