This component uses the Mailchimp API to retrieve data and load it into a Redshift table. This stages the data, so the table is reloaded each time. You may then use transformations to enrich and manage the data in permanent tables.
Warning: This component is destructive as it truncates or recreates its target table on each run. Do not modify the target table structure manually.
|Name||Text||The descriptive name for the component.|
|Basic/Advanced Mode||Choice||Basic - This mode will build a Mailchimp Query for you using settings from Data Source, Data Selection and Data Source Filter parameters. In most cases, this will be sufficient.
Advanced - This mode will require you to write an SQL-like query which is translated into one or more Mailchimp API calls. The available fields and their descriptions are documented in the data model.
|Authentication Method||Choice||Select an authentication method. Mailchimp gives the opion of using OAuth or an API. Each requires a unique set of properties for the component.|
|Data Centre||Text||The Mailchimp data centre used. This is the last 4 digits of your API Key.|
|Data Source||Choice||Select a data source from a list that is generated using the completed authentication and connection properties.|
|Data Selection||Choice||Select one or more columns to return from the query.|
|Data Source Filter||Input Column||The available input columns vary depending upon the Data Source.|
|Qualifier||Is - Compares the column to the value using the comparator.
Not - Reverses the effect of the comparison, so "equals" becomes "not equals", "less than" becomes "greater than or equal to" etc.
|Comparator||Equals - The only supported comparator for Mailchimp is Equals.|
|Value||The value to be compared.|
|SQL||Text||Custom SQL-like query only available during 'Advanced' mode.|
|Combine Filters||Text||Use the defined filters in combination with one another according to either "and" or "or".|
|Limit||Number||Fetching a large number of results from Mailchimp will use multiple API calls. These calls are rate-limited by the provider, so fetching a very large number may result in errors.|
|Connection Options||Parameter||A JDBC parameter supported by the Database Driver. The available parameters are determined automatically from the driver, and may change from version to version.
They are usually not required as sensible defaults are assumed.
|Value||A value for the given Parameter.|
|S3 Staging Area||Text||The name of an S3 bucket for temporary storage. Ensure your access credentials have S3 access and permission to write to the bucket. See this document for details on setting up access. The temporary objects created in this bucket will be removed again after the load completes, they are not kept.|
|Schema||Select||Select the table schema. The special value, [Environment Default] will use the schema defined in the environment. For more information on using multiple schemas, see this article.|
|Target Table||Text||Provide a new table name.
Warning: This table will be recreated and will drop any existing table of the same name.
|Distribution Style||Select||Even - the default option, distribute rows around the Redshift Cluster evenly.
All - copy rows to all nodes in the Redshift Cluster.
Key - distribute rows around the Redshift cluster according to the value of a key column.
Table-distribution is critical to good performance - see the Amazon Redshift documentation for more information.
|Table Distribution Key||Select||This is only displayed if the Table Distribution Style is set to Key. It is the column used to determine which cluster node the row is stored on.|
|Sort Key||Select||This is optional, and specifies the columns from the input that should be set as the table's sort-key.
Sort-keys are critical to good performance - see the Amazon Redshift documentation for more information.
Additional OAuth Properties
|Authentication||Select||Select the set of credentials to use to connect to Mailchimp. These must be set up in advance, using Project → Manage OAuth.|
|Data Centre||Text||Provide an address for the desired Mailchimp server.|
Additional API Properties
|API Key||Select||This is only displayed if the Table Distribution Style is set to Key. It is the column used to determine which cluster node the row is stored on.|
This component makes the following values available to export into variables:
|Component||Name of the component.|
|Status||Successful or Unsuccessful.|
|Started At||Time Component began.|
|Completed At||Time Component finished.|
|Duration||Duration of Component's run.|
|Row Count||Number of Rows queried by the component.|
|Message||Any messages yielded by the component (usually empty).
Connect to the target database and issue the query. Stream the results into objects on S3. Then create or truncate the target table and issue a COPY command to load the S3 objects into the table. Finally, clean up the temporary S3 objects.
This example uses the Mailchimp Query Component to copy data from a Mailchimp server, to an S3 Bucket and then finally load the data into a Redshift table. The table itself is created by the Create/Replace Table Component and is called 'Campaign_Details'.
The Mailchimp properties are set up to use an API Key as the Authentication Method. An API key taken from the Mailchimp account is entered and the Data Selection property will automatically load and display any available data connected to the account, from which we select CampaignFeedback. The Mailchimp Query Component will then put this data onto the specified S3 Bucket and from there load the data into the Redshift table specified in the Target Table property.
