In this blog, we explore how to stream data from YugabyteDB’s Change Data Capture (CDC) feature to Snowflake through Amazon S3.
We’ll use YugabyteDB’s CDC SDK server, an open source project that provides a streaming platform for CDC. We’ll also use Snowpipe to automate data loading to files as soon as they are available in a S3 bucket.
Before getting started,

Change data capture (CDC) captures changes made to data in a database and streams those changes to external processes, applications or other databases. In other words, the CDC process identifies whenever there are changes in a database or a table and records those changes to be processed by other downstream applications.
Debezium Server provides a ready-to-use application that streams change events from a source database to messaging infrastructure like Amazon Kinesis or Google Cloud.

It’s been a while since YugabyteDB came out with Change Data Capture (CDC) using Debezium, an open source distributed platform. You can just fire it up as a plugin for Kafka connect and then it will start publishing all the changes in your database to a Kafka topic.
The Debezium Connector for YugabyteDB CDC is our addition to the list of Debezium connectors. It also provides support for reading changes from a YugabyteDB database.

Kubernetes has become widely adopted in the Fortune 500. Many companies are now using the platform to run stateless and stateful applications on-premises or as hybrid cloud deployments in production. Of course, with any new technology, there are growing pains when running resilient Kubernetes workloads. But most executives and developers agree that the benefits far outweigh the challenges.
Data on the Kubernetes ecosystem is evolving rapidly with the rise of stateful applications. However,

Log aggregation is an integral part of a distributed system. As the name suggests, a distributed system will have multiple processes across multiple machines, and each process will generate a lot of data. Looking at the data in silos is time-consuming and wouldn’t yield important information as the data sets still need to be correlated. But aggregating the logs is a huge productivity booster that helps to transform the raw log data into insightful information.

When building modern web applications, developers often find data modeling and data access to be productivity bottlenecks. Rather than moving towards a schema-less database solution, many find using an ORM (object-relational mapping) tool with SQL to be their preferred option. The Node.js community has long been supportive of the Sequelize ORM, with Prisma being a newer option for those looking to model, migrate, and query their data.
In this blog, we’ll get acquainted with Prisma and how it interfaces with Node.js and YugabyteDB.

Change Data Capture (CDC) is a technique to capture changes in a source database system in real-time. The goal is to stream those changes as events through a data processing pipeline for further processing.
CDC enables many use cases, especially in modern microservices-based architecture that involves a lot of bounded services. It is the de-facto choice for use cases such as search indexes, in-memory data cache, real-time notifications, data sync between sources,

In this blog post, we will stream data to downstream databases leveraging YugabyteDB’s Change Data Capture (CDC) feature introduced in YugabyteDB 2.13. This will publish the changes to Kafka and then stream those changes to databases like MySQL, PostgreSQL, and Elasticsearch.
The diagram below represents how data will flow from YugabyteDB to Kafka and then further to the sink databases.
Specifically,

This post walks through how to send data from YugabyteDB to Elasticsearch using YugabyteDB’s Change Data Capture (CDC) feature.
YugabyteDB CDC is a pull-based approach to CDC introduced in YugabyteDB 2.13 that reports changes from the database’s write-ahead-log (WAL). More specifically, the detailed CDC architecture is mentioned in YugabyteDB’s documentation.
Elasticsearch is a search engine based on the Lucene library. It also provides a distributed,

GORM is an Object Relational Mapping (ORM) library for Golang. ORM converts data between incompatible type systems using object-oriented programming languages. An ORM library is a library that implements this technique and provides an object-oriented layer between relational databases and object-oriented programming languages.
In this blog post, we’ll show you how to:
