      Description

      Hi,

      In my 10.5.16 (at the time it was maybe running 10.5.15) data directory I found some strange files:

      -rw-r----- 1 mysql mysql 67108864 Dec 21  2021 0x003d7642_data.000000
      -rw-r----- 1 mysql mysql 67108864 Dec 21  2021 0x003d7642_data.000001
      -rw-r----- 1 mysql mysql 67108864 Dec 21  2021 0x003d7642_data.000002
      -rw-r----- 1 mysql mysql 67108864 Dec 21  2021 0x003d7642_data.000003
      -rw-r----- 1 mysql mysql 67108864 Dec 24  2021 0x0096557b_data.000000
      -rw-r----- 1 mysql mysql 67108864 Dec 24  2021 0x009693e2_data.000000
      

      My guess is that this is coming from LOAD DATA splitting in Galera (which then crashed) but I am not sure as I cannot find anything about it in the documentation.

      Can you perhps elaborate what these files are? And, add it to the documentation

      Thank you,
      Michaël
