132 
133 Performance ralevant:
134 --analyze=s -- Run analyze table after archive.
135 --optimize=s -- Run optimize table after archive.

137 --buffer -- Buffer output to file and flush when commit.
138 --bulk-delete -- Delete by chunk.
139 --bulk-insert -- Insert by chunk.
140 --limit=i -- Rows of per statment when arching,default 1.
141 --txn-size=i -- Rows of per trx,default 1.
142 --primary-key-only -- Merely use primary key.
143 
144 Infermation output:
145 --progress=i  -- Print per i rows.
146 --statistics -- Print time statistics.
147 
148 Others parameters:
149 --dry-run -- Just print queries without real doing.
150 --retries=i -- Times of when retry,default 1.

158   --share-lock and --for-update are mutually exclusive.
159   --analyze and --optimize are mutually exclusive.  -- I don't recommend use "analyze" or "optimize" when archive tables simultaneously,but afterward does when business not busy.
