A method and apparatus for DDL synchronization in group execution

This invention relates to the field of database synchronization technology, and provides a method and apparatus for DDL synchronization executed in groups. The method involves receiving log information and classifying it into multiple transactions, then further classifying these transactions into at least one ordinary group or DDL group to obtain first transactions and second transactions. Committed but not yet entered into the database are retrieved from all the ordinary groups, and these first transactions are entered into the database. After the first transactions in the corresponding ordinary groups are entered into the database, the committed but not yet entered second transactions in the DDL groups are also entered into the database. This invention, by setting up separate DDL groups, temporarily withholds second transactions that cannot find dependent database objects from the database until the dependent database objects are created, thus avoiding synchronization failures due to transactions that cannot find dependent database objects. This addresses the problem that unsuccessful synchronization of interdependent database DDL operations may cause data synchronization errors.

Database cardinality estimation method and program product based on query embedding

This application discloses a database cardinality estimation method and program product based on query embedding, relating to the field of database processing technology. The database cardinality estimation method based on query embedding extracts features of data distribution information through a data distribution embedding module, enabling cardinality estimation to perceive changes in data distribution in real time. It also extracts semantic features of database query statements through a query statement embedding module, allowing cardinality estimation to rely on stable features in the database schema (such as data distribution and column correlation) for inference even when features are missing, reducing the risk of overfitting the cardinality estimation model to surface-level query semantics. Furthermore, it identifies the correlation between query semantics and data distribution through an attention mechanism, and the features of both are weighted and fused to generate a query feature vector. This generated query feature vector simultaneously contains the semantic logic of the query intent and the real-time state of the data environment, improving the robustness of cardinality estimation.
