daniellavoie opened a new issue #6520:
URL: https://github.com/apache/incubator-pinot/issues/6520
It would be very helpful for operation purpose to have the ability to get
quick overview on the reload status of a table.
All I could find for now is the `GET
/segments/{tableName}_OFFLINE/metadata?type=OFFLINE`. As I'm exploring its
output, I realize that the reload status is specific to each individual
segments. While providing a startree status there would be a good step forward,
a global status would greatly improve the operation experience.
### Output from metadata endpoint
```
"myTable_OFFLINE_1602111600000_1602111600000_2670" : {
"segmentName" : "myTable_OFFLINE_1602111600000_1602111600000_2670",
...
"columns" : [ ],
"indexes" : {
"column1" : {
"bloom-filter" : "NO",
"dictionary" : "YES",
"forward-index" : "YES",
"inverted-index" : "NO",
"null-value-vector-reader" : "NO",
"range-index" : "NO"
},
"column2" : {
"bloom-filter" : "NO",
"dictionary" : "YES",
"forward-index" : "YES",
"inverted-index" : "NO",
"null-value-vector-reader" : "NO",
"range-index" : "NO"
},
}
}
```
## Exposing reload status as JMX Metrics
In addition to a global status, exposing the individual reload status as
well as the global status would be very helpful in regards to configuration
alerts on a prometheus stack.
