DynamoDB Transactions

DynamoDB Transactions

DynamoDB Transactions:

• ACID Transactions (Atomic, Consistent, Isolated, Durable)
  • Atomic: all or nothing
  • Consistent: valid transaction that must leave database in valid state
    • prevents DB corruption or integrity issues
  • Isolated: no dependency between different transactions
  • Durable: when a transaction has been committed, it will remain committed even after system failure or power loss; written to disk instead of held in memory
  • Great for mission critical systems
• Read or write multiple items across multiple tables as an all or nothing operation
• Check for pre-requisite condition before writing to a table
• Complex business logic for single transactions
  • multiple steps
  • conditional
