[jira] [Updated] (PARQUET-1325) Flexible and finer-grained column
level access control through encryption
[ https://issues.apache.org/jira/browse/PARQUET-1325?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Xinli Shang updated PARQUET-1325:
---------------------------------
Description:
This JIRA is an extension to Modular Encryption Jira(PARQUET-1178) that will provide basic encryption support. This feature will enable finer-grained and flexible column level access control. Specifically, this will primarily allow a) individual encryption key for each column b) pluggable key access module c) seamless integration with existing clients.
A detailed design doc will follow soon.
was:
PARQUET-1178 proposed a mechanism for modular encryption and decryption of Parquet files. On top of it, another layer needs to be added to wrap up the details of the usage of encryption/decryption to shield upper layer application like Spark, Presto, Hive transparent.
The goal is no changes in the existing systems (i.e. Hive, Presto, Spark etc)
* Only update the parquet library and config
* Parquet schema should control the access
The code could be like below.
*ParquetWriter* (..., schema, ….) {
if(schema.hasCryptoColumn() && keys == null)
{ Keys = PluggableKeyManagement.getKeys(schema) }
……….
}
