Distributed database processing method and device

An apparatus, comprising:

• a processor;
• and
• a non-transitory computer readable medium connected to the processor and having stored thereon instructions that, when executed, cause the processor to:
• receive a first access request for a first data table, wherein the first access request comprises a first query index field, a value of the first query index field, and a to-be-accessed first target field, wherein the first query index field is non-partition information of the first data table;
• obtain multiple partition routing tables associated with the first data table;
• determine, from the multiple partition routing tables associated with the first data table, a first partition routing table that is associated with non-partition information;
• and
• obtain, from the first partition routing table that is associated with non-partition information, partition information and values of the partition information;
• wherein the first partition routing table stores correspondences between the values of the partition information and values of the non-partition information;
• and
• send, according to the partition information and the value of the partition information, the first access request to a database corresponding to the partition information and the value of the partition information.
