Package io.trino.plugin.thrift.api.datatypes

Class TrinoThriftHyperLogLog

java.lang.Object

io.trino.plugin.thrift.api.datatypes.TrinoThriftHyperLogLog

All Implemented Interfaces:

TrinoThriftColumnData

@ThriftStruct
public final class TrinoThriftHyperLogLog
extends Object
implements TrinoThriftColumnData

Elements of nulls array determine if a value for a corresponding row is null. Each elements of sizes array contains the length in bytes for the corresponding element. If row is null then the corresponding element in sizes is ignored. bytes array contains encoded byte values for HyperLogLog representation as defined in Airlift specification: href="https://github.com/airlift/airlift/blob/master/stats/docs/hll.md Values for all rows are written to bytes array one after another. The total number of bytes must be equal to the sum of all sizes.
