Struct TkStreamSetBuilder

Source 
pub struct TkStreamSetBuilder { /* private fields */ }
Expand description

A TkStreamSetBuilder is used to create a TkStreamSet with clear configuration.

Implementations§

Source§

impl TkStreamSetBuilder

Source

pub fn new() -> TkStreamSetBuilder

Create a new instance of the builder with default configuration.

Source

pub async fn build(self) -> TkssResult<TkStreamSet>

Create an instance while consuming the builder

Default the rest of the configuration.

Source

pub fn with_memory_limit(self, limit: MemoryLimit) -> TkStreamSetBuilder

Set the memory limit for the stream set.

If not set, the limit will be set to MemoryLimit::VeryLow. If set, the limit will be enforced with best effort. The limit is a soft limit and may be exceeded in some cases by a relatively small margin, ~5%.

Source

pub fn with_working_dir(self, dir: PathBuf) -> TkStreamSetBuilder

Set the working directory for the stream set.

If not set, a temporary directory will be created and cleaned up on process exit. If set, the directory must exist and be writable.

Source

pub fn with_segment_time_interval( self, interval: Duration, ) -> TkStreamSetBuilder

Set the segment time interval for the stream set. This determines the size of the time-keyed segments that need to be loaded into memory to perform deduplication of a batch insert.

If not set, the interval will be set to 1 hour. If set, the interval will be enforced.

Source

pub fn with_segment_retention_period( self, period: Duration, ) -> TkStreamSetBuilder

Set the segment retention period for the stream set. This determines how long time-keyed segments are kept on disk (even if inactive or small). This period is enforced while inserting data into the stream set.

If not set, the retention period will be set to 7 days. If set, the retention period will be enforced.
