Simon Willnauer updated LUCENE-2453: ------------------------------------ Attachment: LUCENE-2453.patch bringing this up-to-date.... I think this is pretty useful for downstream apps though. I plan to commit this soon too. > Make Index Output Buffer Size Configurable > ------------------------------------------ > > Key: LUCENE-2453 > URL: https://issues.apache.org/jira/browse/LUCENE-2453 > Project: Lucene - Core > Issue Type: Improvement > Components: core/store > Affects Versions: 4.0, 4.1 > Reporter: Karthick Sankarachary > Assignee: Simon Willnauer > Fix For: 4.2, 5.0 > > Attachments: LUCENE-2453.patch, LUCENE-2453.patch > > > Currently, the buffered index input class allows sub-classes and users > thereof to specify a size for the input buffer, which by default is 1024 > bytes. In practice, this option is leveraged by the simple file and compound > segment index input sub-classes. > By the same token, it would be nice if the buffered index output class could > open up it's buffer size for users to configure. In particular, this would > allow sub-classes thereof to align the output buffer size, which by default > is 16348 bytes, to that of the underlying directory's data unit. For example, > a network-based directory might want to buffer data in multiples of it's > maximum transmission unit. To use an existing use-case, the file system-based > directory could potentially choose to align it's output buffer size to the > operating system's file block size. > The proposed change to the buffered index output class involves defining a > one-arg constructor that takes a user-defined buffer size, and a default > constructor that uses the currently defined buffer size. -- This message is automatically generated by JIRA.
