Still going through the list. Thanks for compiling this. This is awesome work and super-useful
for the Samza community!

    Can you rephrase the description as "Number of commit method calls at TaskInstance level"
so as to clearly distinguish it from Container's commit method call metrics? I understand
it belongs to a different group. It will be better to distinguish them clearly.
    
    Or you can add a subtitle common to all metrics under "TaskInstanceMetrics" implying that
the following apply to each TaskInstance



docs/learn/documentation/versioned/container/metrics-table.html (line 243)
<https://reviews.apache.org/r/51516/#comment214697>

    nit: "Number of messages actually processed by a task"



docs/learn/documentation/versioned/container/metrics-table.html (line 247)
<https://reviews.apache.org/r/51516/#comment214698>

    I actually don't see any difference between "send-calls" and "messages-sent". Both are
technically the same. We should consider removing one of them. At least, deprecating one of
them in the current version.
