Elasticsearch configuration settings

The following properties are applicable to both embedded and client setup.

Property Description Default The name of the Elasticsearch cluster to connect to activiti-elastic-search-cluster The name of the specific node of this server. The client node will have this name plus the suffix -client. In the embedded setup there will also be a data node with a -data suffix. activiti The name of the index in which the data will be stored. Only change this if there is a name clash for some reason in your Elasticsearch installation activiti
elastic-search.tenant.index.prefix When running Alfresco Process Services with multi-tenancy, each tenant has its own index alias. Change this value to change the prefix applied to the alias. activiti_tenant
elastic-search.enable.http Enables the HTTP REST API of Elasticsearch. It is advised not to set this to true, unless traffic to it is strictly controlled by firewall rules. false


Enables (when elastic-search.enable.http is true) cross-origin resource sharing, that is, whether a browser on another origin can do requests to Elasticsearch.


Elasticsearch nodes (both client and data Elasticsearch nodes: therefore, this applies for both embedded and client setups) need to find each other to work in a clustered setup. This can be configured using multicast or unicast:

To change the type of discovery:

Property Description


elastic-search.discovery.type The way nodes find each other: multicast or unicast. multicast

When using multicast, the following properties can be set:



Default The multicast group address to use.
elastic-search.discovery.multicast.port The multicast port to use. 54328
elastic-search.discovery.multicast.ttl The time-to-live of the multicast message. 3
elastic-search.discovery.multicast.address The address to bind to.

All available network interfaces (

When using unicast, only one property needs to be set:




elastic-search.discovery.hosts The way nodes find each other: multicast or unicast. Either an array setting or a comma delimited setting. Each value is either in the form of host:port, or in the form of host[port1-port2]
