 Description   

if you have a table with a primary key and no secondary keys, this variable:
rocksdb-blind-delete-primary-key=1
should allow you to delete faster, but in reality, does not delete all
for example a table like:

CREATE TABLE lrntest (
 
  did varchar(10) NOT NULL DEFAULT '',
 
  lrn varchar(10) DEFAULT NULL,
 
  PRIMARY KEY (did)
 
)
 
ENGINE = ROCKSDB,
 
AVG_ROW_LENGTH = 12,
 
CHARACTER SET latin1,
 
COLLATE latin1_swedish_ci,
 
STATS_AUTO_RECALC = 1,
 
STATS_PERSISTENT = 1,
 
ROW_FORMAT = DYNAMIC;
