About partitionKey and rowKey

You can formatting value of partitionKey and rowKey.

"partitionKey": "Any value of the fixed"

You will output the value of any directly. In the following example, The partitionKey combined FirstName and LastName attribute of SimpleDB.

"partitionKey": "%FirstName% %LastName%"

Special identifier

Identifier Value
"%$ItemName%" ItemName() row of AWS SimpleDB.
"%$Identity%" Sequence number of zero origin.
"%$Guid%" Generate new GUID.

It is also possible to use a combination of several of these features.

"Azure_%Guid%_%FirstName%_%Identity%"

If the value of the Attribute FirstName of SimpleDB was ** PNOP **, PartitionKey similar to the following is generated.

"Azure_ACBB16CA-E78D-3B13-041-3CD2-8CC57221_PNOP_0"

About type key

When you import, you can specify the type explicitly. The sdb2aztbl will import as a Edm.String If not specified. The type can be one of the following types that can be specified in the Windows Azure.

  • Edm.String
  • Edm.Int32
  • Edm.Int64
  • Edm.Double
  • Edm.Boolean
  • Edm.Guid
  • Edm.DateTime

Notes: You do not designate type a partitionKey and rowKey.
