  - DATA_PORT
```
public static final ConfigOption<Integer> DATA_PORT
```
    The default network port the task manager expects to receive transfer envelopes on. The 0 means that the TaskManager searches for a free port.
  - DATA_SSL_ENABLED
```
public static final ConfigOption<Boolean> DATA_SSL_ENABLED
```
    Config parameter to override SSL support for taskmanager's data transport.
  - BLOCKING_SHUFFLE_COMPRESSION_ENABLED
```
public static final ConfigOption<Boolean> BLOCKING_SHUFFLE_COMPRESSION_ENABLED
```
    Boolean flag indicating whether the shuffle data will be compressed for blocking shuffle mode.
    Note: Data is compressed per buffer and compression can incur extra CPU overhead so it is more effective for IO bounded scenario when data compression ratio is high. Currently, shuffle data compression is an experimental feature and the config option can be changed in the future.
  - SHUFFLE_COMPRESSION_CODEC
```
public static final ConfigOption<String> SHUFFLE_COMPRESSION_CODEC
```
    The codec to be used when compressing shuffle data.
  - NETWORK_DETAILED_METRICS
```
public static final ConfigOption<Boolean> NETWORK_DETAILED_METRICS
```
    Boolean flag to enable/disable more detailed metrics about inbound/outbound network queue lengths.
  - NETWORK_NUM_BUFFERS
```
@Deprecated
public static final ConfigOption<Integer> NETWORK_NUM_BUFFERS
```
    已过时。 use TaskManagerOptions.NETWORK_MEMORY_FRACTION, TaskManagerOptions.NETWORK_MEMORY_MIN, and TaskManagerOptions.NETWORK_MEMORY_MAX instead
    
    Number of buffers used in the network stack. This defines the number of possible tasks and shuffles.
  - NETWORK_BUFFERS_MEMORY_FRACTION
```
@Deprecated
public static final ConfigOption<Float> NETWORK_BUFFERS_MEMORY_FRACTION
```
    已过时。 use TaskManagerOptions.NETWORK_MEMORY_FRACTION instead
    
    Fraction of JVM memory to use for network buffers.
  - NETWORK_BUFFERS_MEMORY_MIN
```
@Deprecated
public static final ConfigOption<String> NETWORK_BUFFERS_MEMORY_MIN
```
    已过时。 use TaskManagerOptions.NETWORK_MEMORY_MIN instead
    
    Minimum memory size for network buffers.
  - NETWORK_BUFFERS_MEMORY_MAX
```
@Deprecated
public static final ConfigOption<String> NETWORK_BUFFERS_MEMORY_MAX
```
    已过时。 use TaskManagerOptions.NETWORK_MEMORY_MAX instead
    
    Maximum memory size for network buffers.
  - NETWORK_BUFFERS_PER_CHANNEL
```
public static final ConfigOption<Integer> NETWORK_BUFFERS_PER_CHANNEL
```
    Number of network buffers to use for each outgoing/incoming channel (subpartition/input channel).
    Reasoning: 1 buffer for in-flight data in the subpartition + 1 buffer for parallel serialization.
  - NETWORK_EXTRA_BUFFERS_PER_GATE
```
public static final ConfigOption<Integer> NETWORK_EXTRA_BUFFERS_PER_GATE
```
    Number of extra network buffers to use for each outgoing/incoming gate (result partition/input gate).
  - NETWORK_EXCLUSIVE_BUFFERS_REQUEST_TIMEOUT_MILLISECONDS
```
public static final ConfigOption<Long> NETWORK_EXCLUSIVE_BUFFERS_REQUEST_TIMEOUT_MILLISECONDS
```
    The timeout for requesting exclusive buffers for each channel.
  - NETWORK_BLOCKING_SHUFFLE_TYPE
```
public static final ConfigOption<String> NETWORK_BLOCKING_SHUFFLE_TYPE
```
  - NUM_ARENAS
```
public static final ConfigOption<Integer> NUM_ARENAS
```
  - NUM_THREADS_SERVER
```
public static final ConfigOption<Integer> NUM_THREADS_SERVER
```
  - NUM_THREADS_CLIENT
```
public static final ConfigOption<Integer> NUM_THREADS_CLIENT
```
  - CONNECT_BACKLOG
```
public static final ConfigOption<Integer> CONNECT_BACKLOG
```
  - CLIENT_CONNECT_TIMEOUT_SECONDS
```
public static final ConfigOption<Integer> CLIENT_CONNECT_TIMEOUT_SECONDS
```
  - SEND_RECEIVE_BUFFER_SIZE
```
public static final ConfigOption<Integer> SEND_RECEIVE_BUFFER_SIZE
```
  - TRANSPORT_TYPE
```
public static final ConfigOption<String> TRANSPORT_TYPE
```
  - NETWORK_REQUEST_BACKOFF_INITIAL
```
public static final ConfigOption<Integer> NETWORK_REQUEST_BACKOFF_INITIAL
```
    Minimum backoff for partition requests of input channels.
  - NETWORK_REQUEST_BACKOFF_MAX
```
public static final ConfigOption<Integer> NETWORK_REQUEST_BACKOFF_MAX
```
    Maximum backoff for partition requests of input channels.
  - FORCE_PARTITION_RELEASE_ON_CONSUMPTION
```
public static final ConfigOption<Boolean> FORCE_PARTITION_RELEASE_ON_CONSUMPTION
```
