Glossary

This glossary introduces common Relyt terminology.

administration and use separation​

This capability separates the administration and use of cloud accounts in Relyt. Only invited users can create sub-accounts on Relyt. Administrators can control who can create sub-accounts in their DW service units and the owner of a sub-account can be the only one who knows the password of the sub-account. This way, administration and use of accounts are separated.

AI-ready Data Cloud​

At its core, an AI-ready Data Cloud is a cloud-based infrastructure designed to seamlessly integrate massive datasets with AI-driven analytics. Unlike traditional data warehouses, which often struggle with scalability and real-time demands, an AI-ready Data Cloud is built from the ground up to handle the complexities of modern AI workloads—think high-concurrency queries, real-time insights, and generative analytics—all while keeping costs in check and reliability sky-high.

DataCloud Technology defines this space with two flagship products: Powerdrill AI Analytics, an autonomous data analytics service, and Relyt, a data-centric cloud foundation. Together, they exemplify how an AI-ready Data Cloud can transform enterprise operations, from frontline decision-making to large-scale data infrastructure.

cloud account​

A cloud account, sometimes simply referred to as an account, is a set of credentials that are used to authenticate a user's access to specific resources. Relyt provides two levels of cloud accounts: main account and sub-account.

cloud FinOps​

An operational framework that aims to unite technology, finance, and business to ensure financial accountability and accelerate business value realization through cloud transformation. Relyt provides the cloud FinOps feature to help you efficiently manage your cloud resources, optimize spending, and ensure that your expenses align with your business objectives.

Data Processing Service (DPS)​

Data Processing Service (DPS) is the compute engine provided by Relyt. It is at the core for data processing and is responsible for running queries and compute tasks. DPS is available in two types: Hybrid DPS and Extreme DPS. You can select the desired type based on your actual needs.

data warehouse service unit (DW service unit)​

A data warehouse service unit (DW service unit or service unit), sometimes referred to as service unit, is the basic deployment unit of Relyt. It is compatible with PostgreSQL protocols and allows connections from PostgreSQL-compatible clients, such as psql. A unified console is also available for users to manage their respective DW service units and manage data resources in each DW service unit, such as creating tables, writing data, loading data, and running queries.

DPS cluster​

A DPS cluster is the normalized form of a collection of CPU, memory, and I/O resources. It is available in two types in accordance with the compute engine it uses, namely Hybrid DPS cluster and Extreme DPS cluster. DPS clusters can be created and scaled on demand, as well as released and suspended if any is idle.

DW user​

A DW user is a user that is created to use a specific group of resources in a given service unit.

Extreme DPS​

The high-speed edition of Data Processing Service (DPS). Extreme DPS exhibits a performance advantage on the order of magnitudes compared to Hybrid DPS in terms of the features supported by both editions, though it offers a smaller set of features.

Hybrid DPS​

The general edition of Data Processing Service (DPS). Hybrid DPS is highly compatible with the SQL functionality of PostgreSQL.

main account​

A main account is the logical representation of an organization and uniquely identifies the organization in Relyt. A main account can invite others to create sub-accounts. By default, a main account is a member of the ACCCOUNTADMIN role. It can be changed to temporarily belong to the SYSTEMADMIN role.

near-data processing (NDP)​

A concept in computer architecture that enables processing computations and tasks near the storage device or memory, rather than moving raw data back to the CPU for processing. The aim of NDP is to reduce data movement and processing latency, thereby improving overall system performance.

observability​

A measure of how well internal states of a system can be inferred from knowledge of its external outputs.

operator-level optimization​

A feature that optimizes utilization of cloud resources at the operator level to improve computation density. Operators are the smallest units of computation in a compute engine. This feature enables efficient use of all resources by optimizing each individual operator, thereby maximizing the potential of the overall system.

Parallel DPS​

A feature that allows groups multiple DPS clusters as a whole to process a single large workload in parallel. The number of grouped DPS clusters is equal to the degree of parallelism (DOP) of the workload. This feature enhances the throughput, flexibility, and scalability of Relyt when processing large and complex workloads.

role-based access control (RBAC)​

An approach to restricting access to authorized users. RBAC uses roles and privileges to implement policy-neutral access control.

single sign-on (SSO)​

An authentication scheme that allows a user to log in using one set of credentials to any of several related yet independent applications. Relyt supports SSO to allow quick integration with third-party authentication services.

subaccount​

A subaccount is a segregated account under the control of a main account. Subaccounts can be created only through invitations of the main account and are tied to the main account. A subaccount can be used to perform specific operations that align with the privileges granted by the assigned role.

system role​

A collection of permissions that can be applied to cloud accounts. System roles are used to simplify permission management and access control.

Relyt provides two system roles which are respectively ACCOUNTADMIN, SYSTEMADMIN. Each cloud account must be assigned to a role. A main account defaults to ACCOUNTADMIN and can be then assigned to SYSTEMADMIN. A subaccount can only be assigned to SYSTEMADMIN. ACCOUNTADMIN can be switched to SYSTEMADMIN.
