Gidon Gershinsky updated PARQUET-1178:
--------------------------------------
Description:
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.
was:
A mechanism for modular encryption and decryption of Parquet files. Allows to
keep the data fully encrypted in the storage, while enabling a client to
extract a required subset (footer, column(s), pages) and to authenticate /
decrypt the extracted data.
