Postman Sandbox and System Time Zone Interoperability

Postman utilizes a Node.js-based Sandbox for Pre-request Scripts and Tests, allowing the use of JavaScript Date objects and the bundled moment.js library to handle ISO 8601 conversions and regional offsets. When executing scripts that rely on the local system time for API assertions, there is a potential discrepancy in how the runtime environment resolves th

Does InfluxDB write latency to a single shard degrade predictably under concurrent writers?

I am planning capacity for an InfluxDB deployment where many clients write points that land in the same shard concurrently. My understanding is that writes to one shard contend on the TSM writer lock, so per-point latency should rise with concurrency, but I have not found guidance on whether that degradation is roughly linear, threshold-based, or tied to com

DynamoDB ClientRequestToken 8-hour TTL: handling retries after token expiry

Idempotent write safety beyond the token retention window DynamoDB stores a ClientRequestToken for PutItem, UpdateItem, and DeleteItem operations for up to 8 hours. Within that window, retries with the same token return the original response without re-executing the write. After the token is purged, a retry with the same token executes as a new write, which

Django REST Framework and PostgreSQL: Managing Connection Pool Exhaustion with CONN_MAX_AGE

Persistent Connection Behavior In high-traffic Django REST Framework (DRF) deployments using PostgreSQL, the CONN_MAX_AGE setting determines whether database connections are closed at the end of a request or persisted for future use. While persistent connections reduce the overhead of repeated handshakes, they can lead to connection exhaustion if the number

Tag expression boolean operator filtering diverges between Cucumber 6.x and 7.x

Goal: Clarify whether tag expression boolean operators (and, or, not) are evaluated consistently across Cucumber 6.x and 7.x Gherkin parser versions when applying step filters. Constraints: Tag expression syntax and AST transformation rules differ between major releases, and the --dry-run flag may report step counts that do not align across versions. The off

Grafana data source TLS: limits of CA certificate reloads and DNS caching without restart

Goal I am operating Grafana (assume a current LTS release) with several provisioned data sources (Prometheus and Loki) that use TLS with a custom CA supplied via tls_ca . I want to understand the operational limits of certificate validation and DNS resolution for these connections, specifically around rotation and failover scenarios. Constraints and uncertai

Neovim Core ↔ Lua Runtime: Synchronization of Terminal Output

Neovim Core ↔ Lua Runtime: Synchronization of Terminal Output The goal is to understand how the core C implementation of Neovim’s terminal emulator coordinates with the Lua runtime when a terminal process emits rapid output. In practice, high‑frequency writes can block the main event loop, causing the editor to freeze or lose keystrokes. The current design r
