This component is responsible for provisioning an Amazon Athena workgroup, databases, and related resources.

Usage

Stack Level: Regional

Here are some example snippets for how to use this component:

stacks/catalog/athena/defaults.yaml file (base component for all Athena deployments with default settings):

  terraform:
    athena/defaults:

      metadata:
        component: athena
        inherits:
          - athena/defaults
      vars:
        enabled: true

        database:
          - example_db_1
          - example_db_2

CloudTrail Integration

Using Athena with CloudTrail logs is a powerful way to enhance your analysis of AWS service activity. This component supports creating a CloudTrail table for each account and setting up queries to read CloudTrail logs from a centralized location.

To set up the CloudTrail Integration, first create the create and alter queries in Athena with this component. When var.cloudtrail_database is defined, this component will create these queries.

import:
  - catalog/athena/defaults

components:
  terraform:
    athena/audit:
      metadata:
        component: athena
        inherits:
          - athena/defaults
      vars:
        enabled: true
        name: athena-audit
        workgroup_description: "Athena Workgroup for Auditing"
        cloudtrail_database: audit
        databases:
          audit:
            comment: "Auditor database for Athena"
            properties: {}
        named_queries:
          platform_dev:
            database: audit
            description: "example query against CloudTrail logs"
            query: |
              SELECT
               useridentity.arn,
               eventname,
               sourceipaddress,
               eventtime
              FROM %s.platform_dev_cloudtrail_logs
              LIMIT 100;

Once those are created, run the create and then the alter queries in the AWS Console to create and then fill the tables in Athena.

:::info

Athena runs queries with the permissions of the user executing the query. In order to be able to query CloudTrail logs, the audit account must have access to the KMS key used to encrypt CloudTrails logs. Set var.audit_access_enabled to true in the cloudtrail component

Inputs

Name	Description	Type	Default	Required
additional_tag_map	Additional key-value pairs to add to each map in tags_as_list_of_maps. Not added to tags or id. This is for some rare cases where resources want additional configuration of tags and therefore take a list of maps with tag key, value, and additional configuration.	map(string)	{}	no
athena_kms_key	Use an existing KMS key for Athena if create_kms_key is false.	string	null	no
athena_kms_key_deletion_window	KMS key deletion window (in days).	number	7	no
athena_s3_bucket_id	Use an existing S3 bucket for Athena query results if create_s3_bucket is false.	string	null	no
attributes	ID element. Additional attributes (e.g. workers or cluster) to add to id, in the order they appear in the list. New attributes are appended to the end of the list. The elements of the list are joined by the delimiter and treated as a single ID element.	list(string)	[]	no
bytes_scanned_cutoff_per_query	Integer for the upper data usage limit (cutoff) for the amount of bytes a single query in a workgroup is allowed to scan. Must be at least 10485760.	number	null	no
cloudtrail_bucket_component_name	The name of the CloudTrail bucket component	string	"cloudtrail-bucket"	no
cloudtrail_database	The name of the Athena Database to use for CloudTrail logs. If set, an Athena table will be created for the CloudTrail trail.	string	""	no
context	Single object for setting entire context at once. See description of individual variables for details. Leave string and numeric variables as null to use default value. Individual variable settings (non-null) override settings in context object, except for attributes, tags, and additional_tag_map, which are merged.	any	{ "additional_tag_map": {}, "attributes": [], "delimiter": null, "descriptor_formats": {}, "enabled": true, "environment": null, "id_length_limit": null, "label_key_case": null, "label_order": [], "label_value_case": null, "labels_as_tags": [ "unset" ], "name": null, "namespace": null, "regex_replace_chars": null, "stage": null, "tags": {}, "tenant": null }	no
create_kms_key	Enable the creation of a KMS key used by Athena workgroup.	bool	true	no
create_s3_bucket	Enable the creation of an S3 bucket to use for Athena query results	bool	true	no
data_catalogs	Map of Athena data catalogs and parameters	map(any)	{}	no
databases	Map of Athena databases and related configuration.	map(any)	n/a	yes
delimiter	Delimiter to be used between ID elements. Defaults to - (hyphen). Set to "" to use no delimiter at all.	string	null	no
descriptor_formats	Describe additional descriptors to be output in the descriptors output map. Map of maps. Keys are names of descriptors. Values are maps of the form {<br> format = string<br> labels = list(string)<br>} (Type is any so the map values can later be enhanced to provide additional options.) format is a Terraform format string to be passed to the format() function. labels is a list of labels, in order, to pass to format() function. Label values will be normalized before being passed to format() so they will be identical to how they appear in id. Default is {} (descriptors output will be empty).	any	{}	no
enabled	Set to false to prevent the module from creating any resources	bool	null	no
enforce_workgroup_configuration	Boolean whether the settings for the workgroup override client-side settings.	bool	true	no
environment	ID element. Usually used for region e.g. 'uw2', 'us-west-2', OR role 'prod', 'staging', 'dev', 'UAT'	string	null	no
id_length_limit	Limit id to this many characters (minimum 6). Set to 0 for unlimited length. Set to null for keep the existing setting, which defaults to 0. Does not affect id_full.	number	null	no
label_key_case	Controls the letter case of the tags keys (label names) for tags generated by this module. Does not affect keys of tags passed in via the tags input. Possible values: lower, title, upper. Default value: title.	string	null	no
label_order	The order in which the labels (ID elements) appear in the id. Defaults to ["namespace", "environment", "stage", "name", "attributes"]. You can omit any of the 6 labels ("tenant" is the 6th), but at least one must be present.	list(string)	null	no
label_value_case	Controls the letter case of ID elements (labels) as included in id, set as tag values, and output by this module individually. Does not affect values of tags passed in via the tags input. Possible values: lower, title, upper and none (no transformation). Set this to title and set delimiter to "" to yield Pascal Case IDs. Default value: lower.	string	null	no
labels_as_tags	Set of labels (ID elements) to include as tags in the tags output. Default is to include all labels. Tags with empty values will not be included in the tags output. Set to [] to suppress all generated tags. Notes: The value of the name tag, if included, will be the id, not the name. Unlike other null-label inputs, the initial setting of labels_as_tags cannot be changed in later chained modules. Attempts to change it will be silently ignored.	set(string)	[ "default" ]	no
name	ID element. Usually the component or solution name, e.g. 'app' or 'jenkins'. This is the only ID element not also included as a tag. The "name" tag is set to the full id string. There is no tag with the value of the name input.	string	null	no
