receive()数据接收是否有长度限制

[yangex]

当数据长度比较长时，数据只能获取前面一部分，这个有哪里需要设置吗
class Converse:
"""Responsible for communication
between client and server
"""
def init(self, reader: object, writer: object, maxsize: int = 2**16):
self.reader = reader
self.writer = writer
self.message_queue = Queue(maxsize=maxsize)
self.frame = Frames(self.reader, self.writer)
看到您写的这个maxsize是用来限制数据长度的对吗，为什么加这样的限制呢？
