Simon Willnauer updated LUCENE-3218: ------------------------------------ Attachment: LUCENE-3218.patch final patch. * fixed javadocs + several javadoc warnings * renamed openCompoundOutput to createCompoundOutput * fixed file extensions in test CSF LOL!! * copyFileEntry now deletes files that are separately written once copied into the CFS. * converted asserts to exceptions in CFW I plan to commit this today if nobody objects. > Make CFS appendable > --------------------- > > Key: LUCENE-3218 > URL: https://issues.apache.org/jira/browse/LUCENE-3218 > Project: Lucene - Java > Issue Type: Improvement > Components: core/index > Affects Versions: 4.0 > Reporter: Simon Willnauer > Assignee: Simon Willnauer > Fix For: 4.0 > > Attachments: LUCENE-3218.patch, LUCENE-3218.patch, LUCENE-3218.patch, > LUCENE-3218.patch > > > Currently CFS is created once all files are written during a flush / merge. > Once on disk the files are copied into the CFS format which is basically a > unnecessary for some of the files. We can at any time write at least one file > directly into the CFS which can save a reasonable amount of IO. For instance > stored fields could be written directly during indexing and during a Codec > Flush one of the written files can be appended directly. This optimization is > a nice sideeffect for lucene indexing itself but more important for DocValues > and LUCENE-3216 we could transparently pack per field files into a single > file only for docvalues without changing any code once LUCENE-3216 is > resolved. -- This message is automatically generated by JIRA.
