1. Added:
* Add 2 new proc '/current\_queries' and '/current\_backend\_instances'
to monitor the current running queries.
- * Add a manual compaction api on Backend to trigger cumulative or base
compaction manually.
- * Add Frontend config 'max\_bytes\_per\_broker\_scanner' to limit to
bytes per one broker scanner. This is to limit the memory cost of a single
broker load job.
- * Add Frontend config 'max\_unfinished\_load\_job' to limit load job
number: if number of running load jobs exceed the limit, no more load job is
allowed to be submmitted.
- * exposure backend info to user when encounter error on Backend. for
debugging it more convenient.
- * Add 3 new metrics of Backends: host\_fd\_metrics,
process\_fd\_metrics and process\_thread\_metrics, to monitor open file number
and thread number.

JDBC.
2. Updated:
- * Hide password and other sensitive information in log and audit log.
- * Change the promethues type name GAUGE to lowercase, to fit the latest
promethues version.
- * Backend ip saved in FE will be compared with BE's local ip when doing
heartbeat, to avoid false positive heartbeat response.
