1.19.0 (2022-01-25)


  • storage: add fully configurable and idempotency-aware retry strategy (#5384, #5185, #5170, #5223, #5221, #5193, #5159, #5165, #5166, #5210, #5172, #5314)
    • This release contains changes to fully align this library's retry strategy with best practices as described in the Cloud Storage docs.
    • The library will now retry only idempotent operations by default. This means that for certain operations, including object upload, compose, rewrite, update, and delete, requests will not be retried by default unless idempotency conditions for the request have been met.
    • The library now has methods to configure aspects of retry policy for API calls, including which errors are retried, the timing of the exponential backoff, and how idempotency is taken into account.
    • If you wish to re-enable retries for a non-idempotent request, use the RetryAlways policy.
    • For full details on how to configure retries, see the package docs and the Cloud Storage docs
