## Storage usage

The selection of varying data and parity drives has a direct impact on the drive space usage. With storage class, you can optimize for high
redundancy or better drive space utilization.

To get an idea of how various combinations of data and parity drives affect the storage usage, let’s take an example of a 100 MiB file stored

                            + "healthChecks=%d, failed=%d, removed=%d, endpoints=%d, "
                            + "healthCheckEnabled=%s, proactiveEnabled=%s, utilization=%.2f%%, successRate=%.2f%%]",
                    activeConnections, nonPooledConnections, trackedConnections, maxPoolSize, totalHealthChecks, failedHealthChecks,

- 一個 bash 腳本先跑前置步驟，然後再啟動你的應用
    - 你仍然需要有機制來啟動／重新啟動「那個」bash 腳本、偵測錯誤等

## 資源使用率 { #resource-utilization }

你的伺服器（群）是可以被「消耗／利用」的「資源」，你的程式會使用 CPU 的計算時間，以及可用的 RAM 記憶體。

你想要消耗／利用多少系統資源？直覺上可能會想「不要太多」，但實際上，你大概會希望在「不當機」的前提下「盡可能用多一點」。

如果你花錢租了 3 台伺服器，卻只用了它們少量的 RAM 與 CPU，那你可能是在「浪費金錢」💸、也「浪費伺服器電力」🌎 等。

    * Function is linear between points. Resource utilization is defined as one minus ratio of total amount of resource requested by pods on node and node's capacity (scaled to 100).

new APIs so we can get out of alpha.

 *  New: Support Java 21's virtual threads (‘OpenJDK Project Loom’). We changed OkHttp's internals
    to use `Lock` and `Condition` instead of `synchronized` for best resource utilization.

 *  New: Switch our Internationalized Domain Name (IDN) implementation to [UTS #46 Nontransitional
    Processing][uts46]. With this fix, the `ß` code point no longer maps to `ss`. OkHttp now embeds

  - `priority_level_seat_count_watermarks` is removed.
  - `priority_level_request_count_samples` is replaced with `priority_level_request_utilization`, which samples every nanosecond rather than every millisecond; the old metric conveyed utilization despite its name.
