Available Events

This section lists events that are available in Apache Ignite 3.

Connection Events

These events are fired every time a client connects to the cluster, or disconnects from it.

Event Type	Description
CLIENT_CONNECTION_ESTABLISHED	Connection with the client established. Connection info contains information about the client.
CLIENT_CONNECTION_CLOSED	Connection with the client closed. Connection info contains information about the client.

Description

CLIENT_CONNECTION_ESTABLISHED

Connection with the client established. Connection info contains information about the client.

Authentication Events

These events are fired when the user performs an action that requires authentication.

Event Type	Description
USER_AUTHENTICATION_SUCCESS	User was authenticated on the cluster.
USER_AUTHENTICATION_FAILURE	User failed to authenticate on the cluster. Get the username from the event’s `identity` field.

USER_AUTHENTICATION_SUCCESS

User was authenticated on the cluster.

USER_AUTHENTICATION_FAILURE

Authorization Events

These events are fired when the user performs an action that requires authentication. Each event body has a list of privileges, where every privelege is an object with the action and selector. For more details see User Permissions and Roles section.

Event Type	Description
USER_AUTHORIZATION_SUCCESS	An action was authorized for the user on a specific object.
USER_AUTHORIZATION_FAILURE	An action was denied to the user on a specific object.

Query Events

These events are fired when the user performs a query.

Event Type	Description
QUERY_STARTED	A new query was started.
QUERY_FINISHED	Query execution is finished.

Event Type

Description

QUERY_STARTED

A new query was started.

Each query event has the following fields:

Field Name Description

Field Name	Description
initiator	Name of a node that initiated the query.
id	Query ID.
schema	Name of the schema that was used to resolve non-qualified object names.
sql	An original query string.
parentId	ID of the parent query, if any.
statementNumber	A 0-based index of query within the script, if applicable. Returns -1 otherwise.
txId	ID of the transaction, if known.
startTime	Time at which query appears on server. Applicable only to `QUERY_FINISHED` events.
type	Optional Type of the query, if known.
error	Optional An error, if one occurred during execution and caused the query to terminate.

An original query string.

parentId

ID of the parent query, if any.

statementNumber

A 0-based index of query within the script, if applicable. Returns -1 otherwise.

Compute Job Events

These events describe the possible states of a compute job.

Event Type	Description
COMPUTE_JOB_QUEUED,	Triggered when a compute job is added to the execution queue.
COMPUTE_JOB_EXECUTING,	Triggered when a compute job starts execution.
COMPUTE_JOB_FAILED,	Triggered when a compute job fails and throws an exception during execution.
COMPUTE_JOB_COMPLETED,	Triggered when a compute job is finished successfully.
COMPUTE_JOB_CANCELING,	Triggered when a compute job cancellation is requested.
COMPUTE_JOB_CANCELED,	Triggered when a compute job has been canceled.

Event Type

Description

COMPUTE_JOB_QUEUED,

Triggered when a compute job is added to the execution queue.

COMPUTE_JOB_EXECUTING,

Triggered when a compute job starts execution.

COMPUTE_JOB_FAILED,

Triggered when a compute job fails and throws an exception during execution.

COMPUTE_JOB_COMPLETED,

Compute Job Event Structure

Each compute job event has the following fields:

Field Name Description

Field Name	Description
type	Type of the compute job. Could be `SINGLE`, `BROADCAST`, `MAP_REDUCE` or `DATA_RECEIVER`. Single job is the most common type, assigned to jobs that are executed on a single node. Broadcast jobs are executed on many nodes simultaneously. Map reduce jobs are the jobs that are submitted from the map reduce task. Data receiver is an internal compute job that is used when data streamer API is used.
className	Class name of a job.
jobId	Compute job ID.
targetNode	Name of the node where a job is executed.
initiatorNode	Name of the node where a submit request is processed.
taskId	Optional Сommon ID for all broadcast compute jobs submitted from a single invocation.
tableName	Optional Table name for colocated jobs or partitioned broadcast jobs.
clientAddress	Optional A socket address of a thin client that submitted a job.

type

Type of the compute job. Could be SINGLE, BROADCAST, MAP_REDUCE or DATA_RECEIVER.

Single job is the most common type, assigned to jobs that are executed on a single node. Broadcast jobs are executed on many nodes simultaneously.

className

Class name of a job.

jobId

Compute job ID.

targetNode

Name of the node where a job is executed.

initiatorNode
