New Features

Fusion Connectors

  • Fusion 5.6.1 adds a new connector, the Web V2 Connector. This brings our Web connector from the classic framework to our V2 framework.
    The Web V2 connector retrieves data from a Web site using HTTP and starting from a specified URL.
  • As part of our transition from Pulsar to Kafka, 5.6.1 returns the ability to Remotely Launch a Plugin.
Follow this configuration to use a remote connector in Fusion.
A known issue is after idling for five minutes without any new connector start requests, the remote connector stops responding to server requests and must restart. This causes connector start requests to hang. A workaround is to schedule a connector to run every three minutes. It is recommended to use a connector instance that doesn’t fetch any documents to keep the remote connector functional without frequent restarts.
  1. Execute the following command.
    java -jar connector-plugin-client-standalone.jar [YAML_CONFIG_FILE]
    
  2. Check that the YAML_CONFIG_FILE has the following format.
    kafka-bridge:
        target: mynamespace-connectors-backend.lucidworkstest.com:443 # mandatory
        plain-text: false # optional
        proxy-server: # optional - needed when a forward proxy server is used to provide outbound access to the standalone connector
        host: host
        port: 111
        user: user
        password: password
        trust: # optional - needed when the client’s system doesn’t trust the server’s certificate
        cert-collection-filepath: path1
    
    proxy: # mandatory fusion-proxy
    user: admin
    password: password123
    url: https://fusiontest.com/ # needed only when the connector plugin requires blob store access
    
    plugin: # mandatory
    path: ./fs.zip
    type:
        suffix: remote
    
  3. Use this table for descriptions of the YAML properties.
KeyValue description
kafka-bridge.targetThe Kafka-gRPC bridge host:port pair.
kafka-bridge.plain-textEnable when TLS ingress is not used.
kafka-bridge.proxy-server.hostThe Forward Proxy Server Host.
kafka-bridge.proxy-server.portThe Forward Proxy Server Port.
kafka-bridge.proxy-server.userThe Forward Proxy Server User.
kafka-bridge.proxy-server.passwordThe Forward Proxy Server Password.
kafka-bridge.trust.cert-collection-filepathThe Private Key file path.
proxy.urlFusion proxy url.
proxy.userFusion proxy user.
proxy.passwordFusion proxy password.
plugin.pathThe path of the plugin zip file.
plugin.typeOptional suffix added to the plugin id. For example, if the plugin id is lucidworks.test and the suffix is remote, the plugin will be launched with lucidworks.test.remote.
Example YAML_CONFIG_FILE:
kafka-bridge:
target: mynamespace-connectors.example.com:443
plain-text: false

proxy:
user: admin
password: "password123"

plugin:
path: ./testplugin.zip

Bug Fixes

Fusion

  • The blocked rule form now validates the “Parameter Name” when closing the modal. This fixes an error where blocked parameters in the Query Workbench could not be deleted via the UI.
  • User with read-only access no longer see the Quickstart splash page, as they are unable to use it to create applications or other Fusion objects.
The Quickstart is a wizard that lets you explore some of Fusion’s core capabilities:
  • Creating or selecting an app
  • Selecting a collection (where data is stored)
  • Indexing data
  • Searching
LucidAcademyLucidworks offers free training to help you get started.The Course for Using The Quickstart Wizard focuses on using the wizard to practice using the key functions of Fusion:

Your new app is selected by default.
  2. After selecting an app, click Continue. On the Select a Collection screen, you can select or create a collection for your quickstart data. A collection with the same name as your app is created automatically: quickstart-2
  3. Click Continue.
    On the Index Data screen, you can either select one of the built-in sample datasets or click Use my data to upload your own:
    quickstart-3
  4. Click Continue.
    On the Query Data screen, you can see all search results and enter your own search queries to test the indexed dataset. You can also select the display fields or view the parsed documents:
    quickstart-4
  5. Click Continue. quickstart-5 From here, you can do the following:
    • Open the Index Workbench to change the index pipeline.
    • Open the Query Workbench to change the query pipeline. The workbenches are essentials tools in the Fusion workflow.
    • Open App Studio to create a user interface for searching this collection.
      App Studio is only available in Fusion 4.1 and 4.2.
