GetItem
A DynamoDB operation that reads a single record by primary key, with latency as low as single-digit milliseconds, suited to key-lookup access patterns.
Timeline (last 90 days)
DynamoDB's GetItem takes a complete primary key and returns the corresponding single record (or nothing), and adding `--return-consumed-capacity TOTAL` displays the read capacity consumed by that request.
DynamoDB reads are eventually consistent by default; adding `--consistent-read` makes them strongly consistent reads that reflect all previously completed writes, but the consumed read capacity cost doubles.
DynamoDB single-item reads by primary key (GetItem) keep latency steady at single-digit milliseconds.
