CBOR codec usage can easily be optimized by not recreating options and modes each time

[x448]

The CBOR codec is optimized for encoding and decoding modes to be created at startup just once and then reused concurrently.

Recreating options & modes on each call to encode like this creates overhead:

otel-arrow-adapter/pkg/otel/common/cbor.go

Line 45 in bca2620

em, err := cbor.EncOptions{Sort: cbor.SortCanonical}.EncMode()

Quick Start has a section about using modes:

Here's a more extensive example with security considerations:

For determinism, this returns presets for Core Deterministic Encoding Requirements as defined in IETF STD 94 (RFC 8949):

func CoreDetEncOptions() EncOptions
