Field Detail

MAX_STACK_DEPTH

Constant Field Values

MAX_STACK_SIZE

public static final int MAX_STACK_SIZE

See Also:

Constant Field Values

MAX_ENCODED_BYTES

public static final int MAX_ENCODED_BYTES

Collector has a 1000000 byte limit on the Content-Length in the HttpServletRequest

See Also:

Constant Field Values

MAX_ENCODED_DATA_BYTES

public static final int MAX_ENCODED_DATA_BYTES

The maximum size of the JSON payload itself (excluding data) is 114 bytes (4 Longs + 3 Integers). This means that we need to take the collector max (1MB) and subtract our payload size to figure out how much data we can include before potentially going over the limit.

Constant Field Values

STACK_TRIM

public static final int STACK_TRIM

The amount to trim a stack size by if as long as its encoded size is greater than MAX_ENCODED_BYTES.
