public static boolean WRITE_COMPRESS

READ_DECOMPRESS

public static boolean READ_DECOMPRESS

SOCKET_SEND_BUFFER_BYTES

public static int SOCKET_SEND_BUFFER_BYTES

The optimal size for receive buffer and send buffer should be latency * network_bandwidth. Assuming latency = 1ms, network_bandwidth = 10Gbps buffer size should be ~ 1.25MB Reduce the buffer size can reduce the memory usage

SOCKET_RECV_BUFFER_BYTES

public static int SOCKET_RECV_BUFFER_BYTES

MAX_BLOCK_BYTES

public static int MAX_BLOCK_BYTES

COLUMN_BUFFER_BYTES

public static int COLUMN_BUFFER_BYTES

DATA_TYPE_CACHE_SIZE

public static int DATA_TYPE_CACHE_SIZE
