Go Report Card

A sql like command line prompt for AWS DynamoDB


Here is the situation, someone, likely your pm, tells you to find some user with a name like James Bond.

You fogot pin that aws console to chrome, and you just can’t remember how to use that crapy aws cli.


So skip the crap, just use dynamo.cli, the only thing you ever need to know is SQL.

Screenshot

NAME:
   dynamo.cli - DynamoDB command line prompt

USAGE:
   dynamo.cli [global options] command [command options] [arguments...]

VERSION:
   0.0.0

COMMANDS:
     help, h  Shows a list of commands or help for one command

GLOBAL OPTIONS:
   --key value, -k value          specify aws config access key id
   --secret value, -s value       specify aws config secret access key
   --region value, -r value       specify aws config region
   --tablePrefix value, -p value  specify certain prefix string for table names auto completion
   --help, -h                     show help (default: false)
   --version, -v                  print the version (default: false)

Install

Install from go get

go get github.com/FrontMage/dynamo.cli

Install from source

Note this method requires dep command installed.

git clone git@github.com:FrontMage/dynamo.cli.git $GOPATH/src/dynamo.cli

cd $GOPATH/src/dynamo.cli

dep ensure

go install

And you need awscli installed and configured, even after I passed this keys to the aws-go-sdk, you still need that…

If any one knows a way to skip this, please do share.

Install by download release binary

Checkout the latest released binary here .

Please do make an alias, otherwise you need specify your credentials everytime you do this.

alias dmcli="dynamo.cli -k yourKeyId -s yourSecretKey -r yourRegion"


SELECT userId,name FROM user WHERE name=9527 LIMIT 10

Currently only supports SELECT and UPDATE, now tring to support DELETE and JOIN.

Ctrl + c can’t terminate running query because I haven’t figure out how to do this.

After some digging, there is a context package for golang,
howerver it can't quit a running function unless the function 
is checking context.Done()on every step of its body.

This can be used to just ignore current running query, 
but the query will continue in the background.

I suppose it's not possible to cancel the request after the request is sent,
so maybe consider a rollback action?

Version 0.0.4 supports ctrl+c to ignore running query.

Which will be handy when that pm tells you to change somebody’s coins to 2^10.


Road Map

Mostly all that TODO in the code, and tell others about this project.

Apparently from the go report page, there is quiet a lot things to fix, but not sure should fix that.

Better error handle, for example if a SQL is invalid, should suggest what’s wrong.
