N1QL/Data Modeling

Comparing Document-Oriented and Relational Data

In this tutorial we are comapring document-oriented models vs relational-oriented models for data.

Using JSON documents

JSON is a lightweight data-interchange format which is easy to read and change.

Schemaless Data Modeling

When you use documents to represent data, a database schema is optional. The majority of your effort will be creating one or more documents that will represent application data.

JSON Design Choices

Couchbase Server neither enforces nor validates for any particular document structure. Below are the design choices that impact JSON document design.

Phases of Data Modeling

A data modeling exercise consists of logical and physical data modeling phases to describe your entities and relationships and map them to physical containers.

Document Key Design

The most important part of NoSQL database modeling is document keys. There are different patterns when it comes to designing a document key.

Standardized Document Properties

Multiple data sets can share a common bucket in Couchbase. To ensure each data set has isolated keyspaces, it's best practice to include a certain prefixes in your document keys.

Standardization, Optimization, and Resources

Wrapping up our Data Modeling Guide, we talk about standardization and optimization of your documents and modeling and share some resources to help you dive deeper.

Document Optimizations

In any database, every byte of stored data adds up, in this tutorial we go over options and best practices to proactively reduce document sizes.

Schema Versioning

Storing the schema version within the document is a best practice that provides a mechanism to migrate and upgrade models as they change over time. In this tutorial, we illustrate an approach to schema management through code.

Document Revisions

There may be requirements to save multiple revisions of a document within a bucket, this history is maintained by the application. This tutorial is intended to outline one way this can be accomplished.

Understanding Query Workflow and Optimization

Applications submit the N1QL query to one of the available query nodes. The Query node parses and analyzes the query, uses metadata on underlying objects to figure out the optimal execution plan and executes it.

Understanding Index Scans

Query predicate indicates the subset of the data interested. During the query planning phase, we select the indexes to be used for the query.

Identifying the Top Slow Queries

The top slow queries can be identified by querying the system catalog.

Understanding an Explain Plan

The tutorial describes the various attributes you see in an explain plan and how to interpret them.

Understanding Cardinality and Selectivity

Cardinality and selectivity can provide measurable insights into your data set and effectiveness of the index, pointing you to where specific optimizations can be made.

Understanding Covering Indexes and TTLs

When using covering indexes, the N1QL queries are constructed in a way to ensure they do NOT return stale data from your indexes(GSIs).

Tuning Tips and Advice

A collection of tips and advice for you to improve the query performance.

Operators Guide

A guide to all the operators for query optimization.

Observability

Monitoring Operating System

In order to have a solid understanding of overall cluster health, it is important to monitor the operating system and various stats for each node in the cluster.

Monitoring Nodes

This tutorial describes the important metrics and how to monitor them for each node in the cluster.

Monitoring Query Service

This tutorial describes the important metrics and how to monitor them for query service running in the cluster.

Monitoring XDCR

This tutorial describes the important metrics and how to monitor them for cross data center replication (XDCR) operations in the cluster.

Monitoring FTS Service

This tutorial describes the important metrics and how to monitor them for full text service (FTS) running in the cluster.

This tutorial goes over the Couchbase API used to access the alerts from the logs in the server.

Install Prometheus

This tutorial walks you through installation and configuration of Prometheus as a stand alone instance. This should not be installed on each or any node in the Couchbase cluster.

Monitoring Eventing Service

This tutorial describes the important metrics and how to monitor them for eventing service running in the cluster.

Node Exporter Setup

This tutorial is optional step in the Prometheus Integration Learning Path and requires setup on each server that you wish to gather system metrics using Node Exporter.

Process Exporter Setup

This tutorial is optional step in the Prometheus Integration Learning Path and requires setup on each server that you wish to monitor process metrics using Process Exporter.

Couchbase Exporter Setup

This tutorial walks you through installation and configure the Couchbase Exporter and its dependencies. The mode you run Couchbase Exporter in will determine a single instance for each cluster, or an instance for each node in the cluster.

Configure Prometheus

Prometheus is configured through a single YAML file. When configured, Prometheus runs as a service, in this tutorial, we configure Prometheus.

Monitoring Index Service

This tutorial describes the important metrics and how to monitor them for index service running in the cluster.

Configure AlertManager

It's important to know that Prometheus can support multiple AlertManagers for High-Availability by specifying more than one target. For the purpose of this tutorial, we install a single AlertManager on the same server as Prometheus and Grafana.

Install Grafana

This tutorial walks you through installation and configuration of Grafana as a stand alone instance. This should not be installed on each or any node in the Couchbase cluster.

Configure Prometheus Alerts

This tutorial will help you to set up and configure Prometheus Alerts with AlterManager configuration ans creation and configuration of Prometheus rules for alerting.

Configure Grafana

This tutorial will help you add a data source for Grafana for use with Prometheus to give your dashboard different ways of visualizing your data.

Upgrading Services

In the final tutorial of the Prometheues Integration learning path, we will upgrade all of our services installed in our application. This can be used for reference in the future as part of ongoing maintainence of your project.

Monitoring Data Service

This tutorial describes the important metrics and how to monitor them for data service running in the cluster.
