Struct tikv::storage::mvcc::reader::scanner::ScannerBuilder [−][src]
Implementations
impl<S: Snapshot> ScannerBuilder<S>[src]
pub fn new(snapshot: S, ts: TimeStamp, desc: bool) -> Self[src]
Initialize a new ScannerBuilder
pub fn fill_cache(self, fill_cache: bool) -> Self[src]
Set whether or not read operations should fill the cache.
Defaults to true.
pub fn omit_value(self, omit_value: bool) -> Self[src]
Set whether values of the user key should be omitted. When omit_value is true, the
length of returned value will be 0.
Previously this option is called key_only.
Defaults to false.
pub fn isolation_level(self, isolation_level: IsolationLevel) -> Self[src]
Set the isolation level.
Defaults to IsolationLevel::Si.
pub fn range(self, lower_bound: Option<Key>, upper_bound: Option<Key>) -> Self[src]
Limit the range to [lower_bound, upper_bound) in which the ForwardKvScanner should scan.
None means unbounded.
Default is (None, None).
pub fn bypass_locks(self, locks: TsSet) -> Self[src]
Set locks that the scanner can bypass. Locks with start_ts in the specified set will be ignored during scanning.
Default is empty.
pub fn hint_min_ts(self, min_ts: Option<TimeStamp>) -> Self[src]
Set the hint for the minimum commit ts we want to scan.
Default is empty.
pub fn hint_max_ts(self, max_ts: Option<TimeStamp>) -> Self[src]
Set the hint for the maximum commit ts we want to scan.
Default is empty.
pub fn check_has_newer_ts_data(self, enabled: bool) -> Self[src]
Check whether there is data with newer ts. The result of met_newer_ts_data is Unknown
if this option is not set.
Default is false.
pub fn build(self) -> Result<Scanner<S>>[src]
Build Scanner from the current configuration.
pub fn build_entry_scanner(
self,
after_ts: TimeStamp,
output_delete: bool
) -> Result<EntryScanner<S>>[src]
self,
after_ts: TimeStamp,
output_delete: bool
) -> Result<EntryScanner<S>>
pub fn build_delta_scanner(
self,
from_ts: TimeStamp,
extra_op: ExtraOp
) -> Result<DeltaScanner<S>>[src]
self,
from_ts: TimeStamp,
extra_op: ExtraOp
) -> Result<DeltaScanner<S>>
