DocumentDB Cluster, Encrypted and Auditable
A cluster whose two dangerous AWS defaults are inverted: storage encryption is hard-coded on because it cannot be added later, and the master password is never an input - Secrets Manager generates it, so it never reaches the state file.

Documentation
aws-documentdb
An Amazon DocumentDB cluster, its instances, subnet group and parameter group.
Works with Terraform and OpenTofu (>= 1.6), AWS provider
>= 6.0, < 7.0.
Two AWS defaults are wrong here, and this module inverts both.
storage_encrypteddefaults to false. A cluster written the obvious way is unencrypted at rest, and it cannot be encrypted afterwards - the only route is a snapshot restored into a new cluster, with the downtime that implies. This module hard-codes it on; it is not a variableskip_final_snapshotis how adestroytakes the data with it. It defaults off here, and a precondition refuses the one combination that leaves nothing behind:skip_final_snapshoton anddeletion_protectionoff
The master password is not an input. manage_master_user_password hands it
to Secrets Manager, which generates and rotates it. A password variable, however
carefully marked sensitive, is written into the state file in plain text, and
the state file is copied to wherever your backend lives. The secret's ARN is an
output.
Other defaults worth knowing:
audit_logson. Off, the question "what did that credential touch?" has no answer at all- Two instances, with
promotion_tierset from the index so a failover is predictable rather than whichever replica answers first - A precondition requires two or more subnets: a single-AZ cluster cannot fail over, and nothing in the AWS API says so at apply time
master_usernameis validated againstadminandroot, which DocumentDB reserves and rejects lateallow_major_version_upgradeoff: a major engine change is a migration, not a plan
Verification
Static validation runs tofu fmt, init, validate, tflint and checkov.
This module has not yet had a live test, so it is published as statically
validated with its live test pending and does not carry the live-tested mark.

- Usage
Related modules
aws-keyspaces
point_in_time_recovery defaults to DISABLED and Keyspaces has no snapshots or automated backups, so off means a dropped table is simply gone. PITR on, a customer-managed key, and the two one-way doors - client-side timestamps and TTL - named rather than set quietly.
aws-database-proxy
Amazon RDS Proxy in front of an RDS instance or Aurora cluster: TLS required, clients authenticate with IAM tokens while the proxy reads the password from Secrets Manager, through a role limited to those secrets. Debug logging writes SQL statement text to the logs, so it is off unless that is accepted. End-to-end IAM removes the stored password entirely.
aws-dax-cache
DynamoDB Accelerator with TLS and encryption at rest. DAX leaves both off by default, and neither can be turned on for an existing cluster, so a fix means a new cluster. This module also creates its own security group (DAX otherwise uses the VPC default), a service role limited to the named tables and their indexes, and states that writes bypassing DAX leave stale reads until the TTL.
aws-neptune
Neptune has no user, no password and no GRANT. Authorization is IAM and it defaults to OFF, so anything that can reach port 8182 can read every edge and drop the lot. IAM auth on, storage encrypted, and the audit log driven from one variable because its two halves live in different resources and either alone logs nothing.
aws-dms
ssl_mode defaults to none in AWS, so a task reads your entire production database and writes it elsewhere unencrypted. This defaults to require, refuses none unless stated, and pushes the credential into Secrets Manager rather than state.
aws-quicksight
A QuickSight subscription on Enterprise edition through IAM Identity Center, with admin, author and reader groups, termination protection on because unsubscribing deletes every dashboard, and a VPC connection with its own role so a private database stays private. The authentication method is permanent; Standard edition and QuickSight-managed users are accepted by name.
