CompactionOptionsFIFO

public CompactionOptionsFIFO()

方法详细资料

setMaxTableFilesSize

public CompactionOptionsFIFO setMaxTableFilesSize(long maxTableFilesSize)

Once the total sum of table files reaches this, we will delete the oldest table file

Default: 1GB

参数:

maxTableFilesSize - The maximum size of the table files

返回:

the reference to the current options.

maxTableFilesSize

public long maxTableFilesSize()

Once the total sum of table files reaches this, we will delete the oldest table file

Default: 1GB

返回:

max table file size in bytes

setAllowCompaction

public CompactionOptionsFIFO setAllowCompaction(boolean allowCompaction)

If true, try to do compaction to compact smaller files into larger ones. Minimum files to compact follows options.level0_file_num_compaction_trigger and compaction won't trigger if average compact bytes per del file is larger than options.write_buffer_size. This is to protect large files from being compacted again.

Default: false

参数:

allowCompaction - true to allow intra-L0 compaction

返回:

the reference to the current options.

allowCompaction

public boolean allowCompaction()

Check if intra-L0 compaction is enabled. When enabled, we try to compact smaller files into larger ones.

See setAllowCompaction(boolean).

Default: false

返回:

true if intra-L0 compaction is enabled, false otherwise.

disposeInternal

protected final void disposeInternal(long handle)

指定者:

disposeInternal 在类中 RocksObject
