Information acquisition method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention provides an information acquisition method and device, electronic equipment and a storage medium, and is applied to a transaction manager, a plurality of links are established between the transaction manager and a central time service node, and the information acquisition method comprises the following steps: sending each timestamp acquisition request for a transaction to the central time service node through the plurality of links, after receiving each timestamp acquisition request, generating and feeding back a response result of the timestamp acquisition request; when the response result of any timestamp acquisition request is received, searching for each target transaction from the transactions which are not allocated with the timestamps at present, wherein the generation time of the timestamp acquisition request of any target transaction is not later than the generation time of the timestamp acquisition request corresponding to the response result; and if the response result is found, allocating the timestamp represented by the response result to each target transaction. According to the scheme, the timestamp obtaining efficiency can be improved, and the timestamp effectiveness can be ensured.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to an information acquisition method, device, electronic equipment and storage medium. Background technique [0002] In a distributed database, TM (Transaction Manager, transaction manager) needs to obtain the transaction start time stamp and transaction commit time stamp from the central timing node when the transaction is opened and committed, so as to use the obtained time stamp to perform transaction processing. [0003] In related technologies, when obtaining the timestamp from the central timing node, the acquisition request is transmitted based on a link between the transaction manager and the central timing node, so that: the next acquisition request waits for the result of the previous acquisition request to return , the next acquisition request can be sent, so a high queuing delay is generated for timestamp acquisition. [0004] How to improve the efficiency of...
