ConnectorContext Class

ConnectorContext

The ConnectorContext class is a part of the org.sunbird.obsrv.connector.model package. It encapsulates the context information for a connector instance, including its configuration, state, and statistics. This class is essential for managing the lifecycle and execution of connector instances within the Obsrv platform.

Class Definition

package org.sunbird.obsrv.connector.model

import com.fasterxml.jackson.annotation.{JsonIgnore, JsonProperty}
import org.sunbird.obsrv.job.model.Models.ErrorData

object Models {

  case class ConnectorContext(
     @JsonProperty("connector_id") connectorId: String,
     @JsonProperty("dataset_id") datasetId: String,
     @JsonProperty("connector_instance_id") connectorInstanceId: String,
     @JsonProperty("connector_type") connectorType: String,
     @JsonIgnore entryTopic: String,
     @JsonIgnore state: ConnectorState,
     @JsonIgnore stats: ConnectorStats
   )
}

Fields

connectorId: String

• Description: The unique identifier for the connector.

• Annotations: @JsonProperty("connector_id")

datasetId: String

• Description: The unique identifier for the dataset associated with the connector.

• Annotations: @JsonProperty("dataset_id")

connectorInstanceId: String

• Description: The unique identifier for the specific instance of the connector.

• Annotations: @JsonProperty("connector_instance_id")

connectorType: String

• Description: The type of the connector (e.g., source, sink).

• Annotations: @JsonProperty("connector_type")

entryTopic: String

• Description: The entry topic for the connector. This field is ignored during JSON serialization.

• Annotations: @JsonIgnore

state: ConnectorState

• Description: The state of the connector instance, encapsulated in a ConnectorState object. This field is ignored during JSON serialization.
• Annotations: @JsonIgnore

stats: ConnectorStats

• Description: The statistics of the connector instance, encapsulated in a ConnectorStats object. This field is ignored during JSON serialization.
• Annotations: @JsonIgnore

Usage

The ConnectorContext class is used to manage and track the state and statistics of a connector instance. It provides a structured way to access and manipulate the context information required for the execution of connectors.

Example

import org.sunbird.obsrv.connector.model.Models.ConnectorContext
import org.sunbird.obsrv.connector.model.{ConnectorState, ConnectorStats}
import org.sunbird.obsrv.job.util.PostgresConnectionConfig

implicit val postgresConfig: PostgresConnectionConfig = // initialize config

val state = new ConnectorState("connectorInstanceId", None)
val stats = new ConnectorStats("connectorInstanceId", None)

val context = ConnectorContext(
  connectorId = "connectorId",
  datasetId = "datasetId",
  connectorInstanceId = "connectorInstanceId",
  connectorType = "source",
  entryTopic = "entryTopic",
  state = state,
  stats = stats
)

// Accessing context fields
println(context.connectorId)
println(context.datasetId)
