Abstract: Disclosed herein is an apparatus for processing a predictive spatiotemporal query based on synthetic data. The apparatus includes a query-processing unit for analyzing a predictive spatiotemporal query of a user and returning a processing result, a machine-learning unit for training a machine-learning model in response to a request from the query-processing unit and generating synthetic spatiotemporal data based on the machine-learning model, and a data storage unit for storing raw spatiotemporal data and the generated synthetic spatiotemporal data, and the raw spatiotemporal data may be stored in the form of a table including an identifier column and a position column.

Abstract: The following description relates to a query optimization method in distributed query engine and an apparatus thereof. A query optimization method according to an exemplary embodiment includes establishing a query plan based on query; classifying data to be included in result data of a high level operation from result data of a low level operation as a first data to be used for intermediate operations existing between the low level operation and the high level operation and a second data not to be used for the intermediate operations, based on the query plan; and modifying the query plan for the second data not to be an input value for the intermediate operations
