Terraform module to deploy an instance of Amazon Athena on AWS.

Tip

πŸ‘½ Use Atmos with Terraform

Cloud Posse uses atmos to easily orchestrate multiple environments using Terraform.
Works with Github Actions, Atlantis, or Spacelift.

Watch demo of using Atmos with Terraform
Example of running atmos to manage infrastructure from our Quick Start tutorial.

Usage

For a complete example, see examples/complete.

For automated tests of the complete example using bats and Terratest (which tests and deploys the example on AWS), see test.

# Create a standard label resource. See [null-label](https://github.com/cloudposse/terraform-null-label/#terraform-null-label--)
module "label" {
  source  = "cloudposse/label/null"
  # Cloud Posse recommends pinning every module to a specific version, though usually you want to use the current one
  # version = "x.x.x"

  namespace = "eg"
  name      = "example"
}

module "athena" {
  source  = "cloudposse/athena/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version = "x.x.x"

  context = module.label.this
}

Important

In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic approach for updating versions to avoid unexpected changes.

Makefile Targets

Requirements

Name Version

Providers

Name Version
aws >= 4.0

Modules

Name Source Version
this cloudposse/label/null 0.25.0

Resources

Name Type
aws_athena_data_catalog.default resource
aws_athena_database.default resource
aws_athena_named_query.default resource
aws_athena_workgroup.default resource
aws_kms_key.default resource
aws_s3_bucket.default resource

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
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,

"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 Athena query results bool true no
data_catalogs Map of Athena data catalogs and related configuration. map(any) n/a yes
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
named_queries Map of Athena named queries and related configuration. map(map(string)) n/a yes
namespace ID element. Usually an abbreviation of your organization name, e.g. 'eg' or 'cp', to help ensure generated IDs are globally unique string null no
publish_cloudwatch_metrics_enabled Boolean whether Amazon CloudWatch metrics are enabled for the workgroup. bool true no
regex_replace_chars Terraform regular expression (regex) string.
Characters matching the regex will be removed from the ID elements.
If not set, "/[^a-zA-Z0-9-]/" is used to remove all characters other than hyphens, letters and digits.
string null no
requester_pays_enabled Boolean whether to enable Requester Pays option on the Athena workgroup. bool false no
s3_output_path The S3 bucket path used to store query results. string "" no
stage ID element. Usually used to indicate role, e.g. 'prod', 'staging', 'source', 'build', 'test', 'deploy', 'release' string null no
tags Additional tags (e.g. {'BusinessUnit': 'XYZ'}).
Neither the tag keys nor the tag values will be modified by this module.
map(string) {} no
tenant ID element _(Rarely used, not included by default)_. A customer identifier, indicating who this instance of a resource is for string null no
workgroup_description A description the of Athena workgroup. string "" no
workgroup_encryption_option Indicates whether Amazon S3 server-side encryption with Amazon S3-managed keys (SSE_S3), server-side encryption with KMS-managed keys (SSE_KMS), or client-side encryption with KMS-managed keys (CSE_KMS) is used. string "SSE_KMS" no
workgroup_force_destroy The option to delete the workgroup and its contents even if the workgroup contains any named queries. bool false no
