# gRPC (Core) Compression Cookbook |
||||
|
||||
## Introduction |
||||
|
||||
This document describes compression as implemented by the gRPC C core. See [the |
||||
full compression specification](compression.md) for details. |
||||
|
||||
### Intended Audience |
||||
|
||||
Wrapped languages developers, for the purposes of supporting compression by |
||||
interacting with the C core. |
||||
|
||||
## Criteria for GA readiness |
||||
|
||||
1. Be able to set compression at [channel](#per-channel-settings), |
||||
[call](#per-call-settings) and [message](#per-message-settings) level. |
||||
In principle this API should be based on _compression levels_ as opposed to |
||||
algorithms. See the discussion [below](#level-vs-algorithms). |
||||
1. Have unit tests covering [the cases from the |
||||
spec](https://github.com/grpc/grpc/blob/master/doc/compression.md#test-cases). |
||||
1. Interop tests implemented and passing on Jenkins. The two relevant interop |
||||
test cases are |
||||
[large_compressed_unary](https://github.com/grpc/grpc/blob/master/doc/interop-test-descriptions.md#large_compressed_unary) |
||||
and |
||||
[server_compressed_streaming](https://github.com/grpc/grpc/blob/master/doc/interop-test-descriptions.md#server_compressed_streaming). |
||||
|
||||
## Summary Flowcharts |
||||
|
||||
The following flowcharts depict the evolution of a message, both _incoming_ and |
||||
_outgoing_, irrespective of the client/server character of the call. Aspects |
||||
still not symmetric between clients and servers (e.g. the [use of compression |
||||
levels](https://github.com/grpc/grpc/blob/master/doc/compression.md#compression-levels-and-algorithms)) |
||||
are explicitly marked. The in-detail textual description for the different |
||||
scenarios is described in subsequent sections. |
||||
|
||||
## Incoming Messages |
||||
|
||||
 |
||||
|
||||
## Outgoing Messages |
||||
|
||||
 |
||||
|
||||
## Levels vs Algorithms |
||||
|
||||
As mentioned in [the relevant discussion on the spec |
||||
document](https://github.com/grpc/grpc/blob/master/doc/compression.md#compression-levels-and-algorithms), |
||||
compression _levels_ are the primary mechanism for compression selection _at the |
||||
server side_. In the future, it'll also be at the client side. The use of levels |
||||
abstracts away the intricacies of selecting a concrete algorithm supported by a |
||||
peer, on top of removing the burden of choice from the developer. |
||||
As of this writing (Q2 2016), clients can only specify compression _algorithms_. |
||||
Clients will support levels as soon as an automatic retry/negotiation mechanism |
||||
is in place. |
||||
|
||||
## Per Channel Settings |
||||
|
||||
Compression may be configured at channel creation. This is a convenience to |
||||
avoid having to repeatedly configure compression for every call. Note that any |
||||
compression setting on individual [calls](#per-call-settings) or |
||||
[messages](#per-message-settings) overrides channel settings. |
||||
|
||||
The following aspects can be configured at channel-creation time via channel arguments: |
||||
|
||||
#### Disable Compression _Algorithms_ |
||||
|
||||
Use the channel argument key |
||||
`GRPC_COMPRESSION_CHANNEL_ENABLED_ALGORITHMS_BITSET` (from |
||||
[`grpc/impl/codegen/compression_types.h`](https://github.com/grpc/grpc/blob/master/include/grpc/impl/codegen/compression_types.h)), |
||||
takes a 32 bit bitset value. A set bit means the algorithm with that enum value |
||||
according to `grpc_compression_algorithm` is _enabled_. |
||||
For example, `GRPC_COMPRESS_GZIP` currently has a numeric value of 2. To |
||||
enable/disable GZIP for a channel, one would set/clear the 3rd LSB (eg, 0b100 = |
||||
0x4). Note that setting/clearing 0th position, that corresponding to |
||||
`GRPC_COMPRESS_NONE`, has no effect, as no-compression (a.k.a. _identity_) is |
||||
always supported. |
||||
Incoming messages compressed (ie, encoded) with a disabled algorithm will result |
||||
in the call being closed with `GRPC_STATUS_UNIMPLEMENTED`. |
||||
|
||||
#### Default Compression _Level_ |
||||
|
||||
**(currently, Q2 2016, only applicable for server side channels. It's ignored |
||||
for clients.)** |
||||
Use the channel argument key `GRPC_COMPRESSION_CHANNEL_DEFAULT_LEVEL` (from |
||||
[`grpc/impl/codegen/compression_types.h`](https://github.com/grpc/grpc/blob/master/include/grpc/impl/codegen/compression_types.h)), |
||||
valued by an integer corresponding to a value from the `grpc_compression_level` |
||||
enum. |
||||
|
||||
#### Default Compression _Algorithm_ |
||||
|
||||
Use the channel argument key `GRPC_COMPRESSION_CHANNEL_DEFAULT_ALGORITHM` (from |
||||
[`grpc/impl/codegen/compression_types.h`](https://github.com/grpc/grpc/blob/master/include/grpc/impl/codegen/compression_types.h)), |
||||
valued by an integer corresponding to a value from the `grpc_compression_level` |
||||
enum. |
||||
|
||||
## Per Call Settings |
||||
|
||||
### Compression **Level** in Call Responses |
||||
|
||||
The server requests a compression level via initial metadata. The |
||||
`send_initial_metadata` `grpc_op` contains a `maybe_compression_level` field |
||||
with two fields, `is_set` and `compression_level`. The former must be set when |
||||
actively choosing a level to disambiguate the default value of zero (no |
||||
compression) from the proactive selection of no compression. |
||||
|
||||
The core will receive the request for the compression level and automatically |
||||
choose a compression algorithm based on its knowledge about the peer |
||||
(communicated by the client via the `grpc-accept-encoding` header. Note that the |
||||
absence of this header means no compression is supported by the client/peer). |
||||
|
||||
### Compression **Algorithm** in Call Responses |
||||
|
||||
**Server should avoid setting the compression algorithm directly**. Prefer |
||||
setting compression levels unless there's a _very_ compelling reason to choose |
||||
specific algorithms (benchmarking, testing). |
||||
|
||||
Selection of concrete compression algorithms is performed by adding a |
||||
`(GRPC_COMPRESS_REQUEST_ALGORITHM_KEY, <algorithm-name>)` key-value pair to the |
||||
initial metadata, where `GRPC_COMPRESS_REQUEST_ALGORITHM_KEY` is defined in |
||||
[`grpc/impl/codegen/compression_types.h`](https://github.com/grpc/grpc/blob/master/include/grpc/impl/codegen/compression_types.h)), |
||||
and `<algorithm-name>` is the human readable name of the algorithm as given in |
||||
[the HTTP2 spec](https://github.com/grpc/grpc/blob/master/doc/PROTOCOL-HTTP2.md) |
||||
for `Message-Encoding` (e.g. gzip, identity, etc.). See |
||||
[`grpc_compression_algorithm_name`](https://github.com/grpc/grpc/blob/master/src/core/lib/compression/compression.c) |
||||
for the mapping between the `grpc_compression_algorithm` enum values and their |
||||
textual representation. |
||||
|
||||
## Per Message Settings |
||||
|
||||
To disable compression for a specific message, the `flags` field of `grpc_op` |
||||
instances of type `GRPC_OP_SEND_MESSAGE` must have its `GRPC_WRITE_NO_COMPRESS` |
||||
bit set. Refer to |
||||
[`grpc/impl/codegen/compression_types.h`](https://github.com/grpc/grpc/blob/master/include/grpc/impl/codegen/compression_types.h)), |
