swiss.Map is a Go implementation of Google's Swiss Tables hash table
design. The Rust version of
Swiss Tables is now the HashMap
implementation in the Rust standard library.
A swiss.Map[K,V] maps keys of type K to values of type V, similar to
Go's builtin map[K]V type. The primary advantage of swiss.Map over Go's
builtin map is performance. swiss.Map has similar or slightly better
performance than Go's builtin map for small map sizes, and significantly
better performance at large map sizes. The benchmarks where swiss.Map
performs worse are due to a fast-path optimization in Go's builtin maps for
tiny (6 or fewer element) maps with int32, int64, or string keys, and when
growing a tiny map no initial capacity specified. In the latter case, Go's
builtin map is sometimes able to place the map and first bucket on the stack
avoiding heap allocations entirely.
Performance: Go's builtin map (old) vs swiss.Map (new)
Tested on a GCE n1-standard-16 instance.

On top of the base Swiss Tables design, swiss.Map adds an extendible
hashing layer in order to
enable incremental resizing of large maps which significantly reduces tail
latency for Put operations in maps with hundreds of thousands of entries or
more.
swiss.Map provides pseudo-randomized iteration (iteration order will change
from one iteration to the next) and iteration stability akin to Go's builtin
map if the map is mutated during iteration.
- The implementation currently requires a little endian CPU architecture. This is not a fundamental limitation of the implementation, merely a choice of expediency.
- Go's builtin map has a fast-path for comparing strings that share their
underlying
storage.
This fast-path is feasible because
map[string]Tis specialized for string keys which isn't currently possible with Go's generics. - Go's builtin map has a fast-path for maps with int32, int64, and string keys
that fit in a single bucket (8 entries) which avoids performing
hash(key)and simply linearly searches through the bucket. Similar to the above, this fast-path is feasible because the runtime can specialize the implementation on the key type.
- Add support for SIMD searching on x86 and 8-byte Neon SIMD searching on
arm64
- This appears to be somewhat difficult. Naively implementing the match routines in assembly isn't workable as the function call overhead dominates the performance improvement from the SIMD comparisons. The Abseil implementation is leveraring gcc/llvm assembly intrinsics which are not currently available in Go. In order to take advantage of SIMD we'll have to write most/all of the probing loop in assembly.
