Enums

MetricLevel

Constants

MAX_BLOCK_CACHE_SHARD_BITS

MAX_CONNECTION_WINDOW_SIZE

Use the maximum value for HTTP/2 connection window size to avoid deadlock among multiplexed streams on the same connection.

MAX_META_CACHE_SHARD_BITS

MIN_BUFFER_SIZE_PER_SHARD

STREAM_WINDOW_SIZE

Use a large value for HTTP/2 stream window size to improve the performance of remote exchange, as we don’t rely on this for back-pressure.

Derive Macros

OverrideConfig

Sections in the configuration file can use #[derive(OverrideConfig)] to generate the implementation of overwriting configs from the file.
