ReaderProviderHelper | |
SharedReaderProvider | Deprecated. replaced by SharingBufferReaderProvider |
SharingBufferReaderProvider | This ReaderProvider shares IndexReaders as long as they are "current";
main difference with SharedReaderProvider is the way to update the Readers when needed:
this uses IndexReader.reopen() which should improve performance on larger indexes
as it shares buffers with previous IndexReader generation for the segments which didn't change. |
