// Functions in this file support the public tag_set API, as well as
|
||||
// encoding/decoding tag_sets as part of context propagation across
|
||||
// RPC's. The overall requirements (in approximate priority order) for the
|
||||
// tag_set representations:
|
||||
// 1. Efficient conversion to/from wire format
|
||||
// 2. Minimal bytes used on-wire
|
||||
// 3. Efficient tag set creation
|
||||
// 4. Efficient lookup of value for a key
|
||||
// 5. Efficient lookup of value for an index (to support iteration)
|
||||
// 6. Minimal memory footprint
|
||||
//
|
||||
// Notes on tradeoffs/decisions:
|
||||
// * tag includes 1 byte length of key, as well as nil-terminating byte. These
|
||||
// are to aid in efficient parsing and the ability to directly return key
|
||||
// strings. This is more important than saving a single byte/tag on the wire.
|
||||
// * The wire encoding uses only single byte values. This eliminates the need
|
||||
// to handle endian-ness conversions. It also means there is a hard upper
|
||||
// limit of 255 for both CENSUS_MAX_TAG_KV_LEN and CENSUS_MAX_PROPAGATED_TAGS.
|
||||
// * Keep all tag information (keys/values/flags) in a single memory buffer,
|
||||
// that can be directly copied to the wire.14
|
||||
// * Binary tags share the same structure as, but are encoded separately from,
|
||||
// non-binary tags. This is primarily because non-binary tags are far more
|
||||
// likely to be repeated across multiple RPC calls, so are more efficiently
|
||||
// cached and compressed in any metadata schemes.
|
||||
// * all lengths etc. are restricted to one byte. This eliminates endian
|
||||
// issues.
