Indexing Encrypted data

[thanigaiv]

I have some data that is written to C* as encrypted data (client side encryption). Is it possible to decrypt the data before indexing it?

Hi @thanigaiv,

It is not currently possible, but it probably could be done with a custom mapper designed for this purpose. Are you encrypting each cell value?

[thanigaiv]

Thanks. I have selected fields that are encrypted. Could you point me to the source where the mapper would be invoked?

Mappers are here. The idea is that you can modify one of the existing mappers or maybe create an new SingleColumnMapper and decrypt your data in the method addIndexedFields before indexing them.

@adelapena can you please provide example how to register that mapper to be recognized by the plugin?

@adelapena: Hi, I'm trying to define an index for filtering file paths (& a value that's assigned to it) with or without wildcards. Here's the index I created: CREATE CUSTOM INDEX search_idx ON db_3.my_files () USING 'com.stratio.cassandra.lucene.Index' WITH OPTIONS = {'refresh_seconds': '30', 'schema': '{fields: {path: {type: "text"},value: {type: "text"}}}'};

WDYT? Is there a better way to index a file path?
