Abstract: The invention discloses an electrolyte solution containing lithium salt, an organic solvent, and additives. The additives include vinylene carbonate and 2,6-di-tert-butyl-4-methylphenol; the content of vinylene carbonate accounts for 0.5% to 5% of the total mass of the electrolyte, and the content of 2,6-di-tert-butyl-4-methylphenol accounts for 7*10?4% to 1.6% of the total mass of vinylene carbonate. The electrolyte of the invention can improve the film formation rate and film thickness of vinylene carbonate in the negative electrode, so that the obtained SEI film resistance is smaller, thereby improving the performance of the lithium battery.

Abstract: Embodiments relate to aggregation operations. More specifically, embodiments relate to enforcing an aggregation constraint across a distributed network of compute nodes responding asynchronously. Each compute node individually processes the local partial aggregate value in parallel and asynchronously communicates with a conflict resolution node (CRN).

Abstract: One embodiment provides for a method including performing, by a processing thread, a process that analyzes transactional operations by maintaining the transactional operations in transaction local side logs, and waiting until a successful transaction commit to append the transaction local side logs to a log stream. The processing thread processes the transactional operations on a key used to determine whether existing data is found for the key. The transactional operations are sped up through parallelism based on partitioning tables across nodes handling the transactional operations. A first process is performed by a first processor that processes updates for values of a key based on updating a first start time table index using unique keys and a start time field of a row for a first appearance of each unique key from the transactional operations.

Abstract: A method and system of processing graph query are provided. A graph query is received by a relational database graph module. The graph query is translated into one or more relational database queries. One or more relational database queries are translated to be performed on data stored within a relational database. One or more results from the relational database are received based on the sent one or more relational database queries. A synergistic graph is generated on a display, based on the received one or more results.

Abstract: According to one or more embodiments of the present invention, a computer-implemented method includes creating a hybrid index for a multi-zone data storage system in which a first zone has data that is organized for transaction processing, and a second zone that has data organized for analytic processing. Each index entry in the hybrid index includes an index key including an equality column, a begin-timestamp column, and a tuple-sequence-number column. The method further includes building an index run to be included in the hybrid index, the index run includes multiple index entries. An index run is created by selecting columns by scanning data blocks from the first zone, computing tuple-sequence-number values for the index entries to be included in the hybrid index, and sorting the index entries according to a predetermined order using the columns to be included in the index run.

Abstract: Embodiments of the invention relate to executing graph path queries. A database stores data entities and attributes in node tables and stores links between nodes in an edge table. Edges form a path between a source node and a target node. A source node set is generated and joined with the edge table to produce a first intermediate set. Similarly, a target node set is generated and joined with the edge table to produce a second intermediate set. A result path is generated through a joining of the first and second intermediate paths and application of a length condition.
