Delete all items in a dynamo db table

aws-dynamo-db-delete-all-items.zsh

#!/usr/bin/env zsh

# I'm using jq to parse json. I really suggest using it.
# I'm using parallel for faster results, you could use xargs or a for loop if you don't have parallel.

main() (
	set -eux
	local options="--profile some-profile"
	local key='id'
	local table='table'
	local keys_json=$(aws $options dynamodb scan --table-name $table --attributes-to-get $key | jq --compact-output '.Items[]')
	# Parallel uses "\n" as a delimiter. So as long as none of you strings contains a "\n", you'll be ok.
	[[ $#keys_json > 0 ]] && parallel "aws $options dynamodb delete-item --table-name $table --key" ::: "$keys_json"
)

main

just a small suggestion if you have more than one option

local options=(--region us-east-1 --profile some-profile)
[...]
local keys_json=$(aws "${options[@]}" dynamodb scan --table-name $table --attributes-to-get $key | jq --compact-output '.Items[]')

@raulvc it looks like cool but not necessary, could you tell me why you use that ? (my string already has a space in it and it is working quite well afaik!)

Thank you for sharing this script. Does it really delete all items, or just the first 1000 max (or 1MB worth of data)?

@ic I'm not sure woudl it would behave like you said ^^. It used to delete all, nowadays I don't know.
