Maximum line length supported by logstash?

Question

What is the maximum character length does logstash can read as a single event from a file (single line input, NOT multiline input)? Also does logstash take specific number of spaces/tabs in between a line as newline?

Looks like the file input uses filewatch, which has a 32K limit.

The previous answer is referring to an old version of filewatch where the chunk size was hard-coded to 32K

Recent file-input still uses this as the default chunk size but allows configuration if the line is longer than 32K.

The plugin also prints a warning when a delimiter is not found reading a chunk.
