Synopsis

codeql database cleanup <options>... -- <database>

Description

Compact a CodeQL database on disk.

Delete temporary data, and generally make a database as small as possible on disk without degrading its future usefulness.

Options

Primary Options

<database>

[Mandatory] Path to the CodeQL database to clean up.

Low-level dataset cleanup options

--max-disk-cache=<MB>

Set the maximum amount of space that the disk cache for intermediate query results can use.

If this size is not configured explicitly, the evaluator will try to use a "reasonable" amount of cache space, based on the size of the dataset and the complexity of the queries. Explicitly setting a higher limit than this default usage will enable additional caching which can speed up later queries.

--min-disk-free=<MB>

[Advanced] Set target amount of free space on file system.

If --max-disk-cache is not given, the evaluator will try hard to curtail disk cache usage if the free space on the file system drops below this value.

--min-disk-free-pct=<pct>

[Advanced] Set target fraction of free space on file system.

If --max-disk-cache is not given, the evaluator will try hard to curtail disk cache usage if the free space on the file system drops below this percentage.

--cache-cleanup=<mode>

Select how aggressively to trim the cache. Choices include:

clear: Remove the entire cache, trimming down to the state of a freshly extracted dataset

trim (default): Trim everything except explicitly "cached" predicates.

fit: Simply make sure the defined size limits for the disk cache are observed, deleting as many intermediates as necessary.

--cleanup-upgrade-backups

Delete any backup directories resulting from database upgrades.

Common options

-h, --help

Show this help text.

-J=<opt>

[Advanced] Give option to the JVM running the command.

(Beware that options containing spaces will not be handled correctly.)

-v, --verbose

Incrementally increase the number of progress messages printed.

-q, --quiet

Incrementally decrease the number of progress messages printed.

--verbosity=<level>

[Advanced] Explicitly set the verbosity level to one of errors, warnings, progress, progress+, progress++, progress+++. Overrides -v and -q.

--logdir=<dir>

[Advanced] Write detailed logs to one or more files in the given directory, with generated names that include timestamps and the name of the running subcommand.

(To write a log file with a name you have full control over, instead give --log-to-stderr and redirect stderr as desired.)

--common-caches=<dir>

[Advanced] Controls the location of cached data on disk that will persist between several runs of the CLI, such as downloaded QL packs and compiled query plans. If not set explicitly, this defaults to a directory named .codeql in the user's home directory; it will be created if it doesn't already exist.

Available since v2.15.2.
