Transaction read-write separation method and device

The invention relates to the technical field of transaction read-write separation, in particular to a transaction read-write separation device, which comprises a data source selection unit, a transaction link and a routing unit, and is characterized in that the data source selection unit consists of a transaction configuration module, a data source configuration module, a data source management module, a data source selection module and a data source difference detection module; the invention also discloses a transaction read-write separation method. The method comprises the following steps: S11, registering requirements of a read-only data source and a read-write data source; S12, loading transaction configuration information; S13, distributing a data source; S14, obtaining read-only data; S15, adding the obtaining logic of the node data gap; and S16, obtaining read-write data. The transaction configuration module, the data source configuration module, the data source management module, the data source selec
