Abstract

The invention relates to the field of data connection, and discloses a database connection pool conversion method, device and equipment and a storage medium. The method comprises the following steps: receiving a connection request of a first data node in the data node cluster; judging whether the first data node has session binding setting or not; if not, connecting the first data node to a second data node corresponding to the connection request based on a preset global connection pool; and if yes, connecting the first data node to a second data node corresponding to the connection request according to a preset specific connection algorithm.

Description

technical field [0001] The invention relates to the field of data connection, in particular to a database connection pool conversion method, device, equipment and storage medium. Background technique [0002] In an MPP distributed database, it usually consists of a coordinating node and a data node cluster. The coordinating node is responsible for client access, and each client will create a session after connecting to the coordinating node. Session maintenance refers to session information, which is responsible for receiving SQL from the client, generating an execution plan and sending it to the data node for execution. In order to improve performance, the coordinating node often uses a connection pool to manage the connection with the data node cluster. In a common connection pool, there is no relationship between connections and sessions, but for some operations and transactions, it is necessary to ensure that all operations in a session transaction are executed in the s...
