Configuration Options
To configure Aerospike Graph Service (AGS), you can specify options with a properties file and/or with environment variables passed to the Docker image. If you use both, the options are combined when the Docker container starts.
Configuration file setup
To specify configuration options in a properties file, use a file named
aerospike-graph.properties. When starting the AGS Docker
image, bind your local properties file with the -v option.
For example, if your local properties file is located at
/Users/graph-user/conf/aerospike-graph.properties, start the Docker image
with the command:
docker run -p8182:8182 -v \
/Users/graph-user/conf/aerospike-graph.properties:/opt/aerospike-graph/aerospike-graph.properties \
aerospike/aerospike-graph-service
Specify configuration options with the format <OPTION>=<VALUE>. The following is
an example of a aerospike-graph.properties file:
aerospike.client.host=172.17.0.2
aerospike.client.port=3000
aerospike.client.namespace=test
aerospike.graph-service.heap.max=16g
Configuration options
Configuration options are organized into the following groups:
Options in the
aerospike.client.*group specify details of AGS's Aerospike client configuration and network setup.Options in the
aerospike.graph-service.*group specify details of your AGS's server setup.Options in the
aerospike.graph.*group specify details of your graph database setup.Options in the
aerospike.graphloader.*group configure the Aerospike Bulk Loader.
The following configuration options are available:
aerospike.client.* options
Option: aerospike.client.auth.mode
Default: INTERNAL
Allowable values: EXTERNAL, EXTERNAL_INSECURE, INTERNAL, PKI
EXTERNAL: Use external authentication (like LDAP) when username/password are defined.
EXTERNAL_INSECURE: Use external authentication (like LDAP) when username/password are defined.
INTERNAL: Use internal authentication when username/password are defined.
PKI: Authentication and authorization based on a certificate.
Option: aerospike.client.cluster.name
Default: none
Allowable values: String values.
Name of a running Aerospike Database server cluster. If set, this value
validates that the server cluster which AGS connect to matches the configuration.
Option: aerospike.client.host
Default: localhost:3000
Allowable values: Any string that follows <host>:<port> format.
Accessible address of one or more Aerospike seed nodes, specified as
<host>:<port> in a comma-separated list.
Option: aerospike.client.namespace
Default: test
Allowable values: String values. Must match an existing Aerospike namespace.
Namespace to use for storage of graph data.
This namespace must already exist on the Aerospike database cluster before starting AGS.
Option: aerospike.client.password
Default: none
Allowable values: String values. Must match Aerospike password for specified user.
Password to use when connecting to the Aerospike cluster if login security
is enabled.
Option: aerospike.client.services.alternate
Default: false
Allowable values: true, false
AGS uses services-alternate instead of services in its info request during cluster
tending. services-alternate returns server-configured external IP addresses that
AGS clients use to talk to nodes. services-alternate can be used in place of
providing a client ipMap.
Option: aerospike.client.socket.timeout
Default: 1200000 (20 minutes)
Allowable values: Integer values.

reocords to be read. The time allowed includes both scanning and
secondary index pagination queries.
Option: aerospike.client.timeout
Default: 2000
Allowable values: 1 - 100000
Timeout for all client operations except pagination reads (in milliseconds).
Option: aerospike.client.tls
Default: false
Allowable values: true, false
Enable TLS.
Option: aerospike.client.user
Default: none
Allowable values: String values. Must match a user configured for the Aerospike
database intance.
Username to use when connecting to the Aerospike cluster if login security
is enabled.
aerospike.graph-service.* options
Option: aerospike.graph-service.evaluationTimeout
Default: 30000
Allowable values: Integer values.
Time in milliseconds to wait for a request (script or bytecode) to complete execution.
Option: aerospike.graph-service.gremlinPool
Default: 0, indicating that the value is set to the number of available processors.
Allowable values: Integer values.
Size of the Gremlin thread pool. This pool handles Gremlin script execution and other
related long-running processing jobs.
Option: aerospike.graph-service.heap.max
Default: 80% of available system memory
Allowable values: Integer followed by unit (g for gigabytes or m for megabytes)
Maximum amount of memory to allocate to the graph service. Examples: 8192m, 4g
Option: aerospike.graph-service.heap.min
Default: none
Allowable values: Integer followed by unit (g for gigabytes or m for megabytes)
Minimum amount of memory to allocate to the graph service.
Option: aerospike.graph-service.idleConnectionTimeout
Default: 0, indicating that feature is disabled.
Allowable values: Integer values.
Time in milliseconds that the server allows a channel to receive no
requests from a client before it automatically closes. If enabled,
the value provided should exceed the amount of time given
to the configuration option aerospike.graph-service.keepAliveInterval.
This value is given in milliseconds, but it resolves to second precision.
Option: aerospike.graph-service.keepAliveInterval
Default: 0, indicating that feature is disabled.
Allowable values: Integer values.
Time in milliseconds that the server allows a channel to send no
responses to a client before it sends a "ping" to see if the channel is
still present. If it is present, the client should respond with a "pong"
which resets the aerospike.graph-service.idleConnectionTimeout and keeps
the channel open. If enabled, the value assigned to this option should be
smaller than the value provided to the option aerospike.graph-service.idleConnectionTimeout.
This value is given in milliseconds, but it resolves to second precision.
Option: aerospike.graph-service.port
Default: 8182
Allowable values: Integer values in the allowable port range.
