ExecuteTransaction
Source:
src/AWS/DynamoDB/ExecuteTransaction.ts
Runtime binding for dynamodb:ExecuteTransaction.
Bind this operation to one or more tables inside a function runtime to get a
callable that runs a PartiQL transaction. Statements reference the bound
tables by their physical names (resolve them via table.tableName); the
host is granted the transactional read/write actions on every bound table.
Provide the ExecuteTransactionHttp layer on the Function to satisfy the
binding.
