A fast query method and system for real-time database filtering expression

PendingCN122387951AReal-time dataOriginal data
This invention discloses a fast query method and system for real-time database filtering expressions, belonging to the field of industrial real-time data query technology. The method parses the original filtering expression into atomic predicates and generates unique sub-condition identifiers, creates corresponding Boolean derived test points and establishes mapping relationships. During the data writing stage, the atomic predicates of each piece of real-time data are determined in real time, and the Boolean results are written to the derived test points. This fundamentally solves the problems in existing technologies where different queries share the same sub-conditions but require repeated calculations each time, and the cost increases linearly with the data volume due to the query side calculating massive amounts of original data line by line. Furthermore, the atomic predicates in the original expression are replaced with corresponding Boolean derived test points to generate a rewritten expression, and set logic operations are directly performed on the pre-stored Boolean results in each derived test point to obtain the final query result, thereby transforming the complex comparison calculations on the query side into efficient set operations.

AI Agent Tool's Loop Checkpoints and Document Content Block-Level Atomic Rollback Method and System

This invention discloses a method and system for cyclic checkpointing and atomic rollback at the document content block level in an AI Agent tool. Before and after each AI Agent tool call, the current content block sequence of the document is automatically captured, generating checkpoints associated with the tool call identifier. These checkpoints are linked in execution order to form an ordered checkpoint chain, and a head pointer is maintained. Upon responding to a rollback request, the content block sequence of the specified checkpoint is atomically deep-copied to replace the current content block sequence of the document. The content block-level structural difference algorithm uses the unique identifier of the content block as the comparison key, identifies addition, deletion, and modification operations through set operations, and employs a lazy computation strategy to reduce overhead. The incremental snapshot compression strategy reduces memory usage from O(N×D) to O(N×ΔD), saving approximately 99% of memory in typical scenarios.
