Options for listing key-value pairs in a
The maximum number of key-value pairs to return. If not specified, all matching key-value pairs will be returned.
The cursor to resume the iteration from. If not specified, the iteration will start from the beginning.
Whether to reverse the order of the returned key-value pairs. If not
specified, the order will be ascending from the start of the range as per
the lexicographical ordering of the keys. If
true, the order will be
descending from the end of the range.
The default value is
The consistency level of the list operation. The default consistency
level is "strong". Some use cases can benefit from using a weaker
consistency level. For more information on consistency levels, see the
List operations are performed in batches (in sizes specified by the
batchSize option). The consistency level of the list operation is
applied to each batch individually. This means that while each batch is
guaranteed to be consistent within itself, the entire list operation may
not be consistent across batches because a mutation may be applied to a
key-value pair between batches, in a batch that has already been returned
by the list operation.
The size of the batches in which the list operation is performed. Larger or smaller batch sizes may positively or negatively affect the performance of a list operation depending on the specific use case and iteration behavior. Slow iterating queries may benefit from using a smaller batch size for increased overall consistency, while fast iterating queries may benefit from using a larger batch size for better performance.
The default batch size is equal to the
limit option, or 100 if this is
unset. The maximum value for this option is 500. Larger values will be
