Re: [Discussion] Encryption support for carbondata files

[manish gupta <to...@gmail.com>]

Hi Ajantha

+1 for starting this discussion and +1 for the new feature. It is good to
have a feature like Encryption from security point of view.
During further analysis and design you can think on the following points.
1. Partial Encryption (column based encryption with configurable encryption
algorithms)
2. Complete file encryption
3. Different encryption algorithm for footer metadata and actual data.

Hi,ajantha
+1
this is good feature for some user.

we can support column level encryption.  because some users want to encrypt
some columns, not all, such as encrypt password column.
