HBASE_NETTY_ALLOCATOR_KEY

public static final String HBASE_NETTY_ALLOCATOR_KEY

Name of property to change the byte buf allocator for the netty channels. Default is no value, which causes us to use PooledByteBufAllocator. Valid settings here are "pooled", "unpooled", and "heap", or, the name of a class implementing ByteBufAllocator.

"pooled" and "unpooled" may prefer direct memory depending on netty configuration, which is controlled by platform specific code and documented system properties.

"heap" will prefer heap arena allocations.

POOLED_ALLOCATOR_TYPE

static final String POOLED_ALLOCATOR_TYPE

See Also:

• Constant Field Values

UNPOOLED_ALLOCATOR_TYPE

static final String UNPOOLED_ALLOCATOR_TYPE

HEAP_ALLOCATOR_TYPE

static final String HEAP_ALLOCATOR_TYPE

See Also:

• Constant Field Values

CHANNEL_WRITABLE_LOW_WATERMARK_KEY

public static final String CHANNEL_WRITABLE_LOW_WATERMARK_KEY

Low watermark for pending outbound bytes of a single netty channel. If the high watermark was exceeded, channel will have setAutoRead to true again. The server will start reading incoming bytes (requests) from the client channel.

See Also:

• Constant Field Values

CHANNEL_WRITABLE_LOW_WATERMARK_DEFAULT

private static final int CHANNEL_WRITABLE_LOW_WATERMARK_DEFAULT

See Also:

• Constant Field Values

CHANNEL_WRITABLE_HIGH_WATERMARK_KEY

public static final String CHANNEL_WRITABLE_HIGH_WATERMARK_KEY

High watermark for pending outbound bytes of a single netty channel. If the number of pending outbound bytes exceeds this threshold, setAutoRead will be false for the channel. The server will stop reading incoming requests from the client channel.

Note: any requests already in the call queue will still be processed.

See Also:

• Constant Field Values

CHANNEL_WRITABLE_HIGH_WATERMARK_DEFAULT

private static final int CHANNEL_WRITABLE_HIGH_WATERMARK_DEFAULT

See Also:

• Constant Field Values

CHANNEL_WRITABLE_FATAL_WATERMARK_KEY

public static final String CHANNEL_WRITABLE_FATAL_WATERMARK_KEY

Fatal watermark for pending outbound bytes of a single netty channel. If the number of pending outbound bytes exceeds this threshold, the connection will be forcibly closed so that memory can be reclaimed. The client will have to re-establish a new connection and retry any in-flight requests.

Note: must be higher than the high watermark, otherwise it's ignored.
