--
-
Separates an option from an argument that could be mistaken for an option.
-c
,--connections-per-host num_connections
-

streaming_connections_per_host
incassandra.yaml
. -ks
,--keyspace keyspace_name
,…
-
Comma-separated list of one or more keyspaces. List only the keyspaces to include in the rebuild.
Do not include keyspaces that are not replicated across datacenters (for example, dsefs keyspaces, and keyspaces with local strategy).
-m
,--mode mode
-
-
normal
- conventional behavior, streams only ranges that are not already locally available -
refetch
- resets locally available ranges, streams all ranges but leaves current data untouched -
reset
- resets the locally available ranges, removes all locally present data (like aTRUNCATE
), streams all ranges -
reset-no-snapshot
- (likereset
) resets the locally available ranges, removes all locally present data (like aTRUNCATE
), streams all ranges but prevents a snapshot even ifauto_snapshot
is enabled When not specified, the default is normal.
-
-s
,--sources source_ip_address
-
Comma-separated list of IP addresses from which to stream.
-ts
,--tokens (start_token_1,end_token_1], (start_token_2,end_token_2], …
-
Comma-separated list of token ranges, in this format
(start_token_1,end_token_1],(start_token_2,end_token_2],(start_token_n,end_token_n]
-x
,--exclude-sources exclude_source_IPs
-
Comma-separated list of IP addresses to exclude from streaming.
-xdc
,--exclude-dcs exclude_dc_name
-
Comma-separated list of datacenters to exclude from streaming. For example,
dc-a,dc-b
. To include a rack name in the list, separate datacenter and rack name with a colon (:). For example,dc-a:rack1,dc-a:rack2
.
Examples
Rebuild from any datacenter
nodetool rebuild
Rebuild from DC2
nodetool rebuild -dc DC2
Rebuild from DC2 and DC3
