Field Detail

THRIFT_DEFAULT_BUF_CAPACITY

public static final int THRIFT_DEFAULT_BUF_CAPACITY

How big should the default read and write buffers be? Defaults to 1KB

See Also:

Constant Field Values

THRIFT_FRAME_MAX_SIZE

public static final int THRIFT_FRAME_MAX_SIZE

It is used to prevent the size of the parsing package from being too large and allocating the buffer will cause oom. Therefore, the maximum length of the requested memory is limited when reading. Thrift max frame size (16384000 bytes by default), we change it to 512MB.

Constant Field Values

MAX_BUFFER_OVERSIZE_TIME

public static final int MAX_BUFFER_OVERSIZE_TIME

if resizeIfNecessary is called continuously with a small size for more than MAX_BUFFER_OVERSIZE_TIME times, we will shrink the buffer to reclaim space.
