Replaces the separate SQL-only /query and text-only /search endpoints
with one pipe-syntax query language (plus raw SQL escape hatch) that
compiles to a single IR and execution plan across both backends, so a
query like `message:"connection refused" | stats count by host` runs
as one request instead of two disjoint tools.
- api/internal/querylang: lexer -> ast -> parser -> ir -> planner ->
executor, each layer independently tested.
- Execution generalizes Phase 1's proven Tantivy-prefilter pattern
into a 4-way routing table (pure ClickHouse / text-only / text +
aggregation / raw SQL passthrough).
- Unified web query page and `sentryctl query`, both hitting the same
POST /query endpoint.
- Benchmarked against a real 1,022,000-row dataset
(hack/benchmark-fixture); caught and fixed a real bug where the
Tantivy prefilter cap (10,000) produced an IN-clause exceeding
ClickHouse's default max_query_size -- lowered to 5,000, documented
in docs/query-language-design.md and docs/phase-2-runbook.md.
- docs/query-language-reference.md: customer-facing syntax reference.
End-to-end log pipeline for Linux hosts, per /docs/architecture.md:
- proto: shared gRPC contract (agent <-> ingest), Go bindings checked in
- agent: Rust, musl-targeted, journald/file sourcing, RFC5424 parser,
mTLS gRPC client, no required config for the common case
- ingest: Go, single binary with --mode server|consumer|all; gRPC front
end forwards to Redpanda unchanged, consumer normalizes and
batch-writes to ClickHouse with at-least-once delivery
- storage: ClickHouse schema + a plain SQL-file migration runner
- api: minimal SELECT-only query endpoint, plain REST (not gRPC+gateway
yet -- see api/README.md)
- web: SvelteKit static SPA, one query page
- transport: Redpanda compose + topic provisioning
- cli: sentryctl ping stub
- hack/dev-certs: throwaway CA + cert generation for local mTLS
- root docker-compose.yml + docs/phase-0-runbook.md tie it together
Not yet run end-to-end against real Docker/ClickHouse/Redpanda -- see the
runbook's caveats section before relying on this working as-is.
