Greenplum HD alternatives
Greenplum HD allows you to build a scalable data warehouse system that can hold very large amounts of data, query it at high speed, and run interactive reports on it. You can consider this as a hybrid database solution, and this approach provides a unified view of the data that simplifies analysis and aggregation. It makes use of shared disk and caching technology to improve performance. The solution can handle petabyte-scale levels of data workloads and scales interactive analytics to large datasets without slowing sown performance output.
It also has sophisticated multi-tier security mechanisms to protect data from accidental or malicious loss. The storage subsystem uses array-based RAID levels for efficient access to disks. Moreover, the indexing is accomplished by extending standard PostgreSQL arrays with custom logic to support large databases. The metadata is stored in tables, and each row stores both the raw data and its semantic meaning. All in all, Greenplum HD is a great tool that you can consider among its alternatives.
