Thanks @SuLea-IT for the contribution! This significantly reduces memory usage (53% lower RSS peak) by avoiding per-row HashMap materialization and cloning. Appreciate the detailed memory audit docs as well.
Turso is a distributed SQLite database built on libSQL, offering HTTP-based
connectivity with auth token authentication. This change adds full support:
- New DatabaseType::Turso and PoolKind::Turso variants
- TursoClient driver using libSQL HTTP pipeline API (/v2/pipeline)
- Bearer token auth via password or url_params (auth_token=)
- Multi-statement batch pipeline for transactional integrity
- Standalone BEGIN/COMMIT/ROLLBACK treated as no-ops (pipeline is auto-commit)
- Full metadata support: tables, columns, indexes, foreign keys, triggers, DDL
- Frontend: connection form, SQL completion (SQLite syntax), capability sets
- Built-in databases (SQLite/Turso/DuckDB/RQLite/Access) placed first in selector
- Unit tests (15) + integration tests against live libsql-server (12)
- Single connection pool, skips TCP probe
Closes#948
Replace per-driver proxy bypass logic with a shared http_client_builder()
that always calls .no_proxy(). Previously ES and rqlite only bypassed for
localhost, causing remote connections to be routed through system proxy
(like Clash Verge) and failing — the same issue #922 fixed for ClickHouse.
MongoDB shell syntax like db.collection.find({}) was incorrectly
parsed as SQL, causing a "sql parser error" diagnostic in the editor.
Added MongoDB guards in shouldRunSqlSemanticDiagnostics and
refreshSemanticDiagnostics, matching existing Elasticsearch logic.
Also fix a pre-existing TiDB cloud URL param ordering test failure.
Extract field names and values from hash-type arrays in
redis_search_value_text() instead of serializing the whole JSON,
so that value search can match individual hash fields and values.
* feat(elasticsearch): translate SELECT * WHERE to ES DSL in-process
`SELECT *` with clauses our hand-written parser doesn't cover (WHERE, IN, BETWEEN, LIKE, IS NULL, ...) is now parsed with sqlparser-rs and translated to a /_search body locally — we no longer hand it off to ES's _sql endpoint.
Why: _sql refuses several common shapes — LIKE on a text field with no .keyword sub-field (the typical filebeat / log-shipper mapping), and SELECT * over docs containing an array field like host.ip. Both translate cleanly to raw DSL. Going through _sql/translate doesn't help either — that lives in the same ES SQL engine and inherits the same restrictions.
Translation:
- field = 'v' → term
- field LIKE 'prefix%' → prefix (optimised)
- field LIKE '%x%' → wildcard, case_insensitive
- field IN ('a','b') → terms
- field BETWEEN a AND b → range gte/lte
- field >/<>=/<= → range
- field IS NULL / IS NOT NULL → bool.must_not.exists / exists
- A AND B AND C → flattened bool.must
- A OR B → bool.should, minimum_should_match: 1
- NOT A → bool.must_not
- ORDER BY f ASC|DESC → sort
- LIMIT N OFFSET M → size / from
SQL LIKE patterns: % → *, _ → ?, backslash escapes preserved, user-written * / ? in patterns escaped back to literals.
Input runs through the existing adapt_elasticsearch_sql_query first so hyphenated indices (filebeat-7.17.1-…) and @timestamp-style identifiers reach sqlparser as double-quoted identifiers.
Also: 0-hit _search bodies now surface as an empty grid (with an _id column placeholder) instead of falling back to the raw status/response JSON view — `.filter(|h| !h.is_empty())` was masking the empty-result case.
Adds docs/screenshot-es-sql-where.png demonstrating SELECT * with WHERE log.offset = N on a long field — would 400 through _sql, works through the in-process translator.
Follows up on #874.
* chore(test): fill ConnectionConfig::idle_timeout_secs in test fixtures
After the new pub idle_timeout_secs: u64 field was added to ConnectionConfig, 11 #[cfg(test)] / tests fixture constructors still built the struct without it, so `cargo test --workspace --locked` and `cargo clippy --all-targets` would fail with E0063 against the test profile. `cargo check` alone passed because the lib path doesn't compile tests.
Filled in with default_idle_timeout_secs() (matches the field's own #[serde(default = …)]) so future bumps to the default flow through automatically.
