Build a SSTable

成员函数说明

build()

RC oceanbase::ObSSTableBuilder::build	(	shared_ptr< ObMemTable >	mem_table,
		const string &	file_name,
		uint32_t	sst_id
	)

Builds an SSTable from the provided in-memory table and stores it in a file.

This function takes an ObMemTable as input, partitions the data into blocks, serializes the blocks, and writes them into an SSTable file.

参数

mem_table	A shared pointer to the ObMemTable containing the data to be written into the SSTable.
file_name	The name of the file where the constructed SSTable will be stored.
sst_id	A unique identifier assigned to the created SSTable.

返回

RC A result code indicating the success or failure of the SSTable creation process.
