| Summary : Treat multiple files as one large seamless file for reading
|
Description :
This module provides a single-filehandle interface to multiple files, in
much the same way that a linear RAID provides a single-device interface to
multiple physical hard drives.
This module was written to provide random fixed-width record access to a
series of files. For example, in the BitTorrent filesharing protocol,
several files are shared as a single entity. The final sizes of the
individual files are known, but the protocol only sends fixed-width chunks
of data. These chunks are not aligned to file boundaries and can span
several physical files, but they are only identified by their overall
offset and not by the files they span.
This module was created to provide a layer of abstraction around this kind
of storage. Instead of calculating possibly many file offsets, and dividing
data into smaller pieces, a simple seek and read (or print) on the abstract
filehandle will do the right thing, regardless of how the chunk spans the
physical files:
seek $fh, ($chunk_id * $chunk_size), 0;
read $fh, my $buffer, $chunk_size;
seek $fh, ($chunk_id * $chunk_size), 0;
print $fh $chunk;
This module may prove useful if your physical file system has a low (2G)
limit on file sizes, yet you require access and storage for a large amount
of data through a single filehandle.
