[−]

Encapsulate the kvrpcpb::Context to provide some extra properties.

Fields

tag: ReqTag
[−]

The tag of the request

context: Context
[−]

The rpc context carried in the request

ranges: Vec<KeyRange>
[−]

Scan ranges of this request

deadline: Deadline
[−]

The deadline of the request

peer: Option<String>
[−]

The peer address of the request

is_desc_scan: Option<bool>
[−]

Whether the request is a descending scan (only applicable to DAG)

txn_start_ts: TimeStamp
[−]

The transaction start_ts of the request

bypass_locks: TsSet
[−]

The set of timestamps of locks that can be bypassed during the reading.

cache_match_version: Option<u64>
[−]

The data version to match. If it matches the underlying data version, request will not be processed (i.e. cache hit).

None means don’t try to hit the cache.

lower_bound: Vec<u8>
[−]

The lower bound key in ranges of the request

upper_bound: Vec<u8>
[−]

The upper bound key in ranges of the request

perf_level: PerfLevel
[−]

Perf level
