You could read a logfmt file, even when the keys differ between entries, with:

```{r logfmt-example-import}
log.as.df <- lapply(readLines("file_in_logfmt.log"), function(x){
scan(textConnection(x), what = "raw", sep = " ", quote = "\"", quiet = TRUE)
}) |>
lapply(X=_, function(y){
key <- sub("(^[^=]*)=.*", "\\1", y)
value <- sub("^[^=]*=(.*)", "\\1", y)
names(value) <- key
return(value)
}) |>
lapply(X = _, as.data.frame.list) |>
dplyr::bind_rows(x = _) |>
# plyr::colwise(.fun = type.convert, x= _) |>
type.convert(x= _, as.is = TRUE, numerals = "no.loss", tryLogical = FALSE)
```
