Let's sync up on tomorrow's weekly hangout. Let me know if that does not work for you. > Refactor e/pstore interfaces and their factories to provide a unified > mechanism to access stores > ------------------------------------------------------------------------------------------------ > > Key: DRILL-4275 > URL: https://issues.apache.org/jira/browse/DRILL-4275 > Project: Apache Drill > Issue Type: Improvement > Components: Execution - Flow > Reporter: Hanifi Gunes > Assignee: Deneche A. Hakim > > We rely on E/PStore interfaces to persist data. Even though E/PStore stands > for Ephemeral and Persistent stores respectively, the current design for > EStore does not extend the interface/functionality of PStore at all, which > hints abstraction for EStore is redundant. This issue proposes a new unified > Store interface replacing the old E/PStore that exposes an additional method > that report persistence level as follows: > {code:title=Store interface} > interface Store<V> { > StoreMode getMode(); > V get(String key); > ... > } > enum StoreMode { > EPHEMERAL, > PERSISTENT, > ... > } > {code} > The new design brings in less redundancy, more centralized code, ease to > reason and maintain. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
