Examples of SegmentedFile

org.apache.cassandra.io.util.SegmentedFile
Abstracts a read-only file that has been split into segments, each of which can be represented by an independent FileDataInput. Allows for iteration over the FileDataInputs, or random access to the FileDataInput for a given position. The JVM can only map up to 2GB at a time, so each segment is at most that size when using mmap i/o. If a segment would need to be longer than 2GB, that segment will not be mmap'd, and a new RandomAccessFile will be created for each access to that segment.

        // remove the 'tmp' marker from all components
        final Descriptor newdesc = rename(descriptor, components);


        // finalize in-memory state for the reader
        SegmentedFile ifile = iwriter.builder.complete(newdesc.filenameFor(SSTable.COMPONENT_INDEX));
        SegmentedFile dfile = dbuilder.complete(newdesc.filenameFor(SSTable.COMPONENT_DATA));
        SSTableReader sstable = SSTableReader.internalOpen(newdesc, components, metadata, replayPosition, partitioner, ifile, dfile, iwriter.summary, iwriter.bf, maxDataAge, estimatedRowSize, estimatedColumnCount);
        iwriter = null;
        dbuilder = null;
