Yonik Seeley updated SOLR-2700: ------------------------------- Attachment: SOLR-2700.patch Here's a draft patch. There is a tlog.<number> file created for each commit. The javabin format is used to serialize SolrInputDocuments. An in-memory map of pointers into the log is kept for documents not yet soft-committed, and the realtime-get component checks that first before using SolrCore.getNewestSearcher(). Seems to work for getting documents not in the newest searcher so far. Tons of stuff left to do - the tlog files are currently in the CWD - need to handle deletes - need to handle flushes in a performant way - need to implement optional fsync for durability on power-failure - would be nice to make some of this multi-threaded for better performance - need to implement durability (apply updates from logs on startup) - need to implement some form of cleanup for transaction logs > transaction logging > ------------------- > > Key: SOLR-2700 > URL: https://issues.apache.org/jira/browse/SOLR-2700 > Project: Solr > Issue Type: New Feature > Reporter: Yonik Seeley > Attachments: SOLR-2700.patch > > > A transaction log is needed for durability of updates, for a more performant > realtime-get, and for replaying updates to recovering peers. -- This message is automatically generated by JIRA.
