It specifies a standardized language-independent columnar memory format -for flat and hierarchical data, organized for efficient analytic operations on -modern hardware. It also provides computational libraries and zero-copy -streaming messaging and inter-process communication. - -### A note about FlightSQL drivers - -Go FlightSQL drivers live in the -[ADBC repository](https://github.com/apache/arrow-adbc/tree/main/go/adbc). -In particular, to use the Golang `database/sql` interface: -```golang -import ( - "database/sql" - _ "github.com/apache/arrow-adbc/go/adbc/sqldriver/flightsql" -) - -func main() { - dsn := "uri=grpc://localhost:12345;username=mickeymouse;password=p@55w0RD" - db, err := sql.Open("flightsql", dsn) - ... -} -``` - -DSN option keys are expressed as `k=v`, delimited with `;`. -Some options keys are defined in ADBC, others are defined in the FlightSQL ADBC driver. -- Arrow ADBC [developer doc](https://arrow.apache.org/adbc/main/driver/flight_sql.html#client-options) -- ADBC [source code](https://github.com/apache/arrow-adbc/blob/3d12fad1bae21029a8ff25604d6e65760c3f65bd/go/adbc/adbc.go#L149-L158) -- FlightSQL driver option keys [source code](https://github.com/apache/arrow-adbc/blob/3d12fad1bae21029a8ff25604d6e65760c3f65bd/go/adbc/driver/flightsql/flightsql_adbc.go#L70-L81) - -Reference Counting ------------------- - -The library makes use of reference counting so that it can track when memory -buffers are no longer used. This allows Arrow to update resource accounting, -pool memory such and track overall memory usage as objects are created and -released. Types expose two methods to deal with this pattern. The `Retain` -method will increase the reference count by 1 and `Release` method will reduce -the count by 1. Once the reference count of an object is zero, any associated -object will be freed. `Retain` and `Release` are safe to call from multiple -goroutines. - -### When to call `Retain` / `Release`? - -* If you are passed an object and wish to take ownership of it, you must call - `Retain`. You must later pair this with a call to `Release` when you no - longer need the object. "Taking ownership" typically means you wish to - access the object outside the scope of the current function call. - -* You own any object you create via functions whose name begins with `New` or - `Copy` or when receiving an object over a channel. Therefore you must call - `Release` once you no longer need the object. - -* If you send an object over a channel, you must call `Retain` before sending - it as the receiver is assumed to own the object and will later call `Release` - when it no longer needs the object. - -Performance ------------ - -The arrow package makes extensive use of [c2goasm][] to leverage LLVM's -advanced optimizer and generate PLAN9 assembly functions from C/C++ code. The -arrow package can be compiled without these optimizations using the `noasm` -build tag. Alternatively, by configuring an environment variable, it is -possible to dynamically configure which architecture optimizations are used at -runtime. We use the (cpu)[https://pkg.go.dev/golang.org/x/sys/cpu] package to -check dynamically for these features. - -### Example Usage - -The following benchmarks demonstrate summing an array of 8192 values using -various optimizations. - -Disable no architecture optimizations (thus using AVX2): - -```sh -$ INTEL_DISABLE_EXT=NONE go test -bench=8192 -run=. ./math -goos: darwin -goarch: amd64 -pkg: github.com/apache/arrow/go/arrow/math -BenchmarkFloat64Funcs_Sum_8192-8 2000000 687 ns/op 95375.41 MB/s -BenchmarkInt64Funcs_Sum_8192-8 2000000 719 ns/op 91061.06 MB/s -BenchmarkUint64Funcs_Sum_8192-8 2000000 691 ns/op 94797.29 MB/s -PASS -ok github.com/apache/arrow/go/arrow/math 6.444s -``` - -**NOTE:** `NONE` is simply ignored, thus enabling optimizations for AVX2 and SSE4 - ----- - -Disable AVX2 architecture optimizations: - -```sh -$ INTEL_DISABLE_EXT=AVX2 go test -bench=8192 -run=. ./math -goos: darwin -goarch: amd64 -pkg: github.com/apache/arrow/go/arrow/math -BenchmarkFloat64Funcs_Sum_8192-8 1000000 1912 ns/op 34263.63 MB/s -BenchmarkInt64Funcs_Sum_8192-8 1000000 1392 ns/op 47065.57 MB/s -BenchmarkUint64Funcs_Sum_8192-8 1000000 1405 ns/op 46636.41 MB/s -PASS -ok github.com/apache/arrow/go/arrow/math 4.786s -``` - ----- - -Disable ALL architecture optimizations, thus using pure Go implementation: - -```sh -$ INTEL_DISABLE_EXT=ALL go test -bench=8192 -run=. ./math -goos: darwin -goarch: amd64 -pkg: github.com/apache/arrow/go/arrow/math -BenchmarkFloat64Funcs_Sum_8192-8 200000 10285 ns/op 6371.41 MB/s -BenchmarkInt64Funcs_Sum_8192-8 500000 3892 ns/op 16837.37 MB/s -BenchmarkUint64Funcs_Sum_8192-8 500000 3929 ns/op 16680.00 MB/s -PASS -ok github.com/apache/arrow/go/arrow/math 6.179s -``` - -[arrow]: https://arrow.apache.org -[c2goasm]: https://github.com/minio/c2goasm diff --git a/go/arrow/.editorconfig b/go/arrow/.editorconfig deleted file mode 100644 index a7ceaf938f92c..0000000000000 --- a/go/arrow/.editorconfig +++ /dev/null @@ -1,21 +0,0 @@ -# Licensed to the Apache Software Foundation (ASF) under one -# or more contributor license agreements.
