What is gtfsio?
gtfsio's job is absorbing the ways real transit feeds violate their own specification.
A low-level R package for reading and writing GTFS transit feeds, deliberately scoped to I/O with the analysis left to packages built on top of it such as gtfstools. Releases are roughly annual. Almost every entry is a fix for a feed that does not match what the specification implies: files without a .zip extension, non-text files inside the archive, subdirectories, blank CSV lines, 64-bit integers in the first row.
What is Tigris?
Tigris keeps publishing its architecture, and the newest post opens up the storage engine itself.
This feed is Tigris's engineering blog, and it alternates between protocol critique and descriptions of how the product answers it. The most recent post opens the internals: how Tigris composes ACID metadata, global placement, caching, replication, and background work on FoundationDB into a multi-region object store. Before it came the Recycle Bin — deletion of objects and buckets on top of immutable storage in an active-active geo-replicated database — plus two posts dissecting SigV4 and presigned URLs, and one on agent-native onboarding through tigris init --agent.

gtfsio
0.0DEVOPS
gtfsio's job is absorbing the ways real transit feeds violate their own specification.
◆ Current state
A low-level R package for reading and writing GTFS transit feeds, deliberately scoped to I/O with the analysis left to packages built on top of it such as gtfstools. Releases are roughly annual. Almost every entry is a fix for a feed that does not match what the specification implies: files without a .zip extension, non-text files inside the archive, subdirectories, blank CSV lines, 64-bit integers in the first row.
◆ Where it's heading
The package has stabilised into a maintenance rhythm around two axes. One is defensive reading — each release absorbs another malformed-feed case and turns a hard failure into a warning plus a sensible default. The other is keeping the bundled specification current, which moved from a get_gtfs_standard() function to a gtfs_reference dataset that is simply refreshed, most recently to the April 2026 revision. The 1.0.0 introduction of custom-classed gtfsio_error conditions was the one structural decision, letting downstream packages catch specific failures rather than parsing message strings.
◆ Prediction
Expect continued annual releases pairing a refreshed gtfs_reference with whatever new feed malformation has been reported; nothing here suggests the package will expand past its I/O remit.
Tigris
5.0DEVOPS
Tigris keeps publishing its architecture, and the newest post opens up the storage engine itself.
◆ Current state
This feed is Tigris's engineering blog, and it alternates between protocol critique and descriptions of how the product answers it. The most recent post opens the internals: how Tigris composes ACID metadata, global placement, caching, replication, and background work on FoundationDB into a multi-region object store. Before it came the Recycle Bin — deletion of objects and buckets on top of immutable storage in an active-active geo-replicated database — plus two posts dissecting SigV4 and presigned URLs, and one on agent-native onboarding through tigris init --agent.
◆ Where it's heading
The writing is doing product work. Each protocol post establishes a problem — SigV4's canonicalization and clock skew, presigned URLs as deliberate replay attacks, S3 egress pricing on ClickHouse restores — and positions Tigris behavior as the answer, which makes the blog a migration funnel rather than a changelog. The architecture post is a different move: publishing the FoundationDB composition is a credibility play aimed at buyers who need to believe a newer object store can hold multi-region data.
◆ Prediction
Expect the protocol-critique-then-Tigris-answer format to continue, with the egress-cost framing recurring as the clearest paid migration path. Feature announcements will likely stay embedded in essays rather than appearing as release notes.
