🌈 Improvements

Log Search performance trace

Introduces comprehensive progress tracking and logging for search operations in Meilisearch. It adds detailed timing information for each step of the search process, enabling better observability and performance analysis.

Extract document operations from payloads in parallel

We accelerate document indexing by processing a large number of tasks in batches or a large number of records in parallel. We expedited the preparation of the payloads by extracting the various changes and assigning internal IDs in parallel. We achieved a 7x speedup on a four-million-document insertion using four CPUs, and the performance scales with the number of CPUs.

The indexedDocuments field in tasks using skipCreation no longer precisely reflects the number of document operations performed, specifically for POST and PUT operations. This count may be higher than the actual number of operations, but it doesn't affect the computation; only the reported count is impacted. We prioritize speed over perfect accuracy here, and the documents are still correctly indexed as before.

🐛 Bug fixes

Vector sort: Bucket documents with same similarity

Fixed vector sort bucketing so documents with identical similarity scores are grouped together, ensuring subsequent ranking rules are applied correctly.

Properly Delete Documents from FID-Based Databases

Fixes a bug where changing searchableAttributes from ["*"] to a subset of fields left orphaned data in fid-based databases, causing corruption and warnings during search.

Rebuild the graph links when dumpless-upgrading

Bumps hannoy to v0.1.3-nested-rtxns, which fixes graph-related recall issues and adds a method to rebuild graph links to recover previously malformed graphs. Also fixes a minor issue in the dumpless upgrade flow where the upgrade description was not displayed correctly and related operations were not properly associated with the upgrade.

9.3.0

QuestDB 9.3.0

QuestDB 9.3.0 is now available, bringing a new wave of query expressiveness and usability improvements across the engine and the Web Console. This release introduces window joins for precise time-based analytics, database views for cleaner query composition, AI-assisted workflows in the console, and the new PIVOT keyword for effortless wide-schema aggregations.

New features

Window joins for time-based aggregation

QuestDB now supports WINDOW JOIN, a new join syntax designed specifically for time-based analytics.

WINDOW JOIN allows each row from a primary table to be joined with a time window of rows from another table, with aggregations computed over the matching rows. This makes short-horizon analytics—such as correlating trades with nearby market prices—both expressive and efficient.

SELECT
  t.*,
  avg(p.bid) AS avg_bid,
  avg(p.ask) AS avg_ask
FROM trades t
WINDOW JOIN prices p
  ON p.sym = t.sym
  RANGE BETWEEN 1 second PRECEDING
        AND 1 second FOLLOWING
  INCLUDE PREVAILING;

In this example, each row from trades is joined with all rows from prices that share the same symbol and fall within the [-1s, +1s] interval (inclusive). Aggregations are then calculated over the joined rows.

This syntax avoids complex subqueries and makes time-windowed joins explicit, readable, and performant.

Database views

QuestDB 9.3.0 adds support for database views.

Views are virtual tables defined by a SELECT statement. They do not persist data on disk. Instead, the underlying query is executed as a subquery each time the view is referenced.

This allows you to encapsulate complex logic, reuse queries across applications, and expose stable schemas without duplicating or materialising data.

CREATE VIEW latest_trades AS
SELECT
  symbol,
  side,
  last(price) AS price,
  last(timestamp) AS ts
FROM trades
GROUP BY symbol, side;

Views can be queried just like tables, while always reflecting the latest data from their source tables.

AI-assisted workflows in the Web Console

The QuestDB Web Console now includes LLM-powered assistance, available on an opt-in basis using your own API key.

Once enabled, the console can:

  • Auto-describe table schemas and column semantics
  • Annotate sample rows with plain-language context
  • Walk through query execution plans, highlighting joins, filters, and index usage

This makes it easier to understand both what a query does and how it executes—directly where you write SQL.

PIVOT: wide-schema aggregations

This release introduces the new PIVOT keyword.

PIVOT is a specialised form of GROUP BY that transforms rows into columns, helping you move from a narrow schema to a wide one in a single query.

Consider the following trades table:

CREATE TABLE trades (
  symbol SYMBOL CAPACITY 256 CACHE,
  side   SYMBOL CAPACITY 256 CACHE,
  price  DOUBLE,
  amount DOUBLE,
  timestamp TIMESTAMP
) timestamp(timestamp) PARTITION BY DAY WAL;

A traditional aggregation might look like this:

SELECT side, symbol, last(price) AS price
FROM trades
WHERE symbol IN ('BTC-USD', 'ETH-USD')
ORDER BY side, symbol;

Resulting in a narrow result set.

With PIVOT, the same logic can be expressed as a wide schema:

trades
PIVOT (
  last(price)
  FOR symbol IN ('BTC-USD', 'ETH-USD')
  GROUP BY side
  ORDER BY side
);

PIVOT performs a combined filter and aggregation, mapping values directly into columns. This is particularly useful for reporting, dashboards, and downstream systems that prefer column-oriented outputs.
