Hierarchical object tagging framework

A system for implementing an object tagging framework comprising:

• one or more processors;
• and
• a memory having instructions stored therein, when executed by the one or more processors, cause the system to perform operations comprising:
• performing, using a tag controller of a distributed database, operations comprising:
• receiving, from a first client device via a network, an association command, a tag name, and a target object identifier;
• creating a current tag based on the tag name;
• determining from among a plurality of target objects across the distributed database, one or more target objects associated with the target object identifier, the one or more target objects including respective tag values;
• associating the current tag with each of the one or more target objects;
• identifying one or more respective first child objects of the one or more target objects, wherein the one or more target objects and the one or more respective first child objects are related in an entity hierarchy;
• in response to determining that a first child object of the one or more first child objects is tag-unassociated, associating the current tag with the first child object;
• storing the current tag and one or more tag associations of the one or more target objects and the one or more respective first child objects in a central metadata store of the distributed database;
• and
• storing a state of the tag controller in a database management system on a single machine of the distributed database;
• in response to receiving a query including the tag name from a second client device via the network, performing operations comprising:
• finding one or more found target objects and the one or more found first child objects across the distributed database using the tag name and the one or more tag associations stored in the central metadata store of the distributed database;
• generating an output based on the found one or more target objects and found one or more first child objects;
• and
• causing, via the network, the output to be displayed on a display device of the second client device.

A non-transitory computer-readable storage medium including instructions that, when executed by a machine cause the machine to perform operations comprising:

• performing, by a tag controller of a distributed database, operations comprising:
• receiving, from a first client device via a network, an association command, a tag name, and a target object identifier;
• creating a current tag based on the tag name;
• determining from among a plurality of target objects across the distributed database, one or more target objects associated with the target object identifier, the one or more target objects including respective tag values;
• associating the current tag with each of the one or more target objects in the distributed database;
• identifying one or more respective first child objects of the one or more target objects, wherein the one or more target objects and the one or more respective first child objects are related in an entity hierarchy;
• in response to determining that a first child object of the one or more first child objects is tag-unassociated, associating the current tag with the first child object;
• storing the current tag and one or more tag associations of the one or more target objects and the one or more respective first child objects in a central metadata store of the distributed database;
• and
• storing a state of the tag controller in a database management system on a single machine of the distributed database;
• in response to receiving a query including the tag name from a second client device via the network, performing operations comprising:
• finding one or more found target objects and the one or more found first child objects across the distributed database using the tag name and the one or more tag associations stored in the central metadata store of the distributed database;
• generating an output based on the found one or more target objects and found one or more first child objects;
• and
• causing, via the network, the output to be displayed on a display device of the second client device.
