Example Graph Configuration
This page illustrates a number of common graph configurations. Please refer to ??? and the pages of the respective storage backend index backend for more information.
Also, note that the JanusGraph distribution includes local configuration
files in the conf/
directory.
BerkeleyDB
1 2 3 4 5 6 7 | storage.backend=berkeleyje storage.directory=/tmp/graph index.search.backend=elasticsearch index.search.directory=/tmp/searchindex index.search.elasticsearch.client-only=false index.search.elasticsearch.local-mode=true |
This configuration file configures JanusGraph to use BerkeleyDB
as an embedded storage backend, meaning, JanusGraph will start
BerkeleyDB internally. The primary data will be stored in the directory
/tmp/graph
.
In addition, this configures an embedded Elasticsearch
index backend with the name search
. JanusGraph will start
Elasticsearch internally and it will not be externally accessible since
local-mode
is enabled. Elasticsearch stores all data for the search
index in /tmp/searchindex
. Configuring an index backend is optional.
Cassandra
Cassandra Remote
1 2 3 4 5 6 | storage.backend=cql storage.hostname=100.100.100.1, 100.100.100.2 index.search.backend=elasticsearch index.search.hostname=100.100.101.1, 100.100.101.2 index.search.elasticsearch.client-only=true |
This configuration file configures JanusGraph to use
Cassandra as a remote storage backend. It assumes that a
Cassandra cluster is running and accessible at the given IP addresses.
If Cassandra is running locally, use the IP address 127.0.0.1
.
In addition, this configures a remote Elasticsearch
index backend with the name search
. It assumes that an Elasticsearch
cluster is running and accessible at the given IP addresses. Enabling
client-only
ensures that the local instance does not join the existing
Elasticsearch cluster as another node but only connects to it.
Configuring an index backend is optional.
Embedded Cassandra
1 2 3 4 5 6 7 | storage.backend=embeddedcassandra storage.conf-file=config/cassandra.yaml index.search.backend=elasticsearch index.search.directory=/tmp/searchindex index.search.elasticsearch.client-only=false index.search.elasticsearch.local-mode=true |
This configuration file configures JanusGraph to start Cassandra internally embedded in JanusGraph and specifies the yaml configuration file for Cassandra. Cassandra is still accessible externally and can connect to other available Cassandra nodes to form a cluster as configured in the yaml file.
The optional index backend configuration is identical to embedded index configuration described above.
HBase
1 2 3 4 5 6 7 | storage.backend=hbase storage.hostname=127.0.0.1 storage.port=2181 index.search.backend=elasticsearch index.search.hostname=127.0.0.1 index.search.elasticsearch.client-only=true |
This configuration file configures JanusGraph to use HBase as
a remote storage backend. It assumes that an HBase cluster is running
and accessible at the given IP addresses through the configured port. If
HBase is running locally, use the IP address 127.0.0.1
.
The optional index backend configuration is identical to remote index configuration described above.
