Abstract: The present disclosure describes hybrid transactional and analytical processing (HTAP) techniques. A HTAP system comprises a first processing engine configured to perform online transactional processing, a second processing engine configured to perform online analytical processing, and a storage in communication with the first processing engine and the second processing engine. The first processing engine, the second processing engine, and the storage may be modularized and configured to be decoupled from each other. The system may be configured to capture data by the first processing engine in real time, organize the data in a first format in a first part of the storage for use by the first processing engine, propagate the data to a second part of the storage subsystem, and organize the data in a second format in the second part of the storage for use by the second processing engine.

Abstract: The present disclosure describes storage techniques for hybrid transactional and analytical processing. Data captured by a first processing engine may be received. The first processing engine may be configured to perform online transactional processing). Multiple replicas of logical logs generated based on the data may be distributed to a Delta Store by applying a quorum protocol on the multiple replicas. Data in the Delta Store are stored in a row format and are visible to a query for online analytical processing performed by a second processing engine. Data may be flushed from the Delta Store to a Base Store based on one or more predetermined rules. Data in the Base Store are stored in a columnar format and may be accessible by the second processing engine.

Abstract: The present disclosure describes techniques of providing data consistency for hybrid transactional and analytical processing. Logical logs and log serial numbers (LSNs) associated with the logical logs may be generated based on data captured by a first processing engine. The logical logs and the LSNs may be propagated to a storage subsystem configured to be in communication with the first processing engine and a second processing engine. The LSNs and information indicative of LSN schema versions may be stored and distributed by a metadata service. The first processing engine, the second processing engine, the storage subsystem and the metadata service are modularized, and support a LSN mechanism for maintaining data consistency.

Abstract: System and method of training a machine learning model on a plurality of devices in parallel are provided. The method includes performing a model profiling execution before a model normal execution, allocating (360) tensors of the model into a plurality of chunks based on profiling results from the model profiling execution, and performing the model normal execution on the plurality of devices in parallel to train or fine-tune the model.

Abstract: The present disclosure relates to a database-based data processing method, device, medium, and apparatus, the method including: receiving a target query statement; determining a corresponding target materialized view for executing the target query statement according to a data query time corresponding to the target query statement and a time granularity of the materialized view in a database, wherein the database is constructed with the materialized view at different time granularities; rewriting the target query statement according to the time granularity of the target materialized view to obtain a plurality of target sub-query statements, wherein the target sub-query statements include sub-query statements which are queried based on the target materialized view; and merging the target sub-query statements, and performing a data query according to a query statement obtained by merging.
