QueryAsync(string, Dictionary<string, AttributeValue>, string, Func<Dictionary<string, AttributeValue>, TResult>, string, bool, Dictionary<string, AttributeValue>, bool)
public Task<(List<TResult> results, Dictionary<string, AttributeValue>? lastEvaluatedKey)> DynamoDBStorage.QueryAsync<TResult>(string tableName, Dictionary<string, AttributeValue> keys, string keyConditionExpression, Func<Dictionary<string, AttributeValue>, TResult> resolver, string indexName = "", bool scanIndexForward = true, Dictionary<string, AttributeValue>? lastEvaluatedKey = null, bool consistentRead = true) Query for multiple entries in a DynamoDB table by filtering its keys
Parameters
tableNamestring- The name of the table to search for the entries
keysDictionary<string, AttributeValue>- The table entry keys to search for
keyConditionExpressionstring- the expression that will filter the keys
resolverFunc<Dictionary<string, AttributeValue>, TResult>- Function that will be called to translate the returned fields into a concrete type. This Function is only called if the result is != null and will be called for each entry that match the query and added to the results list
indexNamestring- In case a secondary index is used in the keyConditionExpression
scanIndexForwardbool- In case an index is used, show if the seek order is ascending (true) or descending (false)
lastEvaluatedKeyDictionary<string, AttributeValue>- The primary key of the first item that this operation will evaluate. Use the value that was returned for LastEvaluatedKey in the previous operation
consistentReadbool- Determines the read consistency model. Note that if a GSI is used, this must be false.
Returns
The collection containing a list of objects translated by the resolver function and the LastEvaluatedKey for paged results
