Julian Reschke commented on OAK-3730:
-------------------------------------
[~mreutegg]: this is a somewhat hacky (*) approach to implement
{{VersionGCSupport.identifyGarbage}} which tries to only SQL-Select IDs that
can potentially be split documents:
{{noformat}}
List<String> keyPatterns = Arrays.asList(new String[] { "_:p%", "__:p%",
"___:p%", "____:p%", "_:h%", "__:h%", "___:h%", "___:h%" });
{{noformat}}
(I believe this includes all split docs and all longpath docs, thus resulting
in a new - harmless - false positives)
(*) as it depends on assumptions about ID pattern formats
> RDBDocumentStore: implement RDB-specific VersionGC support for lookup of
> split documents

> This requires a change to the table layout (adding SD_TYPE and more), thus
> needs thought about how to migrate from older versions of the persistence.
