LogFormat
A format should only return true
if it can,
at least in some situations, support this sort of parsing.
If a format requires reading the entire file, it
must return false
.
If a format is not splittable, a file in the format cannot be parsed in parallel; however, individual files can still be parsed independently in parallel, as when reading the contents of a directory or using a file globbing pattern.
