---------------------------------
Summary: KnoxShellTable - Record the Creation Sequence of Tables
Key: KNOX-2023
URL: https://issues.apache.org/jira/browse/KNOX-2023
Project: Apache Knox
Issue Type: Improvement
Components: KnoxShell
Reporter: Larry McCay
Fix For: 1.4.0
Each KnoxShellTable instance goes through a number of builders, filters, sorts,
etc in order to get to their final state.
Currently, those builder classes just go out of scope as they complete and
return the resulting table.
This JIRA represents the thought of recording them in an ArrayList within the
table so that we could do a number of interesting things:
* persist JSON representation that doesn't require the actual data
* materialize tables from that persisted state by replaying the builders in
order
* possibly undo or rollback to a previous state
* possibly providing interesting provenance capabilities with confidence
factors based on sources
Interesting challenges here will be when authentication is required for a SQL
query in the JDBC builder or in accessing data accessed through Knox gateway
instances.
