Tried using your script but it hangs on a dynamodb-local . Here is the modified script I was trying to use.
https://github.com/djangofan/dynamodb-copy-table

Here is how you can setup the local dynamodb:

1. docker run -p 8000:8000 --name dynamodb-local --restart unless-stopped -d dwmkerr/dynamodb -sharedDb
2. aws dynamodb create-table --table-name Music --attribute-definitions AttributeName=Artist,AttributeType=S AttributeName=SongTitle,AttributeType=S --key-schema AttributeName=Artist,KeyType=HASH AttributeName=SongTitle,KeyType=RANGE --provisioned-throughput ReadCapacityUnits=1,WriteCapacityUnits=1
3. aws dynamodb list-tables --endpoint-url http://192.168.99.100:8000
4. then , try to copy it with this command:
   python dynamodb-copy-table.py Music copyof-Music true

This python script doesn't clone the empty object.

Indexes are an important part of a table schema, are a far more tedious part of table creation than the table itself. This would be much more useful if it copied indexes

@jakelodwick @techgaun

given a source table of x read throughput and a dest table of <x write throughput, this utility will result in throttled writes, which means the throttled data will not be copied to dest.

The converse of this could also exist: a throttled read resulting in nothing returned, which then never gets written.

Am I observing this correctly, or am I missing something?

If so, I may be able to do a PR For something to fix it. Let me know.

Hey there. Thanks a lot for making this repo, very helpful. Wish Amazon provided an easy way to do this!

Noticed an issue though: seems like Booleans are converted to Numbers.

Here's an entry in my source table:

...and now the destination table:

Note that the public and the tiles[0].trigger.sync parameters have changed from true to 1. Fortunately, false becomes 0 in other cases, so we can probably guess what's happening.

Should be easy enough fix manually on my end with a DynamoDB query, but thought you should be aware!

It would be nice to just get a limited number of records instead of the whole table.

I use the docker command provided in the Readme. I keep getting the following error:

Traceback (most recent call last):
  File "dynamodb-copy-table.py", line 22, in <module>
    ddbc = DynamoDBConnection()
  File "/usr/local/lib/python3.6/site-packages/boto/dynamodb2/layer1.py", line 173, in __init__
    kwargs['host'] = region.endpoint
AttributeError: 'NoneType' object has no attribute 'endpoint'

I have initialized all the required environment variables.

Source table:

Partition key
scheduleId (Number)
Sort key
timestamp (Number)

Command:

docker run --rm -v $HOME/.aws:/root/.aws -it techgaun/dynamodb-copy-table:latest source dest

Destination table:

Partition key
scheduleId (String)
Sort key
timestamp (String)

LocalSecondaryIndexes is missing from the schema.

GlobalSecondaryIndexes is missing as well, but that one could be created later

Hi there,

I have used this script several times and it is working just fine.
Though, I think it would be nice to have a Dockerfile and ability to run this script in container.
