Zusammenfassung: | The invention provides a connection querying method of multiple time sequences under column-type storage. The method includes: dividing the multiple time sequences of column-type storage into multipleto-be-queried sequences and multiple filtering sequences, wherein the time sequences include time stamp sequences and data value sequences; screening out time stamps, which are of each filtering sequence and meet preset filtering conditions, from a time stamp sequence of each filtering sequence; and traversing the queried sequences on the basis of the time stamps, which are of each filtering sequence and meet the preset filtering conditions, to acquire a connection querying result, wherein the connection querying result is time stamps of the queried sequences and data values corresponding tothe time stamps of the queried sequences. According to the connection querying method and a connection querying system of the multiple time sequences under column-type storage provided by the invention, the times tamps meeting |
