### Publish Connector Locally

Source: https://github.com/zeenea/public-connector-sdk/blob/main/README.md

Command to publish the connector package to the local Maven repository for use in other projects.

```shell
./gradelw publishToMavenLocal
```

### Implement the Connector interface

Source: https://github.com/zeenea/public-connector-sdk/blob/main/README.md

The Connector interface acts as a factory for creating connection instances. Ensure the class is annotated with @Extension for proper discovery.

```java
package com.example.connector;

import zeenea.connector.Connection;
import zeenea.connector.ConnectionConfiguration;
import zeenea.connector.Connector;
import zeenea.connector.exception.InvalidConfigurationException;

@Extension
public class ExampleConnector implements Connector {
    public String getConnectorId() {
        // Used to select the connector
        return "example";
    }

    public Connection newConnection(ConnectionConfiguration connectionConfiguration) throws InvalidConfigurationException {
        // Configuration validation might be performed here
        // Invalid configuration is best conveyed by throwing an InvalidConfigurationException
        return connector;
    }
}
```

--------------------------------

### Define plugin properties

Source: https://github.com/zeenea/public-connector-sdk/blob/main/README.md

A plugin.properties file is required for PF4J to identify and load the connector plugin.

```properties
plugin.id=example-plugin
plugin.provider=Example
plugin.version=1.0.0
```

### Implement a SynchronizeConnection

Source: https://github.com/zeenea/public-connector-sdk/blob/main/README.md

Defines a custom connection class by implementing the SynchronizeConnection interface to synchronize items like visualizations and fields.

```java
package com.example.connector;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import zeenea.connector.Connection;
import zeenea.connector.synchronize.SynchronizeConnection;
import zeenea.connector.contact.Contact;
import zeenea.connector.property.PropertyDefinition;
import zeenea.connector.property.StringPropertyDefinition;
import zeenea.connector.Item;
import zeenea.connector.visualization.Visualization;
import zeenea.connector.field.Field;
import zeenea.connector.common.ItemIdentifier;
import zeenea.connector.common.IdentificationProperty;
import zeenea.connector.common.ItemReference;

import java.time.Instant;
import java.util.*;
import java.util.stream.Stream;

public class ExampleConnection implements SynchronizeConnection {
  // slf4j might be used for logging
  private static final Logger LOGGER = LoggerFactory.getLogger(ExampleConnection.class);

  private static final StringPropertyDefinition TYPE_METADATA = PropertyDefinition.string("type", "Type of item");

  public Set<PropertyDefinition> getProperties() {
    // Value returned here can be dynamic and change over successive calls
    return new HashSet<>(Collections.singletonList(TYPE_METADATA));
  }

  @Override
  public Stream<Item> synchronize() {
    return Stream.of(
        Visualization.builder()
            .id(
                ItemIdentifier.of(
                    IdentificationProperty.of("type", "visualization"),
                    IdentificationProperty.of("report_id", "1234"),
                    IdentificationProperty.of("workspace_id", "4321")))
            .name("Visualization name")
            .description("Some description")
            .properties(PropertiesBuilder.create().put(TYPE_METADATA, "some type").build())
            .fields(
                List.of(
                    Field.builder()
                        .id(
                            ItemIdentifier.of(IdentificationProperty.of("field_key", "dim1")))
                        .name("dim1")
                        .dataType(DataType.String)
                        .nativeType("string")
                        .description("some field description")
                        .properties(
                            PropertiesBuilder.create().put(TYPE_METADATA, "dimension").build())
                        .sourceFields(List.of())
                        .build(),
                    Field.builder()
                        .id(
                            ItemIdentifier.of(IdentificationProperty.of("field_key", "mes1")))
                        .name("mes1")
                        .dataType(DataType.String)
                        .nativeType("string")
                        .description("some field description")
                        .properties(
                            PropertiesBuilder.create().put(TYPE_METADATA, "measure").build())
                        .sourceFields(
                            List.of(
                                ItemReference.of(
                                    ItemIdentifier.of(
                                        IdentificationProperty.of("id", "dataset2"),
                                        IdentificationProperty.of("field_key", "mes1")),
                                    ConnectionReferenceCode.of("hostname:port/database"))))
                        .build()))
            .sourceDatasets(
                List.of(
                    ItemReference.of(
                        ItemIdentifier.of(IdentificationProperty.of("id", "dataset2")),
                        ConnectionReferenceCode.of("hostname:port/database"))))
            .contactRelations(
                List.of(Contact.of("test@zeenea.com", "Some name", "0600000000", "Owner")))
            .build());
  }

  public void close() {
    // Resources previously opened can be closed here
  }
}
