Member Function Documentation

◆ GetStats()

ColumnStatistics & duckdb::TableStatistics::GetStats	(	TableStatisticsLock &	lock,
		idx_t	i
	)

Get a reference to the stats - this requires us to hold the lock. The reference can only be safely accessed while the lock is held

◆ GetTableSample()

unique_ptr< BlockingSample > duckdb::TableStatistics::GetTableSample ( TableStatisticsLock & lock )

Get a reference to the table sample - this requires us to hold the lock.

Take ownership of the sample, needed for merging. Requires the lock

The documentation for this class was generated from the following file:
