# Available Go build tags, with explanation, followed by benefits of enabling it:
|
|
# - kvformat: enables prettier output of log fields (slightly better performance)
|
|
# - timetzdata: embed timezone database inside binary (allow setting local time inside Docker containers, at cost of 450KB)
|
|
# - notracing: disables compiling-in otel tracing support (reduced binary size, better performance)
|
|
# - nometrics: disables compiling-in otel metrics support (reduced binary size, better performance)
|
|
# - noerrcaller: disables caller function prefix in errors (slightly better performance, at cost of err readability)
|
|
# - debug: enables /debug/pprof endpoint (adds debug, at performance cost)
|
|
# - debugenv: enables /debug/pprof endpoint if DEBUG=1 env during runtime (adds debug, at performance cost)
|
|
# - wasmsqlite3: uses SQLite through WASM instead of the C-to-Go transpilation (experimental)
