ndjson (version 0.8.0)

stream_in: Stream in & flatten an ndjson file into a data.table

Description

Given a file of streaming JSON (ndjson) this function reads in the records and creates a flat data.table / tbl from it.

Usage

stream_in(path, cls = c("dt", "tbl"))

Arguments

path

path to file (supports "gz" files)

cls

the package uses data.table::rbindlist for speed but that's not always the best return type for everyone, so you have option of keeping it a data.table or converting it to a tbl

Value

data.table or tbl
