dataaaaa!

Replicate DynamoDB to Apache Iceberg on Amazon S3 Tables via Glue zero-ETL without impacting operational traffic. An AWS Lambda function embedding DuckDB executes fast vectorized SQL directly against S3 Tables metadata and Parquet files, returning JSON query results serverlessly.

Snowflake introduced data lineage for streams, enhancing visibility into CDC pipelines. This update helps data engineers track pipeline dependencies and schema transformations across change tracking objects directly in the data platform.

Bruin orchestrates near-real-time fraud monitoring using an append-only ClickHouse MergeTree log fed by PostgreSQL change capture. It aggregates events into minute, hour, and daily rollups, applying interval modifiers to cleanly restate late-arriving payment statuses without full recomputations.

WalShadow enables sub-second Postgres replication to ClickHouse by directly consuming physical WAL streams instead of using logical replication slots. It decodes WAL off-host and writes native blocks to ClickHouse, hitting 200 ms latency and 289K rows/sec in benchmarks.

Selecting CDC tools requires evaluating capture methods, schema evolution, and recovery. Log-based CDC reads transaction logs like WAL or binlog, reducing source database load and latency compared to polling tables.

Filament provides pluggable data replication across sources and sinks via full, incremental, or CDC pipelines. It features bounded batching, verification on both sides of a write, and durable checkpoints using PostgreSQL and NATS JetStream. It can run embedded in Go or deploy to Kubernetes via Helm.

ClickHouse Managed Postgres is now in Private Preview on GCP. The service pairs an NVMe-backed OLTP engine with ClickHouse OLAP, featuring native CDC replication and a unified query layer via pg_clickhouse to prevent cross-cloud egress and simplify pipelines.

ClickHouse Managed Postgres pairs NVMe-backed Postgres for OLTP with ClickHouse for real-time analytics. Its onboarding streamlines loading data, configuring CDC ClickPipes for managed replication, and querying synchronized tables across both engines.

QuintoAndar unified its CDP on ClickHouse Cloud to process 900M monthly events and serve 300M API requests. By replacing a Lambda architecture and using ClickHouse Managed Postgres as an interface, they made real-time analytical data accessible to tools requiring Postgres compatibility.

DuckDB v2.0 introduces four JSON functions to optimize state reconciliation and CDC pipelines. Tools like jsonmergepatchdiff and jsondeep_merge compute minimal RFC 7396 diffs and merge payloads in SQL without external scripts.

CDC does not eliminate dual-writes; it merely shifts them downstream. Updating targets and committing pipeline offsets are independent, non-transactional acts. Without idempotent receivers, dual-write failure modes persist.

Snowflake announced the general availability of the Openflow Connector for SQL Server (CDC). This update enables automated change data capture pipelines from SQL Server into Snowflake for real-time data engineering workflows.

Healthcare AI requires real-time, complete data. Legacy ETL delays AI adoption with rigid pipelines. Fivetran enables modern ELT by providing automated schema handling and continuous change data capture. Fivetran pipelines are configured in minutes and run themselves.

Data replication tools automate continuous data movement from sources like SQL databases or SaaS apps to target warehouses. Methods include CDC-based transactional replication and low-latency streaming.

Modern data engineering is moving away from all-in-one platforms toward best-of-breed tools centered on a control plane that handles orchestration, observability, and metadata. The biggest missing piece in all of this? An enterprise orchestrator.

Build end-to-end data pipelines using AI agents that write specifications and handle operations. An agent constructed a Postgres CDC to Snowflake pipeline with Estuary and Orchestra in under an hour, using OpenMetrics endpoints to gate downstream dbt runs on real-time task health.

Choosing a database CDC tool depends on latency needs and architecture complexity. Log-based tools like Debezium capture every change via transaction logs, while query-based incremental loads using timestamp keys offer a simpler approach. Most teams reach for streaming CDC before they need it.

apitap-lib is a Rust transfer engine that streams tables between databases using native wire formats like binary COPY in bounded memory. It features Python bindings and achieves high throughput on small compute instances. It moves data the way the databases themselves would.

Accessing mainframe IBM Db2 on z/OS data via log-based change data capture replaces costly nightly batch queries with continuous syncs. Shift up to 60 percent of processing to zIIP specialty engines to cut CPU costs. "Fivetran reads the log and captures only what's changed since the last sync."

Choose an incremental data loading strategy based on how the source changes. Use full refresh when rebuilding is cheap, append for immutable rows, merge for keys and reliable updates, delete+insert or time_interval for complete groups, and SCD2 for historical versions.

Replicating databases like Postgres or MySQL to Snowflake requires efficient bulk staging and incremental loads. The open-source ingestr CLI simplifies this by using Snowflake native bulk loading and merge strategies with simple commands.

A global survey shows 85 percent of ERP professionals believe stale data causes incorrect decisions. Log-based change data capture enables real-time data movement with minimal impact on source databases. ETL jobs that took days can run in under an hour.

Snowflake announced Postgres CDC mirroring to automate ingestion and landed Snowflake DataStream, a Kafka-compatible endpoint streaming directly into native or Iceberg tables. OpenFlow also went headless, letting data engineers build ingestion pipelines programmatically via agentic code.

ClickHouse achieved the AWS SMB Competency, validating its expertise in real-time analytics for SMBs. ClickHouse Cloud is built for teams in that position. The fully managed service uses ClickPipes CDC to replicate PostgreSQL data, separating compute workloads to optimize cost and performance.
