+# BigCache [](https://travis-ci.org/allegro/bigcache) [](https://coveralls.io/github/allegro/bigcache?branch=master) [](https://godoc.org/github.com/allegro/bigcache) [](https://goreportcard.com/report/github.com/allegro/bigcache)
+
+Fast, concurrent, evicting in-memory cache written to keep big number of entries without impact on performance.
+BigCache keeps entries on heap but omits GC for them. To achieve that operations on bytes arrays take place,
+therefore entries (de)serialization in front of the cache will be needed in most use cases.
+
+## Usage
+
+### Simple initialization
+
+```go
+import "github.com/allegro/bigcache"
+
+cache, _ := bigcache.NewBigCache(bigcache.DefaultConfig(10 * time.Minute))
+
+cache.Set("my-unique-key", []byte("value"))
+
+entry, _ := cache.Get("my-unique-key")
+fmt.Println(string(entry))
+```
+
+### Custom initialization
+
+When cache load can be predicted in advance then it is better to use custom initialization because additional memory
+allocation can be avoided in that way.
+
+```go
+import (
+ "log"
+
+ "github.com/allegro/bigcache"
+)
+
+config := bigcache.Config {
+ // number of shards (must be a power of 2)
+ Shards: 1024,
+ // time after which entry can be evicted
+ LifeWindow: 10 * time.Minute,
+ // rps * lifeWindow, used only in initial memory allocation
+ MaxEntriesInWindow: 1000 * 10 * 60,
+ // max entry size in bytes, used only in initial memory allocation
+ MaxEntrySize: 500,
+ // prints information about additional memory allocation
+ Verbose: true,
+ // cache will not allocate more memory than this limit, value in MB
+ // if value is reached then the oldest entries can be overridden for the new ones
+ // 0 value means no size limit
+ HardMaxCacheSize: 8192,
+ // callback fired when the oldest entry is removed because of its expiration time or no space left
+ // for the new entry, or because delete was called. A bitmask representing the reason will be returned.
+ // Default value is nil which means no callback and it prevents from unwrapping the oldest entry.
+ OnRemove: nil,
+ // OnRemoveWithReason is a callback fired when the oldest entry is removed because of its expiration time or no space left
+ // for the new entry, or because delete was called. A constant representing the reason will be passed through.
+ // Default value is nil which means no callback and it prevents from unwrapping the oldest entry.
+ // Ignored if OnRemove is specified.
+ OnRemoveWithReason: nil,
+ }
+
+cache, initErr := bigcache.NewBigCache(config)
+if initErr != nil {
+ log.Fatal(initErr)
+}
+
+cache.Set("my-unique-key", []byte("value"))
+
+if entry, err := cache.Get("my-unique-key"); err == nil {
+ fmt.Println(string(entry))
+}
+```
+
+## Benchmarks
+
+Three caches were compared: bigcache, [freecache](https://github.com/coocood/freecache) and map.
+Benchmark tests were made using an i7-6700K with 32GB of RAM on Windows 10.
+
+### Writes and reads
+
+```bash
+cd caches_bench; go test -bench=. -benchtime=10s ./... -timeout 30m
+
+BenchmarkMapSet-8 3000000 569 ns/op 202 B/op 3 allocs/op
+BenchmarkConcurrentMapSet-8 1000000 1592 ns/op 347 B/op 8 allocs/op
+BenchmarkFreeCacheSet-8 3000000 775 ns/op 355 B/op 2 allocs/op

+BenchmarkConcurrentMapSetParallel-8 5000000 318 ns/op 200 B/op 6 allocs/op
+BenchmarkBigCacheGetParallel-8 20000000 178 ns/op 152 B/op 4 allocs/op
+BenchmarkFreeCacheGetParallel-8 20000000 295 ns/op 136 B/op 3 allocs/op
+BenchmarkConcurrentMapGetParallel-8 10000000 237 ns/op 24 B/op 2 allocs/op
+```
+
+Writes and reads in bigcache are faster than in freecache.
+Writes to map are the slowest.
+
+### GC pause time
+
+```bash
+cd caches_bench; go run caches_gc_overhead_comparison.go
+
+Number of entries: 20000000
+GC pause for bigcache: 5.8658ms
+GC pause for freecache: 32.4341ms
+GC pause for map: 52.9661ms
+```
+
+Test shows how long are the GC pauses for caches filled with 20mln of entries.
+Bigcache and freecache have very similar GC pause time.
+It is clear that both reduce GC overhead in contrast to map
+which GC pause time took more than 10 seconds.
+
+## How it works
+
+BigCache relies on optimization presented in 1.5 version of Go ([issue-9477](https://github.com/golang/go/issues/9477)).
+This optimization states that if map without pointers in keys and values is used then GC will omit its content.
+Therefore BigCache uses `map[uint64]uint32` where keys are hashed and values are offsets of entries.
+
+Entries are kept in bytes array, to omit GC again.
+Bytes array size can grow to gigabytes without impact on performance
+because GC will only see single pointer to it.
+
+## Bigcache vs Freecache
+
+Both caches provide the same core features but they reduce GC overhead in different ways.
+Bigcache relies on `map[uint64]uint32`, freecache implements its own mapping built on
+slices to reduce number of pointers.
+
+Results from benchmark tests are presented above.
+One of the advantage of bigcache over freecache is that you don’t need to know
+the size of the cache in advance, because when bigcache is full,
+it can allocate additional memory for new entries instead of
+overwriting existing ones as freecache does currently.
+However hard max size in bigcache also can be set, check [HardMaxCacheSize](https://godoc.org/github.com/allegro/bigcache#Config).
+
+## HTTP Server
+
+This package also includes an easily deployable HTTP implementation of BigCache, which can be found in the [server](/server) package.
