// this nice note from @lemire on

// https://github.com/RoaringBitmap/roaring/pull/70#issuecomment-263613737
|
||||
//
|
||||
// Description of lazyOR and lazyIOR from @lemire:
|
||||
//
|
||||
// Lazy functions are optional and can be simply
|
||||
// wrapper around non-lazy functions.
|
||||
//
|
||||
// The idea of "laziness" is as follows. It is
|
||||
// inspired by the concept of lazy evaluation
|
||||
// you might be familiar with (functional programming
|
||||
// and all that). So a roaring bitmap is
|
||||
// such that all its containers are, in some
|
||||
// sense, chosen to use as little memory as
|
||||
// possible. This is nice. Also, all bitsets
|
||||
// are "cardinality aware" so that you can do
|
||||
// fast rank/select queries, or query the
|
||||
// cardinality of the whole bitmap... very fast,
|
||||
// without latency.
|
||||
//
|
||||
// However, imagine that you are aggregating 100
|
||||
// bitmaps together. So you OR the first two, then OR
|
||||
// that with the third one and so forth. Clearly,
|
||||
// intermediate bitmaps don't need to be as
|
||||
// compressed as possible, right? They can be
|
||||
// in a "dirty state". You only need the end
|
||||
// result to be in a nice state... which you
|
||||
// can achieve by calling repairAfterLazy at the end.
|
||||
//
|
||||
// The Java/C code does something special for
|
||||
// the in-place lazy OR runs. The idea is that
|
||||
// instead of taking two run containers and
|
||||
// generating a new one, we actually try to
|
||||
// do the computation in-place through a
|
||||
// technique invented by @gssiyankai (pinging him!).
|
||||
// What you do is you check whether the host
|
||||
// run container has lots of extra capacity.
|
||||
// If it does, you move its data at the end of
|
||||
// the backing array, and then you write
|
||||
// the answer at the beginning. What this
|
||||
// trick does is minimize memory allocations.

|
|||
|
||||
Strangely, though the streaming format was first proposed in Go[1][2], it was never upated, and I could not locate any other library for Go that would handle the streaming/framed snappy format. Hence this implementation of the spec. There is a command line tool[3] that has a C implementation, but this is the only Go implementation that I am aware of. The reference for the framing/streaming spec seems to be the python implementation[4].
|
||||
|
||||
For binary compatibility with the python implementation, one could use the C-snappy compressor/decompressor code directly; using github.com/dgryski/go-csnappy. In fact we did this for a while to verify byte-for-byte compatiblity, as the native Go implementation produces slightly different binary compression (still conformant with the standard of course), which made test-diffs harder, and some have complained about it being slower than the C.
|
||||
Update to the previous paragraph: Horray! Good news: Thanks to @nigeltao, we have since learned that the [github.com/golang/snappy](https://github.com/golang/snappy) package now provides the snappy streaming format too. Even though the type level descriptions are a little misleading because they don't mention that they are for the stream format, the [snappy package header documentation](https://godoc.org/github.com/golang/snappy) points out that the [snappy.Reader](https://godoc.org/github.com/golang/snappy#Reader) and [snappy.Writer](https://godoc.org/github.com/golang/snappy#Writer) types do indeed provide stream (vs block) handling. Although I have not benchmarked, you should probably prefer that package as it will likely be maintained more than I have time to devote, and also perhaps better integrated with the underlying snappy as they share the same repo.
|
||||
|
||||
For binary compatibility with the [python implementation](https://pypi.python.org/pypi/python-snappy) in [4], one could use the C-snappy compressor/decompressor code directly; using github.com/dgryski/go-csnappy. In fact we did this for a while to verify byte-for-byte compatiblity, as the native Go implementation produces slightly different binary compression (still conformant with the standard of course), which made test-diffs harder, and some have complained about it being slower than the C.
|
||||
|
||||
However, while the c-snappy was useful for checking compatibility, it introduced dependencies on external C libraries (both the c-snappy library and the C standard library). Our go binary executable that used the go-unsnap-stream library was no longer standalone, and deployment was painful if not impossible if the target had a different C standard library. So we've gone back to using the snappy-go implementation (entirely in Go) for ease of deployment. See the comments at the top of unsnap.go if you wish to use c-snappy instead.
