10 upgrade or reshard Xapian DB(s) used by public-inbox
14 --compact | -c run public-inbox-compact(1) after indexing
15 --all copy all configured inboxes
16 --reshard=NUM change number the number of shards
17 --jobs=NUM limit parallelism to JOBS count
18 --verbose | -v increase verbosity (may be repeated)
19 --sequential-shard copy+index Xapian shards sequentially (for slow HDD)
21 index options (see public-inbox-index(1) man page for full description):
23 --no-fsync speed up indexing, risk corruption on power outage
24 --batch-size=BYTES flush changes to OS after a given number of bytes
25 --max-size=BYTES do not index messages larger than the given size
27 See public-inbox-xcpdb(1) man page for full documentation.
