Abstract: The subject technology receives blob metadata from a key-value store. The subject technology retrieves a blob file from a blob store based on the blob metadata; the blob file comprises at least one of a snapshot file or a delta file. The subject technology transforms the blob file from a first format to a column file format, the transformation comprising converting data from the blob file to rowsets and writing the rowsets into a file in the column file format. The subject technology stores the file in a local cache.

Abstract: The subject technology receives, by an execution node, blob metadata from a key-value store, the blob metadata including information related to a set of blob files. The subject technology determines, by the execution node using the blob metadata, whether a copy of each of the set of blob files is stored in a local cache of the execution node. The subject technology transforms at least one blob file, retrieved from a blob store, to a second file in a column file format, the at least one blob file being in a first format that is different than the column file format, the transforming comprising at least converting a particular snapshot file from the at least one blob file to a particular set of rowsets and writing the set of rowsets into the second file in the column file format. The subject technology stores the second file in the local cache.

Abstract: The subject technology receives a query, the query including a query range for processing the query. The subject technology sends a request to a key-value store for blob metadata and a set of recent writes for the query range. The subject technology receives the blob metadata, the blob metadata including information related to a set of blob files. The subject technology determines whether the set of blob files is stored in a local cache. The subject technology, in response to at least one blob file being missing from the set of blob files, sends a request to a blob store to retrieve the at least one blob file of the set of blob files. The subject technology transforms the retrieved at least one blob file to a column file format. The subject technology stores the transformed at least one blob file in the local cache.

Abstract: A method and system for processing a bit-packed array using one or more processors, including determining a data element size of the bit-packed array, determining a lane configuration of a single-instruction multiple-data (SIMD) unit for processing the bit-packed array based at least in part on the determined data element size, the lane configuration being determined from among a plurality of candidate lane configurations, each candidate lane configuration having a different number of vector register lanes and a corresponding bit capacity per vector register lane, configuring the SIMD unit according to the determined lane configuration, and loading one or more data elements into each vector register lane of the SIMD unit. SIMD instructions may be executed on the loaded one or more data elements of each vector register lane in parallel, and a result of the SIMD instruction may be stored in memory.

Abstract: A pipeline apparatus comprising a pipe body. The pipe body includes an annular cavity between annular innermost and outermost fluid impermeable barrier layers. The pipe body further includes a plurality of armour wires which extend along at least part of the length of the pipe body in the annular cavity. The plurality of armour wires include a first armour wire which is electrically isolated from the other armour wires along at least part of the length of the armour wires. The pipe body also includes a measurement device which is arranged to electrically couple to the first armour wire at a first end of the pipe body. The measurement device is arranged to measure the electrical impedance of the first armour wire, wherein variation of the electrical impedance of the first armour wire is indicative of a defect of the first armour wire.
