详细描述

Abstract base class for compaction picker strategies in an LSM-Tree.

This class defines the interface for picking a compaction task from a set of SSTables. Derived classes will implement specific compaction strategies (e.g., tiered or leveled compaction).

构造及析构函数说明

ObCompactionPicker()

oceanbase::ObCompactionPicker::ObCompactionPicker ( ObLsmOptions *  options )

inline

参数

options

Pointer to the LSM-Tree options configuration.

成员函数说明

create()

ObCompactionPicker * oceanbase::ObCompactionPicker::create ( CompactionType  type, ObLsmOptions *  options  )

static

Static factory method to create a specific compaction picker.

参数

type	The type of compaction strategy (e.g., tiered, leveled).
options	Pointer to the LSM-Tree options configuration.

返回

A pointer to the created ObCompactionPicker instance.

pick()

virtual unique_ptr< ObCompaction > oceanbase::ObCompactionPicker::pick ( SSTablesPtr  sstables )

pure virtual

Pure virtual method to pick a compaction task.

参数

sstables

A pointer to the SSTables available for compaction.

返回

A unique pointer to the selected compaction task.

在 oceanbase::TiredCompactionPicker 内被实现.
