Open source works great for for-profit companies. Take a look at RedHat.

TimescaleDB has not so good performance and on-disk data compression rate comparing to ClickHouse [1]. TimescaleDB is good for cases with relatively small amounts of time series data (e.g. up to a few tens of billions rows) when you already

If you need efficient exporting of any amounts of logs, then take a look at VictoriaLogs - the log management system I work on. It is designed in the way which allows exporting arbitrary number of logs via the standard querying API. See ht

What to use as a centralized system for `keep things "stupid-simple"`? I'd recommend taking a look at VictoriaLogs - the system I work on. It is designed with KISS principle in mind, so it is very easy to setup, operate and u

Scala is overcomplicated esoteric programming language. It is great for obfuscation contests. It is awful for production code, since Scala code lacks maintainability, readability and simplicity properties.

The sync.Map.Range, filepath.Walk and other similar functions with visitor pattern in standard Go packages will remain there forever because of backwards compatibility. This means that new functions must be added to standard Go packages in

Go provides generic types since v1.0 - maps, slices and channels. Go also provides generic functions and operators for working with these types - append, copy, clear, delete. This allows writing clear and efficient code. There is close to z

While vendoring is great, generics is bad addition to Go, since they complicated Go type system too much [1]. This makes typical Go code with generics hard to read and hard to maintain. [1] https://go.dev/blog/type-infe

Iterators and generics go against the original goals of Go - simplicity and productivity. They complicated Go language specification too much without giving back significant benefits. Iterators and generics also encourage writing unnecessar

Batched inserts to LSM-based databases aren't so uncommon. For example, ClickHouse expects batched writes - https://clickhouse.com/docs/en/optimize/bulk-inserts . Of course, it supports asynchronous inse

LSM trees do not need write-ahead log in general case: - When new data arrives, it is converted to SSTable, which is then stored to disk in an atomic manner before returning 'success' to the client, who writes the data. If compute

My advices to new software engineers: - Always think how to simplify the code you write, since simple code is easier to maintain and debug. - Prefer writing dumb code than smart code. Smart code is good for programming contests. Smart code

Software products usually have no publicly available development goals. Probably some of these products have internal development goals, but most of the time these goals are implicit. You can guess these goals by looking at the history of n

It would be great if the README.md contained both versions of the code - without using xtract+iterators and with using xtract+iterators, so readers could compare both versions.

How about allowing users creating pipelines with good old grep, awk, cut, etc., directly in the web UI?

Correct for now. I'm sure LogsQL support will be added into other systems for logs' management over time.

Canonical pipes were invented ~50 years ago by Unix creators. They are successfully used for logs' analysis to this day. Unix pipes have a simple idea - connecting the output of one program to the input of another program. This allows
