Utility function to remove 'type' from bulk load files

Types are being removed from Elasticsearch. This little function aims to help remove "_type" fields from bulk newline-delimited JSON files. See Details.

Usage

type_remover(file)

Arguments

file

(character) a file path, required

Value

a file path for a temporary file with the types removed

Details

Looks for any lines that have an "index" key, then drops any "_type" keys in the hash given by the "index" key.

You can of course manually modify these files as an alternative, in a text editor or with command line tools like sed, etc.

Examples

if (FALSE) { # \dontrun{
z <- system.file("examples/omdb.json", package = "elastic")
readLines(z, 6)
ff <- type_remover(z)
readLines(ff, 6)
unlink(ff)
} # }
