How to fast parse a list of JSON string?

문제

I used rjson and do this JSON <- lapply(data$toParse, fromJSON)

my toParse has 600k rows of simple/short JSON.

However, it is very slow possibly because fromJSON doesn't vectorize operation so I have to use lapply.

I am wondering if there is any better way for parsing a list of JSON?

해결책

What about pasting the text into an array and parsing, rjson::fromJSON(sprintf("[%s]", paste(data$toParse, collapse=",")))?
