### Describe the bug, including details regarding any error messages, version, and platform. On 32-bit test, when calling a write buffered with the pqarrow's FileWriter I see a panic due to unaligned operation. I believe this is due to the various `atomic.AddInt64` calls, in this case specifically [this one](https://github.com/apache/arrow/blob/5c64f74cf2840b37893d8158475676c290fa6615/go/parquet/pqarrow/path_builder.go#L509), but this appears to be used by both `pathBuilder` and `multipathLevelBuilder`. From the Go docs on this function: > AddInt64 atomically adds delta to *addr and returns the new value. Consider using the more ergonomic and less error-prone [Int64.Add](https://pkg.go.dev/sync/atomic#Int64.Add) instead (particularly if you target 32-bit platforms; see the bugs section). From the bugs section: > On ARM, 386, and 32-bit MIPS, it is the caller's responsibility to arrange for 64-bit alignment of 64-bit words accessed atomically via the primitive atomic functions (types [Int64](https://pkg.go.dev/sync/atomic#Int64) and [Uint64](https://pkg.go.dev/sync/atomic#Uint64) are automatically aligned). The first word in an allocated struct, array, or slice; in a global variable; or in a local variable (because the subject of all atomic operations will escape to the heap) can be relied upon to be 64-bit aligned. ## Steps to reproduce You can reproduce this by using `GOARCH=386`: ```sh git clone g...@github.com:powersj/telegraf -b feat/parquet-serializer cd telegraf GOARCH=386 go test -v ./plugins/outputs/parquet/... ``` ## Trace ```s === FAIL: plugins/outputs/parquet TestCases (0.00s) panic: unaligned 64-bit atomic operation [recovered] panic: unaligned 64-bit atomic operation goroutine 7 [running]: testing.tRunner.func1.2({0x902af40, 0x93eb378}) /usr/local/go/src/testing/testing.go:1631 +0x2a3 testing.tRunner.func1() /usr/local/go/src/testing/testing.go:1634 +0x434 panic({0x902af40, 0x93eb378}) /usr/local/go/src/runtime/panic.go:770 +0x103 runtime/internal/atomic.panicUnaligned() /usr/local/go/src/runtime/internal/atomic/unaligned.go:8 +0x2d runtime/internal/atomic.Xadd64(0xb43e9ac, 0xffffffffffffffff) /usr/local/go/src/runtime/internal/atomic/atomic_386.s:125 +0x11 github.com/apache/arrow/go/v16/parquet/pqarrow.(*multipathLevelBuilder).Release(0xb43e960) /go/pkg/mod/github.com/apache/arrow/go/v16@v16.1.0/parquet/pqarrow/path_builder.go:509 +0x3a github.com/apache/arrow/go/v16/parquet/pqarrow.(*arrowColumnWriter).Write(0xb275c40, {0x93f7990, 0xb3c0d38}) /go/pkg/mod/github.com/apache/arrow/go/v16@v16.1.0/parquet/pqarrow/encode_arrow.go:198 +0x1b9 github.com/apache/arrow/go/v16/parquet/pqarrow.(*FileWriter).WriteColumnChunked(0xb3e3200, 0xb3b4f30, 0x0, 0x1) /go/pkg/mod/github.com/apache/arrow/go/v16@v16.1.0/parquet/pqarrow/file_writer.go:330 +0xf7 github.com/apache/arrow/go/v16/parquet/pqarrow.(*FileWriter).WriteColumnData(0xb3e3200, {0x9401564, 0xb3b49f0}) /go/pkg/mod/github.com/apache/arrow/go/v16@v16.1.0/parquet/pqarrow/file_writer.go:339 +0x109 github.com/apache/arrow/go/v16/parquet/pqarrow.(*FileWriter).WriteBuffered(0xb3e3200, {0x9400770, 0xb3c7de0}) /go/pkg/mod/github.com/apache/arrow/go/v16@v16.1.0/parquet/pqarrow/file_writer.go:203 +0x413 github.com/influxdata/telegraf/plugins/outputs/parquet.(*Parquet).Write(0xb275f70, {0xb442520, 0x1, 0x1}) /go/src/github.com/influxdata/telegraf/plugins/outputs/parquet/parquet.go:119 +0x5d9 github.com/influxdata/telegraf/plugins/outputs/parquet.TestCases.func1(0xb362508) /go/src/github.com/influxdata/telegraf/plugins/outputs/parquet/parquet_test.go:132 +0x118 testing.tRunner(0xb362508, 0xb3c7b00) /usr/local/go/src/testing/testing.go:1689 +0x125 created by testing.(*T).Run in goroutine 6 /usr/local/go/src/testing/testing.go:1742 +0x3b9 DONE 7368 tests, 277 skipped, 2 failures in 133.817s ``` ### Component(s) Go -- This is an automated message from the Apache Git Service.
