Stefan Egli created OAK-3001: -------------------------------- Summary: Simplify JournalGarbageCollector using a dedicated timestamp property Key: OAK-3001 URL: https://issues.apache.org/jira/browse/OAK-3001 Project: Jackrabbit Oak Issue Type: Sub-task Components: core, mongomk Reporter: Stefan Egli Priority: Critical Fix For: 1.3.1, 1.2.3
This subtask is about spawning out a [comment|https://issues.apache.org/jira/browse/OAK-2829?focusedCommentId=14585733&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14585733] from [~chetanm] re JournalGC: {quote} Further looking at JournalGarbageCollector ... it would be simpler if you record the journal entry timestamp as an attribute in JournalEntry document and then you can delete all the entries which are older than some time by a simple query. This would avoid fetching all the entries to be deleted on the Oak side {quote} and a corresponding [reply|https://issues.apache.org/jira/browse/OAK-2829?focusedCommentId=14585870&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14585870] from myself: {quote} Re querying by timestamp: that would indeed be simpler. With the current set of DocumentStore API however, I believe this is not possible. But: [DocumentStore.query|https://github.com/apache/jackrabbit-oak/blob/trunk/oak-core/src/main/java/org/apache/jackrabbit/oak/plugins/document/DocumentStore.java#L127] comes quite close: it would probably just require the opposite of that method too: {code} public <T extends Document> List<T> query(Collection<T> collection, String fromKey, String toKey, String indexedProperty, long endValue, int limit) { {code} .. or what about generalizing this method to have both a {{startValue}} and an {{endValue}} - with {{-1}} indicating when one of them is not used? {quote} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
