The present application relates to the technical field of
distributed database, specifically to an airborne data
digital recording method based on
distributed database, comprising the following steps: monitoring flight
phase state word, switching to freeze writing and generating boundary sampling
anchor point, boundary
bus anchor point and target phase identifier, sending boundary frame, adjusting
shard mapping after reaching boundary, unfreezing after checking consistency, sorting and checking continuity at the end of the flight segment, and forming the final
shard mapping table, in the present application, the flight
phase state word switching triggers collection freezing, and the boundary is anchored by the sampling serial number,
bus frame incremental serial number and target phase identifier, so that the
shard switching is consistent with the real sampling and message process, the data to be sent is pre-marked by the boundary
anchor point, the shard mapping is adjusted after comparison by the local serial number on the writing side, and the collection is recovered through boundary consistency check, which can reduce phase mismatch, shard overlap and trace determination cost.
