- total number of S3 API calls per server
- maximum wait duration for any S3 API call
This implementation is primarily meant for situations
where HDDs are not capable enough to handle the incoming
workload and there is no way to throttle the client.
This feature allows MinIO server to throttle itself
such that we do not overwhelm the HDDs.
canonicalize the ENVs such that we can bring these ENVs
as part of the config values, as a subsequent change.
- fix location of per bucket usage to `.minio.sys/buckets/<bucket_name>/usage-cache.bin`
- fix location of the overall usage in `json` at `.minio.sys/buckets/.usage.json`
(avoid conflicts with a bucket named `usage.json` )
- fix location of the overall usage in `msgp` at `.minio.sys/buckets/.usage.bin`
(avoid conflicts with a bucket named `usage.bin`
This commit fixes the env. variable in the
KMS guide used to specify the CA certificates
for the KES server.
Before the env. variable `MINIO_KMS_KES_CAPATH` has
been used - which works in non-containerized environments
due to how MinIO merges the config file and environment
variables. In containerized environments (e.g. docker)
this does not work and trying to specify `MINIO_KMS_KES_CAPATH`
instead of `MINIO_KMS_KES_CA_PATH` eventually leads to MinIO not
trusting the certificate presented by the kes server.

To allow better control the cache eviction process.
Introduce MINIO_CACHE_WATERMARK_LOW and
MINIO_CACHE_WATERMARK_HIGH env. variables to specify
when to stop/start cache eviction process.
Deprecate MINIO_CACHE_EXPIRY environment variable. Cache
gc sweeps at 30 minute intervals whenever high watermark is
reached to clear least recently accessed entries in the cache
until sufficient space is cleared to reach the low watermark.
Garbage collection uses an adaptive file scoring approach based
on last access time, with greater weights assigned to larger
objects and those with more hits to find the candidates for eviction.
Thanks to @klauspost for this file scoring algorithm

We added support for caching and S3 related metrics in #8591. As
a continuation, it would be helpful to add support for Azure & GCS
gateway related metrics as well.
This commit updates the KMS getting started guide
and replaces the legacy MinIO<-->Vault setup with a
MinIO<-->KES<-->Vault setup.
Therefore, add some architecture ASCII diagrams and
provide a step-by-step guide to setup Vault, KES and
MinIO such that MinIO can encrypt objects with KES +
Vault.
The legacy Vault guide has been moved to `./vault-legacy.md`.

Fixes scenario where zones are appropriately
handled, along with supporting overriding set
count. The new fix also ensures that we handle
the various setup types properly.
Update documentation to properly indicate the
behavior.
Fixes#8750
