Expand description

Feature flags supported or enabled by a client. This is intended to be sent as part of request metadata to assure the server that certain behaviors are safe to enable. This proto is meant to be serialized and websafe-base64 encoded under the bigtable-features metadata key. The value will remain constant for the lifetime of a client and due to HTTP2’s HPACK compression, the request overhead will be tiny. This is an internal implementation detail and should not be used by end users directly.

Fields§

§reverse_scans: bool

Notify the server that the client supports reverse scans. The server will reject ReadRowsRequests with the reverse bit set when this is absent.

§mutate_rows_rate_limit: bool

Notify the server that the client enables batch write flow control by requesting RateLimitInfo from MutateRowsResponse. Due to technical reasons, this disables partial retries.

§mutate_rows_rate_limit2: bool

Notify the server that the client enables batch write flow control by requesting RateLimitInfo from MutateRowsResponse. With partial retries enabled.

§last_scanned_row_responses: bool

Notify the server that the client supports the last_scanned_row field in ReadRowsResponse for long-running scans.

§routing_cookie: bool

Notify the server that the client supports using encoded routing cookie strings to retry requests with.

§retry_info: bool

Notify the server that the client supports using retry info back off durations to retry requests with.

§client_side_metrics_enabled: bool

Notify the server that the client has client side metrics enabled.
