Hi rocksdb folks, I am using rocksdb 6.20.3, actually rockdbjni in apache ozone project, and when I start my app daemon, I could see rocksdb threads like

$ ps -T -p 13041 | grep rocksdb

13041 13100 ? 00:00:00 rocksdb:low0

13041 13101 ? 00:00:00 rocksdb:low1

13041 13102 ? 00:00:00 rocksdb:low2

13041 13103 ? 00:00:00 rocksdb:low3

13041 13104 ? 00:00:00 rocksdb:low4

13041 13105 ? 00:00:00 rocksdb:low5

13041 13106 ? 00:00:00 rocksdb:low6

13041 13107 ? 00:00:00 rocksdb:low7

13041 13108 ? 00:00:00 rocksdb:low8

13041 13109 ? 00:00:00 rocksdb:low9

13041 13110 ? 00:00:00 rocksdb:low10

13041 13111 ? 00:00:00 rocksdb:low11

13041 13112 ? 00:00:00 rocksdb:low12

13041 13113 ? 00:00:00 rocksdb:low13

13041 13114 ? 00:00:00 rocksdb:low14

13041 13115 ? 00:00:00 rocksdb:low15

13041 13116 ? 00:00:00 rocksdb:high0

13041 16422 ? 00:00:00 rocksdb:high1

But there are no rocksdb:dump_st and rocksdb:pst_st threads ?

Are they gone or merged into other threads?

I'm sure that I've turn the statistics on, because I can see the metrics exported on prometheus.
