| benchmarks | ||
| ========== | ||
|
|
||
| This is a small module that pulls in a bunch of storage implementations, | ||
| as well as legacy implementations via the adapter modules, | ||
| and benchmarks all of them on the same benchmarks. | ||
|
|
||
| There's no reason to import this code, | ||
| so the go.mod file uses relative paths shamelessly. | ||
| (You can create your own benchmarks using the code in `../tests`, | ||
| which contains most of the engine; this package is just tables of setup.) | ||
|
|
||
|
|
||
| What variations do the benchmarks exercise? | ||
| ------------------------------------------ | ||
|
|
||
| - the various storage implementations! | ||
| - in some cases: variations of parameters to individual storage implementations. (TODO) | ||
| - puts and gets. (TODO: currently only puts.) | ||
| - various distributions of data size. (TODO) | ||
| - block mode vs streaming mode. (TODO) | ||
| - end-to-end use via linksystem with small cbor objects. (TODO) | ||
| - (this measures a lot of things that aren't to do with the storage itself -- but is useful to contextualize things.) | ||
|
|
||
| Running the benchmarks on variations in hardware and filesystem may also be important! | ||
| Many of these storage systems use the disk in some way. | ||
|
|
||
|
|
||
| Why is the module structured like this? | ||
| ---------------------------------------- | ||
|
|
||
| See similar discussion in the `../dsadapter` module. | ||
|
|
||
| Long story short: to keep legacy dependencies from appearing in modern dependency trees, | ||
| even though we want to test them, and want to do it without spawning yet more git repos. | ||
|
|
||
| It may be worth pulling this out into a new git repo in the future, | ||
| especially if we want to add more and more implementations to what we benchmark, | ||
| or develop additional tools for deploying the benchmark on varying hardware, etc. | ||
| For now, it incubates here. |

| bsadapter | ||
| ========= | ||
|
|
||
| The `bsadapter` package/module is a small piece of glue code to connect | ||
| the `github.com/ipfs/go-blockstore` package, and packages implementing its interfaces, | ||
| forward into the `go-ipld-prime/storage` interfaces. | ||
|
|
||
|
|
||
| Why structured like this? | ||
| ------------------------- | ||
|
|
||
| See similar discussion in the `../dsadapter` module. | ||
|
|
||
|
|
||
| Which of `dsadapter` vs `bsadapter` vs `bsrvadapter` should I use? | ||
| ------------------------------------------------------------------ | ||
|
|
||
| None of them, ideally. | ||
| A direct implementation of the storage APIs will almost certainly be able to perform better than any of these adapters. | ||
|
|
||
| Failing that: use the adapter matching whatever you've got on hand in your code. | ||
|
|
||
| There is no correct choice. | ||
|
|
||
| dsadapter suffers avoidable excessive allocs in processing its key type, | ||
| due to choices in the interior of `github.com/ipfs/go-datastore`. | ||
| It is also unable to support streaming operation, should you desire it. | ||
|
|
||
| bsadapter and bsrvadapter both also suffer overhead due to their key type, | ||
| because they require a transformation back from the plain binary strings used in the storage API to the concrete go-cid type, | ||
| which spends some avoidable CPU time (and also, at present, causes avoidable allocs because of some interesting absenses in `go-cid`). | ||
| Additionally, they suffer avoidable allocs because they wrap the raw binary data in a "block" type, | ||
| which is an interface, and thus heap-escapes; and we need none of that in the storage APIs, and just return the raw data. | ||
| They are also unable to support streaming operation, should you desire it. | ||
|
|
||
| It's best to choose the shortest path and use the adapter to whatever layer you need to get to -- | ||
| for example, if you really want to use a `go-datastore` implementation, | ||
| *don't* use `bsadapter` and have it wrap a `go-blockstore` that wraps a `go-datastore` if you can help it: | ||
| instead, use `dsadapter` and wrap the `go-datastore` without any extra layers of indirection. | ||
| You should prefer this because most of the notes above about avoidable allocs are true when | ||
| the legacy interfaces are communicating with each other, as well... | ||
| so the less you use the internal layering of the legacy interfaces, the better off you'll be. | ||
|
|
||
| Using a direct implementation of the storage APIs will suffer none of these overheads, | ||
| and so will always be your best bet if possible. | ||
|
|
||
| If you have to use one of these adapters, hopefully the performance overheads fall within an acceptable margin. | ||
| If not: we'll be overjoyed to accept help porting things. |
