Simple Cluster Configuration
|
|
===============================
|
|
|
|
This simple Druid cluster configuration can be used for initially experimenting with Druid on your local machine. For a more realistic production Druid cluster, see [Production Cluster Configuration](../configuration/production-cluster.html).
|
|
|
|
### Common Configuration (common.runtime.properties)
|
|
|
|
```
|
|
# Extensions
|
|
-Ddruid.extensions.coordinates=["io.druid.extensions:druid-kafka-eight"]
|
|
|
|
# Zookeeper (defaults to localhost)
|
|
|
|
# Metadata Storage (defaults to derby with no username and password)
|
|
```
|
|
|
|
### Overlord Node (Indexing Service)
|
|
|
|
Run:
|
|
|
|
```
|
|
io.druid.cli.Main server overlord
|
|
```
|
|
|
|
Configuration:
|
|
|
|
```
|
|
-server
|
|
-Xmx256m
|
|
-Duser.timezone=UTC
|
|
-Dfile.encoding=UTF-8
|
|
-Djava.util.logging.manager=org.apache.logging.log4j.jul.LogManager
|
|
|
|
-Ddruid.indexer.queue.startDelay=PT0M
|
|
-Ddruid.indexer.runner.javaOpts=-server -Xmx1g
|
|
-Ddruid.indexer.fork.property.druid.processing.numThreads=1
|
|
-Ddruid.indexer.fork.property.druid.computation.buffer.size=100000000
|
|
```
|
|
|
|
This runs the indexing service in local mode, and can support real-time ingestion tasks (with one processing thread for queries).
|
|
|
|
### Coordinator Node
|
|
|
|
Run:
|
|
|
|
```
|
|
io.druid.cli.Main server coordinator
|
|
```
|
|
|
|
Configuration:
|
|
|
|
```
|
|
-server
|
|
-Xmx256m
|
|
-Duser.timezone=UTC
|
|
-Dfile.encoding=UTF-8
|
|
-Djava.util.logging.manager=org.apache.logging.log4j.jul.LogManager
|
|
|
|
druid.coordinator.startDelay=PT70s
|
|
```
|
|
|
|
This simple coordinator assumes local deep storage.
|
|
|
|
### Historical Node
|
|
|
|
Run:
|
|
|
|
```
|
|
io.druid.cli.Main server historical
|
|
```
|
|
|
|
Configuration:
|
|
|
|
```
|
|
-server
|
|
-Xmx256m
|
|
-Duser.timezone=UTC
|
|
-Dfile.encoding=UTF-8
|
|
-Djava.util.logging.manager=org.apache.logging.log4j.jul.LogManager
|
|
|
|
druid.server.maxSize=10000000000
|
|
|
|
druid.processing.buffer.sizeBytes=100000000
|
|
druid.processing.numThreads=1
|
|
|
|
druid.segmentCache.locations=[{"path": "/tmp/druid/indexCache", "maxSize"\: 10000000000}]
|
|
```
|
|
|
|
This historical node will be able to load 100 MB of data and be able to process 1 segment at a time. Deep storage is assumed to be local storage here.
|
|
|
|
### Broker Node
|
|
|
|
Run:
|
|
|
|
```
|
|
io.druid.cli.Main server broker
|
|
```
|
|
|
|
Configuration:
|
|
|
|
```
|
|
-server
|
|
-Xmx256m
|
|
-Duser.timezone=UTC
|
|
-Dfile.encoding=UTF-8
|
|
-Djava.util.logging.manager=org.apache.logging.log4j.jul.LogManager
|
|
|
|
druid.processing.buffer.sizeBytes=100000000
|
|
druid.processing.numThreads=1
|
|
```
|
|
|
|
This simple broker will run groupBys in a single thread.
