Redis Key Analyzer is a CLI tool for scanning and analyzing Redis database keys, providing insights into their distribution, type, memory usage, and TTL.

redis-key-analyzer

Overview

redis-key-analyzer is a tool designed to analyze Redis keys, providing detailed statistics on key patterns, memory usage, TTL (Time to Live), and more. This tool is useful for understanding the distribution and characteristics of keys in a Redis database, which can help in optimizing and managing Redis instances.

Features

• Analyze Redis keys based on patterns, prefixes, and separators.
• Collect statistics on key types, memory usage, and TTL.
• Support for read-only Redis clusters.
• Configurable batch size and sleep intervals for large datasets.

Installation

To install redis-key-analyzer, use pip:

pip install rka

Usage

You can use the redis-key-analyzer via the command line interface (CLI). Below are the available options:

Usage: redis-key-analyzer [OPTIONS]

Options:
  --host TEXT          Redis host. Default is 'localhost'.
  --port INTEGER       Redis port. Default is 6379.
  --db INTEGER         Redis database. Default is 0.
  --read-only, -ro     Check read-only cluster.
  --match, -m TEXT     Redis key pattern. Default is '*'.
  --batch-size INTEGER Batch size. Default is 1000.
  --prefix TEXT        Prefixes for key pattern. Example: --prefix 'prefix1 prefix2'.
  --separator TEXT     Separators for key pattern. Default is ':'.
  --limit INTEGER      Limit total keys. -1 for no limit. Default is -1.
