Adds a KeyConditionExpression from a ConditionExpression to a DynamoDBQuery Must be in the form of <Condition1> && <Condition2> where format of <Condition1> is:

Adds a KeyConditionExpression from a ConditionExpression to a DynamoDBQuery Must be in the form of <Condition1> && <Condition2> where format of <Condition1> is:

<ProjectionExpressionForPartitionKey> === <value>

and the format of <Condition2> is:

<ProjectionExpressionForSortKey> <op> <value>

where op can be one of ===, >, >=, <, <=, between, beginsWith

Example using type safe API:

// email and subject are partition and sort keys respectively
val (email, subject, enrollmentDate, payment) = ProjectionExpression.accessors[Student]
// ...
val newQuery = query.whereKey(email === "avi@gmail.com" && subject === "maths")
