Nayuta Yanagisawa 0f6e170c34 MDEV-25985 Spider handle ">=" as ">" in some cases 
The function spider_db_append_key_where_internal() converts
HA_READ_AFTER_KEY to '>'. The conversion seems to be correct for
single-column indexes because HA_READ_AFTER_KEY means "read the
key after the provided value."

However, how about multi-column indexes? Assume that there is a
multi-column index on c1 and c2 and we search with the condition
'c1 >= 100 AND c2 > 200'. The key_range.flag corresponds to the
search condition could be HA_READ_AFTER_KEY. In such a case,
we could not simply convert HA_READ_AFTER_KEY to '>'.

The correct conversion is to convert HA_READ_AFTER_KEY to '>'
only for the last column in key_part_map and to convert
HA_READ_AFTER_KEY to '>=' for the other column.

The similar discussion also applies to the conversion from
key_range.flag to a sign of inequality.
