Research direction
Start by reproducing the error on Red Hat Enterprise Linux 8.4 with the TiFlash 6.1 image described in the report, using the DTFile path shown in the exception. Trace the DTFile read and compression handling for method 200, then establish why profiling produces the invalid method and verify that the query completes without the exchange or compression error.
