The built-in Aspire dashboard provides a way to browse logs,

This post describes our approach to implementing a disk-backed hashmap in Rust for indexing high-cardinality predicates in our diagnostics product, Seq. If you've ever wondered how a hashmap works, or what makes a disk-backed datastructure different from an in-memory one, you might find it interesting.

Seq is a

TL;DR: With Seq 2024.3, Seq gains user-defined high-cardinality indexes, its first new index type since the introduction of signal indexes back in 2018! If you're eager to skip to the binaries and dig around for yourself, you can get MSIs at https://datalust.co/download, or
