Asynchronous deletion in non-relational databases

An apparatus for handling data object associations within a non-relational database, comprising:

• a processor,
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• store, at the non-relational database, a plurality of data object associations, wherein each association of the plurality of data object associations corresponds to a data object relational index stored in a relational database;
• receive, at the non-relational database, a read request indicating a first data object identifier;
• identify a second data object identifier according to a first data object association of the stored plurality of data object associations that is indexed in the non-relational database with the first data object identifier;
• determine that a last data entry that is indexed in the non-relational database with the identified second data object identifier and is associated with the first data object identifier has been deleted from the non-relational database;
• and
• delete the first data object association from the non-relational database in response to the read request and based at least in part on the determining.

A non-transitory computer-readable medium storing code for handling data object associations within a non-relational database, the code comprising instructions executable by a processor to:

• store, at the non-relational database, a plurality of data object associations, wherein each association of the plurality of data object associations corresponds to a data object relational index stored in a relational database;
• receive, at the non-relational database, a read request indicating a first data object identifier;
• identify a second data object identifier according to a first data object association of the stored plurality of data object associations that is indexed in the non-relational database with the first data object identifier;
• determine that a last data entry that is indexed in the non-relational database with the identified second data object identifier and is associated with the first data object identifier has been deleted from the non-relational database;
• and
• delete the first data object association from the non-relational database in response to the read request and based at least in part on the determining.
