Big segments, seperate DynamoDB tables per environement and autoconfiguration

[hughevans]

Big segment data does not populate the DynamoDB when you use this configuration combination:

1. Autoconfiguration and supplying ENV_DATASTORE_TABLE_NAME="table-name-$CID"
2. USE_DYNAMODB="true"

You end up with this in the logs:

BigSegmentSynchronizer: Synchronization failed: InvalidParameter: 1 validation error(s) found.
- minimum field size of 3, GetItemInput.TableName.

That’s an AWS error from calling DynamoDB GetItem with a blank TableName.

I think the issue is that on this line you’re using the table name from allConfig and not envConfig.

Apart from the big segments everything else has been functioning fine with this Relay Proxy.

Perhaps big segments only works with DynamoDB if you use a single table for all environments?

That does look like a mistake - thanks for reporting it. We'll look into it and if that's right, it should be a simple fix that we can release a patch for soon.

The 6.7.12 release should fix this. I'll close the issue but please feel free to reopen if you still see a similar issue.
