This module provides the necessary Terraform IaC to deploy a complete configurable DynamoDb table. This module does not (yet) provide auto-scaling for the table.

This table was generated using the command terraform-docs markdown ., given the terraform-docs library.

• resource dynamodb table
• Global Secondary Index (good exaplanation with example).
• Local Secondary Index
• Time To Live
• DynamoDB stream - what, why and how
• point in time recovery
• a similar library

• A word about attributes - following the docs - only define attributes on the table object that are going to be used as:

  • Table hash key or range key
  • LSI or GSI hash key or range key

• The defintion of ddb-attributes (extra attributes besides hash and range), is only valid if these attributes are used by GSI or LSI.

  • Note that it is not necessary to define these attributes upon creating the table. It is possible to define them upon writing to the table.

  • The DynamoDB table creation requires only the definition of the SCHEMA. This implies the definition of all the relevant query keys, such as the DDb partition and range keys; the LSI index key; and the GSI partition and range keys.

• Possible improvements:

  • how to perform input validation
