-----------------------------------
Summary: VersionGCSupport for RDB persistence
Key: OAK-2252
URL: https://issues.apache.org/jira/browse/OAK-2252
Project: Jackrabbit Oak
Issue Type: Sub-task
Components: rdbmk
Affects Versions: 1.1.1
Reporter: Julian Reschke
Priority: Minor
The DocumentMK's VersionGCSupport code currently special-cases the Mongo
persistence.
Needed are two optimized queries:
1) deletedOnce = true AND modifiedInSecs < lastModified
2) sdType in (....) AND sdMaxRevTimeInSecs < oldestRevTimeStamp
(where in the case of 2) the matching documents cam be removed right away)
TODO:
a) find out which of these system properties ought to be indexed properties
b) decide on whether we can implement this as generic interface extension of
DocumentStore, or whether we add custom code for the RDBDocumentStore similary
to what Mongo does
on b): I think we should aim for *removing* persistence-specific code from the
kernel, so we probably should add extension interfaces for these.
