DuckDB – in-process SQL OLAP database management system
Quite a while ago, when duckdb was just a duckling, I wrote an R package that supported direct manipulation of R dataframes using SQL.[1] duckdb was the engine for this.
The approach was never as fast as data.table but did approach the speed of dplyr for more complex queries.
Life had other things in store for me and I haven’t touched this library for a while now.
At the time there was no Julia connector for duckdb, but now that there is, I’d like to try this approach in that language.

ClickHouse as an alternative to Elasticsearch for log storage and analysis
Yeah, I agree sqldf is quite slow. Fair point.
As you've seen, duckdb registers an "R data frame as a virtual table." I'm not sure what they mean by "yet" either.
Of course it is possible to write an R dataframe to an on-disk duckdb table, if that's what you want to do.
There are some simple benchmarks on the bottom of the duckdf README[1]. Essentially I found for basic SQL SELECT queries, dplyr is quicker, but for much more complex queries, the duckdf/duckdb combination performs better.
If you really want speed of course, just use data.table.

Julia 1.6: what has changed since Julia 1.0?
That's a really good point that I'd not really thought about. I'd never really considered the difference between calling just functions versus macros.
Thinking about Query.jl and DataFramesMeta.jl, and I am for sure not an expert in either, I can't specifically speak to your `head` example, but other base functions can be combined with macros. For example, see the LINQ examples from DataFramesMeta.jl[1] where `mean` is being used. Or again the LINQ style examples in Query.jl[2], where `descending` is used in the first example, or `length` later in the Grouping examples.
Is that the kind of thing you meant?
For whatever reason, with the way my brain is wired, the LINQ style of query just works for me. I have never directly used LINQ, but do have some SQL experience. In fact, I wrote some dinky little wrapper functions[3] around duckdb[4] so I could directly query R dataframes and datatables with SQL using that backend, rather than sqldf[5].

ClickHouse as an alternative to Elasticsearch for log storage and analysis
It is good. I can't find any CDC for Postgres for the incremental sync. And so I had to use the bulk update/sync and that causes performance issues occasionally. Also, some Algolia features are not available yet https://github.com/meilisearch/instant-meilisearch/issues/21...
What are some alternatives?
tidyquery - Query R data frames with SQL
loki - Like Prometheus, but for logs.
Typesense - Open Source alternative to Algolia + Pinecone and an Easier-to-Use alternative to ElasticSearch ⚡ 🔍 ✨ Fast, typo tolerant, in-memory fuzzy Search Engine for building delightful search experiences
Apache Solr - Apache Lucene and Solr open-source search software
julia - The Julia Programming Language
ClickHouse - ClickHouse® is a free analytics DBMS for big data
