System versioning doesn't support correct work for engine=connect and doesn't always give any warnings/errors

Details

    Description

      If add for engine=connect "system versioning" there is no any warnings/errors on creating table and inserting data, but "select" gives an empty result, "update" doesn't change value and "delete" fails with error:

      Test:

      create table t2 (
      		 
        x int,
      		 
        y int
      		 
      ) engine=connect table_type=FIX file_name='test.txt' with system versioning;
      		 
       
      		 
      insert into t2 values (1,1),(2,2),(3,3),(4,4),(5,5);
      		 
      select * from t2;
      		 
       
      		 
      update t2 set x=10 where y=4;
      		 
      select * from t2;
      		 
      delete from t2 where x=1;
      		 
      select * from t2;
      		 
       
      		 
      drop table t2;

      Result:

      create table t2 (
      		 
      x int,
      		 
      y int

      insert into t2 values (1,1),(2,2),(3,3),(4,4),(5,5);

      select * from t2;
      		 
      x	y
      		 
      delete from t2 where x=1;
