Container storage management system

A non-transitory, computer-readable medium coupled to one or more processors and having instructions stored thereon which, when executed by the one or more processors, cause the one or more processors to perform operations, the operations comprising:

• generating a hierarchy of metadata tables for a database comprising containers including data stored in tables, wherein the tables are identified by table names and assigned to a corresponding one or more containers, wherein a first table assigned to two containers defines two table instances of the first table storing different data in the two containers, wherein generating the hierarchy of metadata tables comprises:
• generating a first metadata table defining mappings between container identifiers, table names, table sections, and unique identifiers for corresponding data within table sections of table instances defined with the table names mapped to the container identifiers;
• generating a third metadata table defining mappings between container identifiers and table names;
• and
• generating a fourth metadata table identifying quantity of tables and table size in relation to the containers;
• in response to receiving a request to generate a replication of table content from a set of the containers from the database, generating a second metadata table to identify a unique set of table instances from the set of the containers based on evaluating the first metadata table, wherein the unique set of table instances comprises data from the database without repetition;
• and
• based on evaluating the generated second metadata table, providing the unique set of table instances identified in the second metadata table for performing data replication.
