-------------------------------------------------------
Commit 05043e6aba6ab45c1b77de9f0762de3dfc5a54c0 in kudu's branch
refs/heads/branch-1.17.x from Alexey Serbin
[ https://gitbox.apache.org/repos/asf?p=kudu.git;h=05043e6ab ]
KUDU-3619 disable KUDU-3367 behavior by default
As it turned out, KUDU-3367 has introduced a regression due to
a deficiency in its implementation, where major compactions would fail
with errors like below if it had kicked in:
Corruption: Failed major delta compaction on RowSet(1): No min key found:
CFile base data in RowSet(1)
Since KUDU-3367 isn't quite relevant in Kudu versions of 1.12.0 and
newer when working with data that supports live row count (see
KUDU-1625), a quick-and-dirty fix is to set the default value for the
corresponding flag --all_delete_op_delta_file_cnt_for_compaction
to a value that effectively disables KUDU-3367 behavior.
This patch does exactly so.

> If we get a REDO delta with full of delete op, wich means there is no update
> op in the file. The current compact algorithm will not schedule the file do
> compact. If such files exist, after accumulating for a period of time, it
> will greatly affect our scan speed. However, processing such files every time
> compact reduces compact's performance.
