详细描述

Represents a data block in the LSM-Tree.

The ObBlock class manages a block of serialized key-value pairs, along with their offsets, for efficient storage and retrieval. It provides methods to decode serialized data, access individual entries, and create iterators for traversing the block contents.

成员函数说明

decode()

RC oceanbase::ObBlock::decode

(

const string &

data

)

Decodes serialized block data.

This function parses and decodes the serialized string data to reconstruct the block's structure, including all key-value offsets and entries. The decoded data format can reference ObBlockBuilder.

参数

data	The serialized block data as a string.

返回

RC The result code indicating the success or failure of the decode operation.
