Capabilities

The current capabilities for target-redshift may have been automatically set when originally added to the Hub. Please review the capabilities when using this loader. If you find they are out of date, please consider updating them by making a pull request to the YAML file that defines the capabilities for this loader.

This plugin has the following capabilities:

  • about
  • hard-delete
  • schema-flattening
  • stream-maps

You can override these capabilities or specify additional ones in your meltano.yml by adding the capabilities key.

Settings

This target uses boto3 to connect to AWS and perform copy and possibly credential operations. The agent running this target should be connected to AWS to be able to open a boto3 client.

The target-redshift settings that are known to Meltano are documented below. To quickly find the setting you're looking for, click on any setting name from the list:

You can also list these settings using 

meltano config
with the list subcommand: 

meltano config target-redshift list

You can override these settings or specify additional ones in your meltano.yml by adding the settings key.

Please consider adding any settings you have defined locally to this definition on MeltanoHub by making a pull request to the YAML file that defines the settings for this plugin.
