构造器详细资料

WriteBufferManager

public WriteBufferManager(long bufferSizeBytes,
                          Cache cache,
                          boolean allowStall)

Construct a new instance of WriteBufferManager.

Check https://github.com/facebook/rocksdb/wiki/Write-Buffer-Manager for more details on when to use it

参数:

bufferSizeBytes - buffer size(in bytes) to use for native write_buffer_manager

cache - cache whose memory should be bounded by this write buffer manager

allowStall - if set true, it will enable stalling of writes when memory_usage() exceeds buffer_size. It will wait for flush to complete and memory usage to drop down.

WriteBufferManager

public WriteBufferManager(long bufferSizeBytes,
                          Cache cache)

allowStall

public boolean allowStall()

disposeInternal
