OrientDB Interview Questions and Answers
Experienced / Expert level questions & answers
Ques 1. Explain sharding in OrientDB.
Sharding in OrientDB involves distributing data across multiple servers to improve scalability and performance.
Ques 2. How does OrientDB handle distributed transactions?
OrientDB supports distributed transactions through the use of the Paxos algorithm, ensuring consistency across multiple nodes in a distributed environment.
Ques 3. How does OrientDB support geospatial indexing?
OrientDB provides spatial indexes for geospatial data, allowing efficient querying and analysis of data based on geographic locations.
Ques 4. What is the purpose of the OrientDB Object Graph Mapper (OGM)?
The OrientDB Object Graph Mapper is a library that simplifies the interaction between Java applications and OrientDB databases by providing an object-relational mapping (ORM) layer.
Ques 5. What is the purpose of the OrientDB Distributed Configuration?
The OrientDB Distributed Configuration allows users to configure and manage distributed deployments, specifying parameters such as cluster size, quorum, and node roles.
Ques 6. Explain the concept of database sharding in OrientDB.
Database sharding in OrientDB involves partitioning data across multiple servers to distribute the workload and improve scalability. Each shard handles a subset of the data.
Ques 7. How does OrientDB support data replication and high availability?
OrientDB supports data replication through mechanisms like automatic clustering and synchronous replication, ensuring high availability and fault tolerance.
