Cache access mechanism

A non-transitory machine-readable storage medium having instructions stored therein, which when executed by a machine, cause the machine to perform a method, the method comprising:

• providing a plurality of cache application programming interfaces (APIs) within an object relational mapping (ORM) system for mapping a data object of object-oriented programming application to a data entry of a relational database, wherein the data object of the object-oriented programming application is incompatible with a format of the relational database, and wherein the object relational mapping system is configured to convert the data object to a structured query language (SQL) query that is specifically tailored to the format of the relational database, wherein the SQL query is transmitted from the ORM system to the relational database as a database transaction for accessing the data entry requested by the data object of the object-oriented programming application;
• in response to a first cache request received at a first cache API associated with a transaction for updating a data entry of the relational database, storing the updated data of the data entry in a local cache, the local cache being one of a plurality of members of a cache cluster, and sending an invalidation message to remaining members of the cache cluster to invalidate corresponding cache entries of the remaining members;
• and
• in response to a second cache request received at a second cache API associated with a transaction for loading data from a data entry of the relational database, storing the loaded data in the local cache without sending an invalidation message to the remaining members of the cache cluster, wherein the first cache API is separated and different from the second cache API.

An apparatus for mapping a data object of object-oriented programming application to a data entry of a relational database, the apparatus comprising:

• a cache cluster;
• and
• hardware processing logic to:
• in response to a first cache request received via a first cache application programming interface (API) associated with a transaction for updating a data entry of the relational database, store the updated data of the data entry in a local cache, the local cache being one of a plurality of members of a cache cluster, and to send an invalidation message to remaining members of the cache cluster to invalidate corresponding cache entries of the remaining members;
• and
• in response to a second cache request received via a second API associated with a transaction for loading data from a data entry of the relational database, store the loaded data in the local cache without sending an invalidation message to the remaining members of the cache cluster, wherein the second cache API is separated and different from the first cache API, wherein the data object of the object-oriented programming application is incompatible with a format of the relational database, and wherein the data object is converted to a structured query language (SQL) query that is specifically tailored to the format of the relational database for accessing the relational database.

A computer-implemented method, comprising:

• providing a plurality of cache application programming interfaces (APIs) within an object relational mapping (ORM) system of a database server associated with a relational database, the ORM system configured to map a data object of an object oriented programming application programmed in an object-oriented programming language to a data entry of the relational database, wherein the data object of the object-oriented programming application is to request accessing a data entry of the relational database and is incompatible with a format of the relational database;
• converting, by the ORM system, the data object to a structured query language (SQL) query that is specifically tailored to the format of the relational database, in response to the data object;
• transmitting the SQL query from the ORM system to the relational database as a database transaction for accessing the data entry requested by the data object of the object-oriented programming application;
• in response to a first cache request received at a first of the cache APIs of the ORM system of the database server, the first cache request being associated with a first database transaction for updating a first data entry of the relational database, storing the updated data of the first data entry in a local cache, the local cache being one of a plurality of members of a cache cluster, and sending an invalidation message to remaining members of the cache cluster to invalidate corresponding cache entries of the remaining members;
• and
• in response to a second cache request received at a second of the cache APIs of the ORM system of the database server, the second cache request being associated with a second database transaction for loading data from a second data entry of the relational database, storing the loaded data in the local cache without sending an invalidation message to the remaining members of the cache cluster, wherein the first cache API is separated and different from the second cache API maintained by the ORM system of the database server as a single server.

A non-transitory machine-readable storage medium having instructions stored therein, which when executed by a machine, cause the machine to perform a method, the method comprising:

• providing a plurality of cache application programming interfaces (APIs) within an object relational mapping (ORM) system of a database server associated with a relational database, the ORM system configured to map a data object of an object oriented programming application programmed in an object-oriented programming language to a data entry of the relational database, wherein the data object of the object-oriented programming application is to request accessing a data entry of the relational database and is incompatible with a format of the relational database;

• transmitting the SQL query from the ORM system to the relational database as a database transaction for accessing the data entry requested by the data object of the object-oriented programming application;
• in response to a first cache request received at a first of the cache APIs of the ORM system of the database server, the first cache request being associated with a first database transaction for updating a first data entry of the relational database, storing the updated data of the first data entry in a local cache, the local cache being one of a plurality of members of a cache cluster, and sending an invalidation message to remaining members of the cache cluster to invalidate corresponding cache entries of the remaining members;
• and
• in response to a second cache request received at a second of the cache APIs of the ORM system of the database server, the second cache request being associated with a second database transaction for loading data from a second data entry of the relational database, storing the loaded data in the local cache without sending an invalidation message to the remaining members of the cache cluster, wherein the first cache API is separated and different from the second cache API maintained by the ORM system of the database server as a single server.
