Query for attributes containing '-' fails

[martin-macak]

Description

When query contains attribute with - in name then it fails with following error:

ValidationException
Invalid KeyConditionExpression: Syntax error; token: "-", near: "GI-1"

This is caused by not masking ExpressionAttributeNames with valid values. This is btw. the same error that competing product Dynobase has. This is killer, because it makes plugin unusable for most of tables that follow this naming convention. It's extremely inconvenient as AWS encourages developers to name their entities and attributes in DNS compliant way, which contains - character.

Steps to reproduce

• Create table with GI named GI-1-PK
• Scan for table in DynamoDB plugin
• Fill in query GI-1-PK = "A"

Suggestion for fix

Use ExpressionAttributeNames to rename all attributes to safe names

Seems like query is constructed like

Query
{
  "Limit": 50,
  "KeyConditionExpression": "GI-1-PK = :partitionKeyVal",
  "ExpressionAttributeValues": {
    ":partitionKeyVal": {
      "S": "A"
    }
  },
  "IndexName": "GI-1",
  "TableName": "Table-dev-v1"
}

So it should be super easy to add ExpressionAttributeNames
