# The linters can take a lot of resources and are slow, so they can be
|
||
|
# configured using the following environment variables:
|
||
|
|
#
|
||
|
|
# - `DENDRITE_LINT_CONCURRENCY` - number of concurrent linters to run,
|
||
|
|
# golangci-lint defaults this to NumCPU
|
||
|
|
# - `GOGC` - how often to perform garbage collection during golangci-lint runs.
|
||
|
|
# Essentially a ratio of memory/speed. See https://github.com/golangci/golangci-lint#memory-usage-of-golangci-lint
|
||
|
|
# for more info.
