Subject dot drill file
Date Mon, 02 Nov 2015 06:18:38 GMT
I'd like to capture the requirement for dot drill files.
Here is my understanding:
A ".drill" file is in JSON format and is a mechanism provided by the
FileSystemPlugin to define the format plugin to use collocated with the
files containing the data in a file system. It will override any extension
or magic number header mapping.
It will enable configuring the format plugin and record level error
handling mechanism (bad record skipping, etc). It could be extended to
support more in the future.
Is this correct? Are there inheritance rules if more than one file is found
in the hierarchy? Does drill look only at the dir containing the files or
also all parent directories?
