Lucene and Backing up the index : Since we're on the concurrency issue, can I take a back up from lucene while it's indexing or optimizing (using the writer), will this be a consistent backup image

Since the reader will be using the current index and the optimizer will be creating a new index there should be no problem. However, you will have to close the reader and reopen it to have it use the new index. There has been some mention on the list about the optimizer deleting the old indexes, but if you are using a unix machine then the index files will still be available as long as one process is using them. I don't know how this would work on Windows (my guess is it wouldn't be able to delete the index files in use). At least this is my understanding. --Peter On 6/2/02 10:54 PM, "V S" <[EMAIL PROTECTED]> wrote: > As optimization is a slightly different process, > basically merging segments, I was not sure if this > would not block, especially if you are querying on the > segment that is being merged? > > I do see indexing and searching working in parallel -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]> -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
