Interacting and syncing data with external storage systems in Storm can typically be achieved through the following methods:

Utilize Storm’s Kafka connector: Storm offers a connector for integrating with Kafka, allowing you to send output data from a Storm topology to Kafka, and then read and store or analyze the data from Kafka.
Utilize Storm’s HDFS connector: Storm also offers a connector for integrating with HDFS, allowing the output data of Storm topologies to be written to HDFS and then analyzed or stored data retrieved from HDFS.
Create a custom Bolt or Spout: You can design a custom Bolt or Spout to interact with external storage systems, such as connecting to a database using JDBC or linking to other storage systems using REST APIs.
By utilizing Storm’s Trident API, users can easily interact with external storage systems, such as storing data in external databases or caches through Trident’s State interface.

In general, using the several methods mentioned above, it is possible to interact with external storage systems in Storm and synchronize data, meeting the requirements for real-time data processing and storage.
