# xxhash
|
||||
|
||||
[](https://godoc.org/github.com/cespare/xxhash)
|
||||
|
||||
xxhash is a Go implementation of the 64-bit
|
||||
[xxHash](http://cyan4973.github.io/xxHash/) algorithm, XXH64. This is a
|
||||
high-quality hashing algorithm that is much faster than anything in the Go
|
||||
standard library.
|
||||
|
||||
The API is very small, taking its cue from the other hashing packages in the
|
||||
standard library:
|
||||
|
||||
$ go doc github.com/cespare/xxhash !
|
||||
package xxhash // import "github.com/cespare/xxhash"
|
||||
|
||||
Package xxhash implements the 64-bit variant of xxHash (XXH64) as described
|
||||
at http://cyan4973.github.io/xxHash/.
|
||||
|
||||
func New() hash.Hash64
|
||||
func Sum64(b []byte) uint64
|
||||
func Sum64String(s string) uint64
|
||||
|
||||
This implementation provides a fast pure-Go implementation and an even faster
|
||||
assembly implementation for amd64.
|
||||
|
||||
## Benchmarks
|
||||
|
||||
Here are some quick benchmarks comparing the pure-Go and assembly
|
||||
implementations of Sum64 against another popular Go XXH64 implementation,
|
||||
[github.com/OneOfOne/xxhash](https://github.com/OneOfOne/xxhash):
|
||||

||||

|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|

|
||||
of this License, Derivative Works shall not include works that remain

|
||||

||||
copyright license to reproduce, prepare Derivative Works of,

|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.

Blobloom
|
||||
========
|
||||
|
||||
A Bloom filter package for Go (golang) with no compile-time dependencies.
|
||||
|
||||
This package implements a version of Bloom filters called [blocked Bloom filters](
|
||||
https://algo2.iti.kit.edu/documents/cacheefficientbloomfilters-jea.pdf),
|
||||
which get a speed boost from using the CPU cache more efficiently
|
||||
than regular Bloom filters.
|
||||
|
||||
Unlike most Bloom filter packages for Go,
|
||||
this one doesn't run a hash function for you.
|
||||
That's a benefit if you need a custom hash
|
||||
or you want pick the fastest one for an application.
|
||||
|
||||
Usage
|
||||
-----
|
||||
|
||||
To construct a Bloom filter, you need to know how many keys you want to store
|
||||
and what rate of false positives you find acceptable.
|
||||
|
||||
f := blobloom.NewOptimized(blobloom.Config{
|
||||
Capacity: nkeys, // Expected number of keys.
|
||||
FPRate: 1e-4, // Accept one false positive per 10,000 lookups.
|
||||
})
|
||||
|
||||
To add a key:
|
||||
|
||||
// import "github.com/cespare/xxhash/v2"
|
||||
f.Add(xxhash.Sum64(key))
|
||||
|
||||
To test for the presence of a key in the filter:
|
||||
|
||||
if f.Has(xxhash.Sum64(key)) {
|
||||
// Key is probably in f.
|
||||
} else {
|
||||
// Key is certainly not in f.
|
||||
}
|
||||
|
||||
The false positive rate is defined as usual:
|
||||
if you look up 10,000 random keys in a Bloom filter filled to capacity,
|
||||
an expected one of those is a false positive for FPRate 1e-4.
|
||||
|
||||

|
||||

||||

||||
Hash functions
|
||||
--------------
|
||||
|
||||
Blobloom does not provide hash functions. Instead, it requires client code to
|
||||
represent each key as a single 64-bit hash value, leaving it to the user to
|
||||
pick the right hash function for a particular problem. Here are some general
|
||||
suggestions:
|
||||
|
||||
* If you use Bloom filters to speed up access to a key-value store, you might
|
||||
want to look at [xxh3](https://github.com/zeebo/xxh3) or [xxhash](
|
||||
https://github.com/cespare/xxhash).
|
||||
* If your keys are cryptographic hashes, consider using the first 8 bytes of those hashes.
|
||||
* If you use Bloom filters to make probabilistic decisions, a randomized hash
|
||||
function such as [maphash](https://golang.org/pkg/hash/maphash) should prevent
|
||||
the same false positives occurring every time.
|
||||
|
||||
When evaluating a hash function, or designing a custom one,
|
||||
make sure it is a 64-bit hash that properly mixes its input bits.
|
||||
Casting a 32-bit hash to uint64 gives suboptimal results.
|
||||
So does passing integer keys in without running them through a mixing function.

// Package blobloom implements blocked Bloom filters.
|
||||
//
|
||||
// Blocked Bloom filters are an approximate set data structure: if a key has
|
||||
// been added to a filter, a lookup of that key returns true, but if the key
|
||||
// has not been added, there is a non-zero probability that the lookup still
|
||||
// returns true (a false positive). False negatives are impossible: if the
|
||||
// lookup for a key returns false, that key has not been added.
|
||||
//
|
||||
// In this package, keys are represented exclusively as hashes. Client code
|
||||
// is responsible for supplying a 64-bit hash value.
|
||||
//
|
||||
// Compared to standard Bloom filters, blocked Bloom filters use the CPU
|
||||
// cache more efficiently. A blocked Bloom filter is an array of ordinary
|
||||
// Bloom filters of fixed size BlockBits (the blocks). The lower half of the
|
||||
// hash selects the block to use.
|
||||
//
|
||||
// To achieve the same false positive rate (FPR) as a standard Bloom filter,
|
||||
// a blocked Bloom filter requires more memory. For an FPR of at most 2e-6
|
||||
// (two in a million), it uses ~20% more memory. At 1e-10, the space required
|
||||
// is double that of standard Bloom filter.
|
||||
//

||||
// For more details, see the 2010 paper by Putze, Sanders and Singler,
