Abstract: Methods and systems for implementing ranged operations in a distributed computing system are provided. A write operation is received from a client device, wherein the write operation is configured to associate a range key and range key value with a range of key-value (KV) pairs included in a sorted key space, wherein the range corresponds to a key span of the sorted key space defined by a start boundary key and an end boundary key. A range key and range key value is written for the range based on the write operation, wherein an iterator is configured to read a respective value of a KV pair of the range and/or the range key value based on a position of the iterator within the key span.

Abstract: Systems and methods for encoding block properties for data structures and filtering data structures using block properties are provided. A group of a plurality of key-value entries can be added to a data block of a data file. A block property indicative of attributes of the group of the plurality of key-value entries can be determined. The block property can be encoded in a block handle and added to an index block of the data file. A query directed to a plurality of data files can be received from a client device. A target block property included in the query can be compared to a block property corresponding to a data block of a data file of the plurality of data files. Based on the target block property intersecting with the block property of the data block, values corresponding to the data block can be sent to the client device.
