Input for the Query operation.

Fields

table_name: String

The name of the table to query.

index_name: Option<String>

The name of a secondary index to query.

key_condition_expression: Option<String>

The condition that specifies the key values for items to be retrieved.

filter_expression: Option<String>

A string that contains conditions for filtering the query results.

projection_expression: Option<String>

A string that identifies the attributes to retrieve from the table.

expression_attribute_names: HashMap<String, String>

Substitution tokens for attribute names in an expression.

expression_attribute_values: HashMap<String, AttributeValue>

Substitution tokens for attribute values in an expression.

scan_index_forward: Option<bool>

Specifies the order of index traversal. true (default) for ascending, false for descending.

limit: Option<i32>

The maximum number of items to evaluate (not necessarily the number of matching items).

exclusive_start_key: HashMap<String, AttributeValue>

The primary key of the first item that this operation will evaluate. Used for pagination.

select: Option<Select>

The attributes to be returned in the result.

consistent_read: Option<bool>

If true, a strongly consistent read is used.

return_consumed_capacity: Option<ReturnConsumedCapacity>

Determines the level of detail about provisioned throughput consumption.

key_conditions: HashMap<String, Condition>

Legacy: key conditions (use key_condition_expression instead).

query_filter: HashMap<String, Condition>

Legacy: query filter (use filter_expression instead).

attributes_to_get: Option<Vec<String>>

Legacy: attribute names to retrieve (use projection_expression instead).

conditional_operator: Option<ConditionalOperator>

Legacy: logical operator for combining multiple query filter conditions.
