Abstract: This application provides an optical module, an electronic device, a communication system, and a related processing method. The optical module includes: a first processing unit, and a sampling unit, a sampled information storage unit, and a fault information storage unit that are separately electrically connected to the first processing unit. The sampling unit is configured to collect first sampled parameters, and store the first sampled parameters in the sampled information storage unit by using the first processing unit. The first processing unit is configured to: when identifying alarm information, read the first sampled parameters in the sampled information storage unit, determine, based on the first sampled parameters, fault type information corresponding to the alarm information, and store the fault type information in the fault information storage unit. The optical module does not need to transmit a large amount of sampled data to the electronic device.

Abstract: A query processing method including decomposing an SQL into logical plans based on data source feature information, to obtain a logical plan set, where the data source feature information is stored in an internal storage space of the query engine; generating physical plans for the logical plan set based on the data source feature information, to obtain a physical plan set; determining query costs of the physical plan set based on the data source feature information, to obtain a physical plan with a highest priority; and executing the physical plan with the highest priority, to obtain a query result queried by a user. The embodiments of this application further disclose a data source registration method and a query engine.

Abstract: a query processing method including decomposing an SQL into logical plans based on data source feature information, to obtain a logical plan set, where the data source feature information is stored in an internal data source feature library of a query engine, and the internal data source feature library is stored in cache space of the query engine; generating physical plans for the logical plan set based on the data source feature information, to obtain a physical plan set; determining query costs of the physical plan set based on the data source feature information, to obtain a physical plan with a highest priority; and executing the physical plan with the highest priority, to obtain a query result queried by a user. The embodiments of this application further disclose a data source registration method and a query engine.
