Compact a bucket

SYNTAX

couchbase-cli bucket-compact [--cluster <url>] [--username <user>]
          [--password <password>] [--bucket <name>]

DESCRIPTION

Starts compaction of view index and data files for a specified bucket. To compact view index files only, specify the --view-only option. To compact data files only, specify the --data-only option. Only Couchbase buckets can be compacted: Ephemeral and Memcached buckets cannot be compacted.

OPTIONS

-c
--cluster

Specfies the hostname of a node in the cluster. See the HOST FORMATS section for more information on specifying a hostname.

-u
--user <username>

Specifies the username of the user executing the command. If you do not have a user account with permision to execute the command then it will fail with an unauthorized error.

-p
--password <password>

Specifies the password of the user executing the command. If you do not have a user account with permision to execute the command then it will fail with an unauthorized error. If this argument is specified, but no password is given then the command will prompt the user for a password through non-echoed stdin. You may also specify your password by using the environment variable CB_REST_PASSWORD.

--bucket

The name of the bucket on which to perform compaction.

--data-only

Indicates that only data files should be compacted, and that compaction for view index files should therefore be skipped. This option cannot be specified at the same time as the --view-only option.

--view-only

Indicates that only view index files should be compacted, and that compaction for data files should therefore be skipped. This option cannot be specified at the same time as the --data-only option.

HOST FORMATS

When specifying a host for the couchbase-cli command the following formats are expected:

  • couchbase://<addr>

  • <addr>:<port>

  • http://<addr>:<port>

It is recommended to use the couchbase://<addr> format for standard installations. The other two formats allow an option to take a port number which is needed for non-default installations where the admin port has been set up on a port other that 8091.

EXAMPLES

To start compaction of both data and view index files for a bucket named "travel-data", run the following command.

$ couchbase-cli bucket-compact -c 192.168.1.5:8091 --username Administrator \
 --password password --bucket travel-data

If view index files only should be compacted for a specific bucket, and data files thereby skipped, run the following command.

$ couchbase-cli bucket-compact -c 192.168.1.5:8091 --username Administrator \
 --password password --bucket travel-data --view-only

If data files only should be compacted for a specific bucket, and view index files thereby skipped, run the following command.

$ couchbase-cli bucket-compact -c 192.168.1.5:8091 --username Administrator \
 --password password --bucket travel-data --data-only
