The cockroach userfile delete command deletes the files stored in the user-scoped file storage which match the provided pattern, using a SQL connection. If the pattern '*' is passed, all files in the specified (or default, if unspecified) user-scoped file storage will be deleted. Deletions are not atomic, and all deletions prior to the first failure will occur.
Required privileges
The user must have the CREATE privilege on the target database. CockroachDB will proactively grant the user GRANT, SELECT, INSERT, DROP, DELETE on the metadata and file tables.
A user can only delete files from their own user-scoped storage, which is accessed through the userfile URI used during the upload. CockroachDB will revoke all access from every other user in the cluster except users in the admin role. Users in the admin role can delete from any user's storage.
Synopsis
Delete a file:
$ cockroach userfile delete <file | dir> [flags]
View help:
$ cockroach userfile delete --help
Flags
| Flag | Description |
|---|---|
--cert-principal-map |
A comma-separated list of <cert-principal>:<db-principal> mappings. This allows mapping the principal in a cert to a DB principal such as node or root or any SQL user. This is intended for use in situations where the certificate management system places restrictions on the Subject.CommonName or SubjectAlternateName fields in the certificate (e.g., disallowing a CommonName like node or root). If multiple mappings are provided for the same <cert-principal>, the last one specified in the list takes precedence. A principal not specified in the map is passed through as-is via the identity function. A cert is allowed to authenticate a DB principal if the DB principal name is contained in the mapped CommonName or DNS-type SubjectAlternateName fields. |
--certs-dir |
The path to the certificate directory containing the CA and client certificates and client key. Env Variable: COCKROACH_CERTS_DIRDefault: ${HOME}/.cockroach-certs/ |
--echo-sql |
Reveal the SQL statements sent implicitly by the command-line utility. |
--url |
A connection URL to use instead of the other arguments. Env Variable: COCKROACH_URLDefault: no URL |
--user-u |
The SQL user that will own the client session. Env Variable: COCKROACH_USERDefault: root |
Examples
Delete all files in the default storage
To delete all files in the directory, pass the '*' pattern:
$ cockroach userfile delete '*' --certs-dir=certs
deleted userfile://defaultdb.public.userfiles_root/test-data-2.csv
deleted userfile://defaultdb.public.userfiles_root/test-data.csv
deleted userfile://defaultdb.public.userfiles_root/test-upload/test-data.csv
Note that because a fully qualified userfile URI was not specified, files in the default user-scoped storage (userfile://defaultdb.public.userfiles_$user/) were deleted.
Delete a specific file
To delete a specific file, include the file destination in the command:
$ cockroach userfile delete test-data.csv --certs-dir=certs
deleted userfile://defaultdb.public.userfiles_root/test-data.csv
Delete files that match the provided pattern
To delete all files that match a pattern, use *:
$ cockroach userfile delete '*.csv' --certs-dir=certs
deleted userfile://defaultdb.public.userfiles_root/test-data-2.csv
deleted userfile://defaultdb.public.userfiles_root/test-data.csv
Delete files from a non-default userfile URI
If you uploaded a file to a non-default userfile URI (e.g., userfile://testdb.public.uploads):
cockroach userfile upload /Users/maxroach/Desktop/test-data.csv userfile://testdb.public.uploads/test-data.csv
Use the same URI to delete it:
cockroach userfile delete userfile://testdb.public.uploads
