-------------------------------
Summary: TBufferedTransport performance issue since 0.10.0
Key: THRIFT-4102
URL: https://issues.apache.org/jira/browse/THRIFT-4102
Project: Thrift
Issue Type: Bug
Components: Python - Library
Affects Versions: 0.10.0
Reporter: Jin Yao
I upgrade thrift from 0.9.3 to 0.10.0, and our rpc calls slow down.
I digged around the code, and find maybe it caused by the write function in
TBufferedTransport.
The last line seems useless, but cost time.
{code:title=TTransport.py|borderStyle=solid}
def write(self, buf):
try:
self.__wbuf.write(buf)
except Exception as e:
# on exception reset wbuf so it doesn't contain a partial function
call
self.__wbuf = BufferIO()
raise e
self.__wbuf.getvalue() # it seems useless, but cost time
{code}
