Building a High-Performance Postgres Time Series Stack with Iceberg
I am not sure why Snowflake publishes articles about PostgreSQL, but this is a good introduction to ingesting time-series data in PostgreSQL. They use the following tools:
pg_partman: An extension that automates the creation and maintenance of time partitions for large tables, which improves performance and simplifies maintenance.
pg_lake: An extension designed to bridge Postgres with data lakes (such as S3), allowing you to offload older “cold” time series data to Apache Iceberg while keeping it queryable in Postgres.
pg_incremental: An extension to process append-only Postgres data in incremental batches.
Flexibility is becoming the defining requirement in enterprise infrastructure, especially as businesses outpace traditional IT refresh cycles and VMware customers reassess their platforms amid licensing changes and broader market disruption.
The article’s core argument is that teams no longer want architectures that force trade-offs among cost, performance, and capacity, or that require large-scale hardware replacement just to support a platform change.
Its main example is Cisco FlashStack with Nutanix, launched in January 2026, which combines Cisco UCS compute and networking, Nutanix Cloud Platform, and Pure Storage FlashArray into a modular converged stack. The pitch is essentially “convergence with choice”: keep the operational simplicity of an integrated platform, but allow compute and storage to scale independently rather than tying them together in the classic HCI model.
Why flexibility will define the future of functionality
Two broader infrastructure themes stand out. First, disaggregated architectures are becoming more attractive because they allow enterprises to size resources per workload rather than overprovision entire stacks. Second, standard Ethernet plus NVMe/TCP is presented as a way to reduce dependence on Fibre Channel SANs and simplify operations by moving more storage traffic onto common IP networking.
There is also a clear post-VMware migration angle. The piece points to Gartner’s view that by 2028, 35 per cent of workloads currently on VMware will move elsewhere, and argues that buyers increasingly want migration paths that protect existing hardware investments rather than forcing a rip-and-replace cycle.
The real takeaway is less about one specific product and more about where infrastructure buying criteria are heading: validated stacks, modular scaling, lower migration risk, and more optionality.
