- Add cmd/arc/main.go (was ignored by git) - Add helm/arc chart (was ignored by git) - Remove -tags=duckdb_arrow from Dockerfile (not needed) - Remove CGO_ENABLED=0 and comment from workflow - Simplify build commands
DuckDB requires CGO, so we use Docker buildx for cross-compiling arm64 binaries on the amd64 runner.
- Fix all arc-go URLs to arc (image name, homepage, docs) - Add test-docker job: pulls image, tests /health endpoint - Add test-binary job: runs binary, tests /health endpoint - Update release notes with migration highlights: - 9.47M rec/s MessagePack (125% faster than Python) - Memory stable (no 372MB leak) - Full feature parity checklist - Breaking changes and upgrade guide - Add tests to release job dependencies - Add test status to job summary
- Add throughput badges (9.47M rec/s, 2.88M rows/s) - Add Go version, license, docs, website, Discord badges - Add :latest tag to Docker manifest (GHCR doesn't auto-tag) - Update installation section with Docker, deb, rpm, Helm - Update repo references from arc-go to arc - Update Go version from 1.22 to 1.25
- Replace Docker/QEMU emulation with native GitHub runners - Use ubuntu-24.04-arm for linux-arm64 builds (native ARM runner) - Use ubuntu-latest for linux-amd64 builds - Enable CGO (required for SQLite auth database) - Build time reduced from 30+ minutes to ~2-3 minutes
BuildArch is for noarch packages only. For architecture-specific binaries, use rpmbuild --target instead.
Existing databases created by Python don't have the expires_at column. This adds a migration that runs ALTER TABLE to add the column if missing.
MessagePack sends integers (int8, int16, etc.) when values are whole numbers like 0 or 10. This adds type coercion to float64 for all integer types in float columns. Fixes: "unexpected type in float column 'speed': int8"
- local.go: Retry CreateTemp on ENOENT (directory deleted externally), invalidate cache and recreate directory before retrying - arrow_writer.go: Add float32/float64 cases to int column handler, truncating floats to int64 when schema inferred integer type
When Telegraf pushes columnar msgpack data with evolving schemas (columns appear/disappear between batches), mergeBatches() would fail because it only allocated space for columns where they exist, causing: "panic: arrow/array: mismatch number of rows in column" This fix adds schema-aware buffering that detects when columns change between batches and flushes the buffer before adding new data. This ensures all batches in a buffer have identical schemas. Changes: - Add bufferSchemas map to track column signature per buffer - Add getColumnSignature() helper for schema comparison - Detect schema evolution in writeColumnar() and flush on change - Clean up bufferSchemas on buffer deletion
