Field Summary

Fields

Modifier and Type	Field	Description
static String	DEFAULT_TIME_FORMAT
static String	DEFAULT_TIMESTAMP_PRECISION
static 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.
static long	MIN_SHRINK_INTERVAL
static TSStatus	SUCCESS_STATUS
static int	THRIFT_DEFAULT_BUF_CAPACITY	How big should the default read and write buffers be? Defaults to 1KB
static 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.

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

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.
