- Sep 22, 2026 Multipart Upload: Choosing a Part Size That Survives a Retry Parts are immutable commit units. The 5 MiB floor, 10,000-part ceiling, and per-part checksums turn part size into a decision about retry cost and memory. cloud infrastructure
- Jul 9, 2026 How a Table Format Replaces Directory Listing with a Metadata Tree Why a lakehouse table is defined by a chain of metadata files rather than by the contents of a prefix, and what each level of that chain costs a reader to open. data engineering
- Jan 2, 2026 Byte-Range Reads: Partial Responses, Alignment, and Parallel Fetch A Range header turns one object into many concurrent reads. What the 206 response guarantees, why alignment matters for throughput, and where range requests break. cloud infrastructure
- Oct 2, 2025 The Flat Keyspace: What an Object Store Does and Does Not Provide Object storage maps opaque keys to immutable byte strings. The operations it omits, including rename, append, and multi-key atomicity, shape every design built on top of it. cloud infrastructure
- Aug 26, 2025 Conditional Writes: Building a Lock Out of Single-Key Compare-and-Set A precondition on an object write gives one writer a win and the rest a 412. How to use that primitive for leases, exactly-once publication, and safe fan-out. cloud infrastructure
- Mar 31, 2025 What a Successful Write Guarantees: Durability and Read-After-Write Consistency A 200 response means the bytes survive disk failure, not that every reader sees them yet. How replication, quorums, and listing indexes set the visibility rules. cloud infrastructure
- Jan 17, 2023 Storage Lifecycle Transitions and Minimum Durations How a lifecycle rule becomes a charge: the transition request, the per-object metadata charge in each class, minimum storage durations, and early-deletion fees. cloud infrastructure
- May 21, 2022 Versioning, Delete Markers, and What a Delete Actually Removes Enabling versioning turns overwrite into append and delete into a placeholder. The state machine has three modes, and the suspended mode is where most surprises live. cloud infrastructure
