How to control the upload file's size in S3

[grontorino]

I'm confused how to set the Chunk_size to control the upload file size, it's seems not work after modify INPUT or SERVICE.
No matter how I modify the Buffer_Size or Buffer_Chunk_Size, the uploaded file size is still about 540Kb. Is there any other way？

Here is my config:

[SERVICE]
    Flush        300
    Daemon       Off
    Log_Level    warning
    HTTP_Server  On
    HTTP_Listen  0.0.0.0
    HTTP_Port    2020

    #log_Level                 info
    #storage.path              /var/log/
    #storage.sync              normal
    #storage.checksum          off
    #storage.backlog.mem_limit 200M

[INPUT]
    Name forward
    Host 0.0.0.0
    #storage.type  filesystem
    Buffer_Size 200M
    Buffer_Chunk_Size  10M

For golang plugin, there is no way to control emitting size. Could you send your feature request to fluent-bit-go repository?
