in_s3: enable multiline parsing #429
Description
Is your feature request related to a problem? Please describe.
I noticed me and many users are wondering to be able to recognize logs that are on many lines.
Currently any plugin seemes to satisfy the thing, because:
- the fluentd multiline parsers applys on in_tail input only
- the fluent-plugin-concat plugin works only if the numeber of lines is well defined
Describe the solution you'd like
I propose to embed the multiline parser in the fluent-plugin-s3 as it works for in_tail input
Describe alternatives you've considered
I tried the flluent-plugin-concat plugin, but it ignore the multiline_start_regexp if it is not specified a fixed number of lines
I tried also applying the multiline parser with S3 source, but I got error
