@daipom @ashie need some comments on this since its a very new compression method. I tried to make sure the existing support is not broken and added this feature additionally. Need to perform some more work but wanted to get some comments from you guys

daipom · 2024-10-04T01:30:20Z

Thanks! I will see this this weekend!

Athishpranav2003 · 2024-10-16T15:58:29Z

@daipom did u get chance to look at this?

daipom · 2024-10-17T07:50:20Z

Sorry, I haven't made time for this. 😢
I'll make time for it this week.

Athishpranav2003 · 2024-10-17T11:24:16Z

Its fine i guess,
Even i was very busy in last 2 weeks 👍

@Athishpranav2003
I'm sorry for my late response. 😢

I have confirmed the entire direction!
It's great! Thanks for starting this enhancement!

Sorry I haven't made time to see the detailed implementation, such as Compressable module,
but the overall design of Fluentd would be essential for us now.
So, now, I comment on the overall direction of further modification.

It looks basically good as in_forward support!
All that is left is to support Output/Buffer/Chunk logic for output plugins. (Currently, these logic assumes gzip only)
To do so, it would be a good idea to support out_forward first.

The core logic would be the following.

EventStream#to_compressed_msgpack_stream

           def to_compressed_msgpack_stream(time_int: false, packer: nil) 
        
             packed = to_msgpack_stream(time_int: time_int, packer: packer) 
        
             compress(packed) 
        
           end

               end 
        
             end

It is complicated, but the compression of Buffer and Chunk and the flush process of output plugins are closely related.
The following existing implementations may be helpful for how output plugins behaves:

@daipom thanks for the review.

Yah, this will kick a lot more changes in the overall events pipeline.
For now i have just added the compression support as a module in Compressible. And used this in in-forward. I will try to look at Buffer as well in meantime(might need more time since i got busy with a project). I guess maybe splitting it into multiple PRs will be easy since i can finish small chunks one by one(seperate functionality) and easy to review

Athishpranav2003 · 2024-10-23T11:55:49Z

@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

daipom · 2024-10-25T07:55:47Z

@Athishpranav2003

can you please check the change in the Compression module as well

Sure! I will review the Compressable module!

Once if we merge this we can proceed with the other development around this

To judge if we can merge this only with the support of the module and in_forward, we need to reach an agreement on updating Forward Protocol Specification.

It would be necessary to update CompressedPackedForward Mode.
By allowing zstd as the value for the key compressed, it would be possible to add Zstd support while keeping compatibility, but I'm not sure yet.

Athishpranav2003 · 2024-10-25T08:33:39Z

Sure @daipom

If it's needed then I can split the PR into 2 where this will only focus on zstd and other one for in-forward

Athishpranav2003 · 2024-10-29T15:38:19Z

@daipom how to proceed in this PR?

daipom · 2024-10-30T09:39:39Z

Sorry, please give me a few more days 😢

daipom

@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

@daipom i addressed your comments but couldnt test it locally due to some issue.
yajl-ruby is already installed in my system but some other issue

daipom

Did not this code work?

#4657 (comment)

lib/fluent/plugin/in_forward.rb

Athishpranav2003 · 2024-11-05T02:44:29Z

I guess there is a small careless
Problem is local testing is not working at all. Could help me with that later

I will check after 18th
Got packed with exams now :(

Hmm, these changes would be necessary, but looks like the error in your environment is caused by another reason.

@daipom some doubts here

in chuck open method for decompress we dont have any type identification.
how to identify the chunk type while open/read method is called

fluentd/lib/fluent/plugin/buffer/chunk.rb

Lines 201 to 226 in 78a7972

    
           def open(**kwargs, &block) 
        
             if kwargs[:compressed] == :gzip

             else 
        
               super(**kwargs) do |chunk_io|

end

end

end

def read(**kwargs)

else

decompress(super)

end

end

I see!
The current implementation is based on the following assumption.

It is a gzip format chunk = It extends Decompressable module

fluentd/lib/fluent/plugin/buffer/chunk.rb

Lines 51 to 64 in 10f0f11

    
           def initialize(metadata, compress: :text) 
        
             super() 
        
             @unique_id = generate_unique_id 
        
             @metadata = metadata 
        
             # state: unstaged/staged/queued/closed 
        
             @state = :unstaged 
        
             @size = 0 
        
             @created_at = Fluent::Clock.real_now 
        
             @modified_at = Fluent::Clock.real_now 
        
             extend Decompressable if compress == :gzip 
        
           end

If we add a compression format, we need to change something here.
I discussed the direction with @Watson1978 and @kenhys.
We believe the following direction seems to be a good one.

Create Decompressable module for each compression format
- GzipDecompressable (Rename the current Decompressable)
- ZstdDecompressable
Switch modules to extend according to the compression format of the chunk

The current implementation of Decompressable looks a little weird to me.
I don't see the point of specifying the format in argument compressed
I don't want to change the signature for compatibility, but I believe a parameter like raw would be more correct...

Anyway, we only need to consider the possibility that gzip is specified for compressed for GzipDecompressable, and zstd for ZstdDecompressable.
(If a different compression format is specified to compressed, the chunk should ignore it and decompress itself.)

Athishpranav2003 · 2024-11-20T04:29:42Z

Oh ok
Let me again go through and check it

But what is that parameter compress referring to?
