DPE Configuration

In on-premise deployments, the following properties configure Data Processing Engine (DPE) and are provided either in the Configuration Service User Guide or in the dpe/etc/application.properties file.

In addition, the following properties can be specified for DPE as well:

Basic settings

Property Data type Description

ataccama.one.dpe.service.debug

Boolean

Enables debug logging mode. If set to true, job logs are shown in the server logs and temporary files are not cleaned immediately from the job workspace. The scheduler removes temporary job files later depending on the settings.

Default value: false.

ataccama.one.dpe.service.hostname

String

Used to send information to Data Processing Manager (DPM) about the location of DPE. If DPM cannot reach DPE by the machine hostname, this property overrides that hostname.

If not set, the hostname is determined by trying to resolve the DNS records for the localhost address.

Default value: localhost.

ataccama.one.dpe.service.port

Number

Used to send information to DPM about the location of DPE. If DPM cannot reach DPE by the gRPC port, this property overrides that port.

server.port

Number

The HTTP server port for DPE.

Default value: 8034.

ataccama.one.dpe.environment

A comma-separated list of environments in which this instance of DPE can be used. In the current release, this only affects user restrictions when accessing the file system data sources.

ataccama.one.dpe.name

String

A meaningful name for DPE that is used in DPM Admin Console. This is especially useful in firewall-friendly mode as it makes it easier to identify DPE instances. We recommend using alphanumeric characters without spaces.

If not set, the default value matches the hostname or the URL and the port of the DPE server. In firewall-friendly mode, the default value is 0.0.0.0 unless modified.

Communication mode between DPE and DPM

Starting from version 13.3.1, it is possible to enable communication over bidirectional gRPC stream between DPE and DPM. When this firewall-friendly mode is configured, the follow-up communication from DPM to DPE, such as browsing queries or submitting jobs, does not require opening DPE’s inbound ports to the outside world.

In cases when firewall-friendly mode cannot be configured, the TLS security can be set for all DPE by setting the DPM property ataccama.one.dpm.registry.enforce-tls or by enabling TLS security on selected DPE instances. We recommend checking the desired security level if any of your DPE instances communicate with DPM via internet.

Property Data type Description

ataccama.one.dpe.service.dpm.connection.mode

Defines how DPE connects to DPM.

The following options are available:

  • NORMAL_REGISTRATION: The default option. In this case, DPM continues attempting to create connections to DPE.

  • NO_DPM_REGISTRATION: Used for testing purposes. DPE does not attempt to register with DPM.

In cases when connection modes FIREWALL_FRIENDLY_REGISTRATION or NO_DPM_REGISTRATION are used, the following properties are ignored as they are transmitted to DPM only in order to establish a connection to DPE:

  • ataccama.one.dpe.service.hostname

  • ataccama.one.dpe.service.port

Default value: NORMAL_REGISTRATION.

ataccama.one.dpe.service.dpm.connection.firewall-friendly.max-server-termination-waiting

There are two types of persistent storage: the default embedded database and a custom data source. Using a custom data source instead of the embedded one is optional and requires further configuration. The driver required for the custom data source must be manually added to the lib folder with other database drivers.

Property Data type Description

If not specified, the system environment variable tmp is used. If the system environment variable is not set up, the temporary job folder is created in the root directory of the machine.

After each job finishes, the corresponding work files are automatically deleted from this directory.

You can change the default location of this directory by editing the custom starting script to which this property plugin.executor-launch-model.ataccama.one.launch-type-properties.LOCAL.exec is pointing to. For example: /opt/ataccama/bin/local/exec_local.sh.

The plugin.executor-launch-model.ataccama.one.launch-type-properties.LOCAL.exec property needs to be configured for this property to work.

plugin.executor-launch-model.ataccama.one.launch-type-properties.LOCAL.exec

String

References the script for customizing how local jobs are launched. For example, you can change which shell script is used to start the job. The script is located in the bin/local folder in the root directory of the module.

The default value for Linux is local/exec_local.sh.

You can use JAVA_OPTS to pass additional properties to the runtime.

Some useful examples include:

  • plugin.executor-launch-model.ataccama.one.launch-type-properties.LOCAL.env.JAVA_OPTS=-XX:MaxRAMPercentage=60: Sets the maximum size of the Java heap as a percentage of the total memory available to the JVM.

  • plugin.executor-launch-model.ataccama.one.launch-type-properties.LOCAL.env.JAVA_OPTS=-Ddqd.io.storage.compress=compress: If set to compress, the processed records kept in the file storage should be compressed.

    The default value is false. Used mainly for hybrid deployment.

plugin.executor-launch-model.ataccama.one.launch-type-properties.LOCAL.cp.!exclude
