Distributed Data Storage System

iServer DataStore is an application that allows you to quickly create a data store from iServer DataStore and associate the data store with iServer. iServer provides an interface to provide this data to clients, and data uploaded by clients can also be stored in the DataStore.

In order to ensure high availability of data storage, multiple DataStores can be used to form a distributed data storage system. You can associate multiple DataStores with one iServer, and configure different types of data storage for each DataStore. It can be:

• Relational Data Store: When you configure a relational data store in the DataStore, a PostgreSQL is automatically created Database, which stores data sets (*.udd, *.udb).
• Binary data storage: Store the data in any format uploaded by the user through the iPortal portal software platform, relying on MongoDB database.
• Slice data storage: Store map tiles data in MongoDB.
• Spatio-temporal data storage: Store spatio-temporal data, stored in Elasticsearch.

The client accesses these data stores through the iServer data catalog services, and then downloads, uploads, and analyzes the data.
