Gidon Gershinsky commented on PARQUET-1178: ------------------------------------------- hard to say what's best at this point. Here's the arrow/parquet-cpp encryption [sample|[https://github.com/apache/arrow/blob/apache-arrow-0.16.0/cpp/examples/parquet/low-level-api/encryption-reader-writer-all-crypto-options.cc]]. > Parquet modular encryption > -------------------------- > > Key: PARQUET-1178 > URL: https://issues.apache.org/jira/browse/PARQUET-1178 > Project: Parquet > Issue Type: New Feature > Reporter: Gidon Gershinsky > Assignee: Gidon Gershinsky > Priority: Major > > A mechanism for modular encryption and decryption of Parquet files. Allows to > keep data fully encrypted in the storage - while enabling efficient analytics > on the data, via reader-side extraction / authentication / decryption of data > subsets required by columnar projection and predicate push-down. > Enables fine-grained access control to column data by encrypting different > columns with different keys. > Supports a number of encryption algorithms, to account for different security > and performance requirements. -- This message was sent by Atlassian Jira (v8.3.4#803005)
