Thanks! I will see this this weekend! |
|
@daipom did u get chance to look at this? |
|
Sorry, I haven't made time for this. 😢 |
|
Its fine i guess, |
|
@Athishpranav2003 I have confirmed the entire direction! Sorry I haven't made time to see the detailed implementation, such as It looks basically good as The core logic would be the following.
It is complicated, but the compression of Buffer and Chunk and the flush process of output plugins are closely related.

@daipom thanks for the review. Yah, this will kick a lot more changes in the overall events pipeline. |
|
@daipom can you please check the change in the Compression module as well. Once if we merge this we can proceed with the other development around this |
Sure! I will review the
To judge if we can merge this only with the support of the module and It would be necessary to update |
|
Sure @daipom If it's needed then I can split the PR into 2 where this will only focus on |
|
@daipom how to proceed in this PR? |

Sorry, please give me a few more days 😢 |

@Athishpranav2003
Sorry for my late response 😢
I have commented on some points, but basically it looks good! Thanks!
About our future policies, I think it is better not to separate the PRs, as these changes need to be considered in combination with updating Forward-Protocol.
How about supporting the out_forward by implementing Output/Buffer/Chunk logic in this PR?
My concern is whether we can support Buffer/Chunk zstd compression.
To support it, the compressed data must be able to be concatenated.
gzip allows it.
It appears that we can concat zstd files without any problems, but I wonder if this is an officially supported specification of zstd and zstd-ruby gem.
$ echo "Hello world" > 1
$ echo "Hello Fluentd" > 2
$ zstd -f 1
$ zstd -f 2
$ cat 1.zst 2.zst > 3.zst
$ zstd -d 3.zst
$ cat 3
Hello world
Hello Fluentd

How about splitting the logic for simplicity?

string_decompress_gzip(compressed_data)
