Determining and publishing changed information from data sources to data consumers

A computer program product comprising a non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code when executed by at least one processing device causes the at least one processing device to perform steps of:

• performing a polling operation for at least one data source to obtain information for one or more designated topics of interest;
• determining whether the information for a given one of the one or more designated topics of interest obtained during the polling operation comprises changed information;
• responsive to determining that the information for the given designated topic of interest obtained during the polling operation comprises changed information, generating one or more events comprising the changed information;
• and
• publishing the generated one or more events to one or more event streams, the one or more event streams being subscribed to by one or more data consumers;
• wherein the one or more data consumers each comprise one or more devices that are operated by a given entity;
• and
• wherein the at least one data source is at least one of (i) outside a control of the given entity and (ii) not configured for providing one or more notifications to the one or more data consumers in response to the changed information for the given designated topic of interest.

A method comprising:

• performing a polling operation for at least one data source to obtain information for one or more designated topics of interest;
• determining whether the information for a given one of the one or more designated topics of interest obtained during the polling operation comprises changed information;
• responsive to determining that the information for the given designated topic of interest obtained during the polling operation comprises changed information, generating one or more events comprising the changed information;
• and
• publishing the generated one or more events to one or more event streams, the one or more event streams being subscribed to by one or more data consumers;
• wherein the one or more data consumers each comprise one or more devices that are operated by a given entity;
• and
• wherein the at least one data source is at least one of (i) outside a control of the given entity and (ii) not configured for providing one or more notifications to the one or more data consumers in response to the changed information for the given designated topic of interest;
• and
• wherein the method is performed by at least one processing device comprising a processor coupled to a memory.
