Tornado: Event Loop Blocking And Excess Memory Use From Chunked Bodies With Many Small Chunks
Summary When Tornado reads an HTTP/1.1 body that uses chunked transfer encoding, it processes all chunks that have already arrived without yielding to the event loop. A client can send a body made of millions of 1-byte chunks, which blocks the event loop and therefore every other connection serve...
