I actually don’t hate the new Google Health app, but it could still use some work. Here are my highlights after testing the revamped Fitbit app, and how I think Google can improve

The Google Health app has been redesigned from its previous identity as Fitbit and launched alongside the Fitbit Air. It features daily run recommendations enhanced by AI, but lacks the ability to send non-running workouts to the Pixel Watch. The workout interface is user-friendly, but the Pixel Watch cannot automatically count reps or sets. The categorization of workouts as "suggestions" in the Fitness tab is less definitive than before, though Google plans to reintroduce structured schedules later this year. The app provides motivational messages based on user activity and sleep metrics, allowing for flexible goal adjustments. The food logging feature allows users to log meals through descriptions or photos, but nutritional accuracy is inconsistent. The app syncs with MyFitnessPal for better meal logging. Additionally, users can link medical records to access health information in one place, although the presentation of historical data can be overwhelming. Google Health is actively working on updates based on user feedback, though some features, like sleep profiles, are not currently available.

Databricks Syncs Postgres to Lakehouse Natively

Databricks has introduced Native Lakehouse Sync, currently in public preview, which enables direct replication of data from Lakebase Postgres into Unity Catalog managed tables, simplifying data transfer without traditional pipeline complexities. This feature operates natively within Lakebase, utilizing its Write-Ahead-Log (WAL) and requiring minimal setup time. It does not negatively impact Postgres performance or incur additional costs, and schema changes are automatically propagated. Native Lakehouse Sync supports agent-first development by scaling down when idle and integrating monitoring functions. Data transferred to Unity Catalog is immediately accessible for AI-native analytics and benefits from unified governance features. Every data operation is captured as SCD Type 2 history by default, facilitating compliance and audit processes. The setup of Lakebase and activation of sync is quick, allowing existing and future tables to be available in Unity Catalog within a minute.

Why Postgres wants NVMe on the hot path, and S3 everywhere else

Efforts to merge storage roles into a single solution are ongoing, particularly with Amazon S3's durability and cost-effectiveness. In PostgreSQL, achieving a durable commit requires flushing the Write-Ahead Log (WAL) before signaling transaction completion, which can take tens of microseconds on high-performance NVMe drives but extend to milliseconds on slower storage. This latency impacts Online Transaction Processing (OLTP) systems and user response times. Benchmark studies show that systems with faster local storage outperform those with slower alternatives as workloads exceed memory capacity. The fsync operation in PostgreSQL is a commitment rather than a simple write, with enterprise-grade SSDs performing better due to power-loss protection. Read operations also face challenges, as PostgreSQL's need for small, latency-sensitive reads conflicts with S3's design for larger, higher-latency requests. As the working set exceeds memory, storage latency becomes a critical performance factor. Modern managed PostgreSQL systems typically do not place object storage in the critical commit path, instead maintaining a fast log or cache close to the database while relegating colder data to remote storage. Recent PostgreSQL developments, such as asynchronous I/O support in version 18, aim to leverage fast storage more effectively. S3 is valuable for tasks like WAL archiving and backups, but these should be kept separate from the commit path to avoid resource contention. The solution involves using both NVMe and S3, with fast storage managing commits and cache misses, while object storage handles archives and backups. PostgreSQL performs best when hot and cold storage functions are clearly delineated.

Database Branching in Postgres: Git-Style Workflows with Databricks Lakebase

Database branching is a modern approach that addresses the limitations of traditional database management in development workflows. Unlike conventional database copies, which require significant time and resources to duplicate data and schema, database branching allows for the creation of isolated environments that share the same underlying storage. This method utilizes a copy-on-write mechanism, enabling branches to be created in seconds regardless of database size, with storage costs tied only to the changes made. Key features of database branching include: - Branch creation time: Seconds, constant regardless of database size. - Storage cost: Proportional to changes only, not the total data size. - Isolation: Each branch has its own Postgres connection string and compute endpoint. - Automatic scaling: Idle branches can scale compute to zero, incurring costs only when active. The architecture supporting this approach separates compute from storage, allowing multiple branches to reference the same data without conflict. This design facilitates time travel capabilities, enabling branches to be created from any point in the past for instant recovery and inspection. Database branching unlocks new workflows, such as: - One branch per developer, providing isolated environments for each engineer. - One branch per pull request, automating branch creation and deletion tied to PRs. - One branch per test run, provisioning fresh databases for each CI pipeline execution. - Instant recovery from any point in time within a designated restore window. - Ephemeral environments for AI agents, allowing programmatic database provisioning. Databricks Lakebase offers this database branching capability, transforming the database from a bottleneck into a streamlined component of the development process.
