What is QuestDB?

QuestDB 10.0 collapses ingest and egress into one binary protocol, then aims at agent-run notebooks.

QuestDB's feed mixes release notes, engineering deep dives and customer stories, and the through-line for the past month has been QWP — its own binary columnar wire protocol. It shipped in 10.0, was benchmarked against InfluxDB Line Protocol on ingestion and against ClickHouse and TimescaleDB on Arrow reads, and now has a standalone explainer covering bidirectional dataframe transfer and built-in failover. Between the protocol posts sit JIT compiler internals and production references from banks and exchanges.

What is ralger?

ralger stopped scraping only web pages and started scraping the files on them.

ralger is a scraping package that wraps rvest behind task-named functions — titles_scrap(), table_scrap(), images_scrap() and so on — aimed at users who want data out of a page without writing selector logic. After four years of quiet it returned in 2.3.0 with a different kind of function: readers for PDF, XLS, XLSX and CSV files, plus comment extraction.

QuestDB vs ralger: editorial side-by-side

Q
QuestDB
DEVOPS
6.3

QuestDB 10.0 collapses ingest and egress into one binary protocol, then aims at agent-run notebooks.

◆ Current state

QuestDB's feed mixes release notes, engineering deep dives and customer stories, and the through-line for the past month has been QWP — its own binary columnar wire protocol. It shipped in 10.0, was benchmarked against InfluxDB Line Protocol on ingestion and against ClickHouse and TimescaleDB on Arrow reads, and now has a standalone explainer covering bidirectional dataframe transfer and built-in failover. Between the protocol posts sit JIT compiler internals and production references from banks and exchanges.

◆ Where it's heading

The protocol work is the thread that matters. QuestDB has been positioning against InfluxDB Line Protocol on ingestion throughput for a while, and 10.0 turned that from a benchmark argument into the default path both in and out of the database. The follow-up posts are consolidation rather than new capability: the same protocol re-explained for a different reader each time, which is what a project does when it needs an ecosystem to adopt a format. Live views and agent-driven notebooks remain the less-proven half of the release.

◆ Prediction

Expect client libraries and third-party connectors to be the next visible work, since a proprietary wire protocol is only worth its switching cost once the dataframe tools speak it. Whether live views leave beta is not something these entries settle.

0.0

ralger stopped scraping only web pages and started scraping the files on them.

◆ Current state

ralger is a scraping package that wraps rvest behind task-named functions — titles_scrap(), table_scrap(), images_scrap() and so on — aimed at users who want data out of a page without writing selector logic. After four years of quiet it returned in 2.3.0 with a different kind of function: readers for PDF, XLS, XLSX and CSV files, plus comment extraction.

◆ Where it's heading

The earlier arc was about making HTML scraping survive contact with the real web — wrapping every function in tryCatch so a dead link or missing connection returns NA with a message rather than an error, adding case-sensitivity control, widening heading extraction to h3. The 2.3.0 additions change the target rather than the robustness: the unit of interest becomes the document a page links to, not the page itself.

◆ Prediction

If the file readers follow the pattern the image functions set, expect preview-and-batch companions next — images_scrap() arrived alongside images_preview() for exactly that reason. The four-year gap before this release makes timing unpredictable.
