Command Line Interface

RedisVL provides a command line interface (CLI) called rvl for managing vector search indices. The CLI enables you to create, inspect, and delete indices directly from your terminal without writing Python code.

Installation

The rvl command is included when you install RedisVL.

pip install redisvl

Verify the installation by running:

rvl version

Connection Configuration

The CLI connects to Redis using the following resolution order:

  1. The REDIS_URL environment variable, if set
  2. Explicit connection flags (--host, --port, --url)
  3. Default values (localhost:6379)

Connection Flags

All commands that interact with Redis accept these optional flags:

Flag Type Description Default
-u, --url string Full Redis URL (e.g., redis://localhost:6379) None
--host string Redis server hostname localhost
-p, --port integer Redis server port 6379
--user string Redis username for authentication default
-a, --password string Redis password for authentication Empty
--ssl flag Enable SSL/TLS encryption Disabled

Examples

Connect using environment variable:

export REDIS_URL="redis://localhost:6379"
rvl index listall

Connect with explicit host and port:

rvl index listall --host myredis.example.com --port 6380

Connect with authentication and SSL:

rvl index listall --user admin --password secret --ssl

Getting Help

All commands support the -h and --help flags to display usage information.

Flag Description
-h, --help Display usage information for the command

Examples

# Display top-level help
rvl --help

# Display help for a command group
rvl index --help

# Display help for a specific subcommand
rvl index create --help

Running rvl without any arguments also displays the top-level help message.

Commands

rvl version

Display the installed RedisVL version.

Syntax

rvl version [OPTIONS]

Options

Option Description
-s, --short Print only the version number without additional formatting

Examples

# Full version output
rvl version

# Version number only

Options

Option Description
-i, --index Name of the index to inspect
-s, --schema Path to the schema file (alternative to specifying index name)

Example

rvl index info -i my_index

Output

The command displays two tables:

  1. Index Information containing the index name, storage type, key prefixes, index options, and indexing status
  2. Index Fields listing each field with its name, attribute, type, and any additional field options

rvl index listall

List all vector search indices in the connected Redis instance.

Syntax

Options

Option Description
-i, --index Name of the index to destroy
-s, --schema Path to the schema file (alternative to specifying index name)

Example

rvl index destroy -i my_index
Warning:
This command permanently deletes both the index and all documents stored with the index prefix. Ensure you have backups before running this command.

rvl stats

Display statistics about an existing index, including document counts, memory usage, and indexing performance metrics.

Syntax

rvl stats (-i <index_name> | -s <schema_file>) [OPTIONS]

rvl migrate

Warning:
The index migrator is an experimental feature. APIs, CLI commands, and on-disk formats (plans, checkpoints, backups) may change in future releases. Review migration plans carefully before applying to production indexes.

Manage document-preserving index migrations. This command group provides subcommands for planning, executing, and validating schema migrations that preserve existing data.

Syntax

rvl migrate <subcommand> [OPTIONS]

Subcommands

Subcommand Description
helper Show migration guidance and supported capabilities
wizard Interactively build a migration plan and schema patch
plan Generate a migration plan from a schema patch or target schema
apply Execute a reviewed drop/recreate migration plan
estimate Estimate disk space required for a migration (dry-run)
rollback Restore original vectors from a backup directory
validate Validate a completed migration against the live index
batch-plan Generate a batch migration plan for multiple indexes
batch-apply Execute a batch migration plan with state tracking
batch-resume Resume an interrupted batch migration
batch-status Show status of an in-progress or completed batch migration

rvl migrate plan

Generate a migration plan for a document-preserving drop/recreate migration.

Syntax

rvl migrate plan --index <name> (--schema-patch <patch.yaml> | --target-schema <schema.yaml>) [OPTIONS]

Required Options

Option Description
--index, -i Name of the source index to migrate
--schema-patch Path to a YAML schema patch file (mutually exclusive with --target-schema)
--target-schema Path to a full target schema YAML file (mutually exclusive with --schema-patch)

Optional Options

Option Description
--plan-out Output path for the migration plan YAML (default: migration_plan.yaml)

Example

rvl migrate plan -i my_index --schema-patch changes.yaml --plan-out plan.yaml

rvl migrate apply

Execute a reviewed drop/recreate migration plan. Use --async for large migrations involving vector quantization.

Warning:
Hash vector quantization is unsupported when the same Redis keys are also indexed by another live RediSearch index that expects the old vector datatype. Quantization rewrites vector bytes in the document key itself, so other indexes covering the same key may drop the document or fail to index it. Use an application-level migration with new keys or fields when documents are shared across indexes.

Syntax

rvl migrate apply --plan <migration_plan.yaml> --backup-dir <dir> [OPTIONS]

Required Options

Option Description
--plan Path to the migration plan YAML file
--backup-dir Required migration backup directory. Vector backup files are written when hash vector bytes are mutated; index-only and JSON migrations validate and record the directory without writing vector backup files.

Optional Options

Option Description
--async Run migration asynchronously (recommended for large quantization jobs)
--batch-size Keys per pipeline batch (default 500)
--workers Number of parallel workers for quantization (default 1).
--query-check-file Path to a YAML file with post-migration query checks

Example

rvl migrate apply --plan plan.yaml --backup-dir /tmp/backups
rvl migrate apply --plan plan.yaml --async --backup-dir /tmp/backups --workers 4

rvl migrate wizard

Interactively build a schema patch and migration plan through a guided wizard.

Syntax

rvl migrate wizard [--index <name>] [OPTIONS]

Example

rvl migrate wizard -i my_index --plan-out plan.yaml

rvl migrate rollback

Restore original vector bytes from a retained backup directory. Rollback restores data only; recreate the original index schema separately if the index definition was changed.

Syntax

rvl migrate rollback --backup-dir <dir> [--index <name>] [OPTIONS]

Required Options

Option Description
--backup-dir Directory containing vector backup files from a prior migration

Example

rvl migrate rollback --backup-dir /tmp/backups --index my_index

rvl migrate batch-plan

Generate a batch plan that applies one shared schema patch to multiple indexes.

Syntax

rvl migrate batch-plan --schema-patch <patch.yaml> (--pattern <glob> | --indexes <name1,name2> | --indexes-file <file>) [OPTIONS]

rvl migrate batch-apply

Execute a batch migration plan and write checkpoint state for resume.

Syntax

rvl migrate batch-apply --plan <batch_plan.yaml> --backup-dir <dir> [OPTIONS]

Required Options

Option Description
--plan Path to the batch plan YAML file
--backup-dir Required per-index migration backup directory. Stored in checkpoint state and used for vector backup files when hash vector bytes are mutated.

Example

rvl migrate batch-apply --plan batch_plan.yaml --backup-dir /tmp/backups

rvl migrate batch-resume

Resume an interrupted batch migration from its checkpoint state.

Syntax

rvl migrate batch-resume --state <batch_state.yaml> [--plan <batch_plan.yaml>] [--retry-failed] [--backup-dir <dir>]

If --backup-dir is omitted, resume uses the backup directory stored in batch_state.yaml. Passing a different backup directory for the same checkpoint is rejected.

rvl migrate batch-status

Show status for an in-progress or completed batch migration.

Syntax

rvl migrate batch-status --state <batch_state.yaml>

Exit Codes

The CLI returns the following exit codes:

Code Description
0 Command completed successfully
1 Command failed due to missing required arguments or invalid input
