The invention discloses a gray release realization method, device and
system and a computation node. The method comprises the following steps of:
processing a received application request and determining the received application request as a gray request; analyzing the gray request according to preset
shard configuration information, and determining the gray request as a first gray request for requesting gray data or a second gray request for requesting gray data and official data; partially forwarding data for requesting a gray user in the first gray request or the second gray request to a gray
data node where the gray user corresponding to the gray request is located to carry out execution; and partially forwarding the data for requesting an official user in the second gray request to anofficial
data node where the official user is located to carry out execution. Through the method, gray users and official users are differentiated at
database layers, so that the aim of gray releaseis simply and effectively achieved, and the
business transformation amount is decreased at the same time.
