Hostcachedbit

Hostcachedbit is a command in the Redis command line tool. It's a flag that can be added to the hostcached command to enable or disable the caching of host-mapped bits.

When the hostcachedbit flag is used with the health or status command, Redis will display the cache statistics and the hit/miss ratio for the host-mapped bits. This can be helpful for monitoring the caching performance and identifying potential issues.

The hostcachedbit flag can also be used with the flush command to clear the cache of host-mapped bits. This can be useful for debugging purposes or when updating the host-mapped bits.

In addition, the hostcachedbit flag can be used with the trace command to enable caching of host-mapped bits. This can be useful for performance debugging and tracing.

The hostcachedbit flag is optional and can be set to 0 or 1, where 0 disables the caching of host-mapped bits and 1 enables it. If the flag is not specified, the caching of host-mapped bits is disabled by default.

The hostcachedbit flag is only available when the host-mapped bits are enabled in the Redis configuration file. If the host-mapped bits are disabled, the hostcachedbit flag is ignored and caching of host-mapped bits is not performed.

In summary, the hostcachedbit flag is a useful tool for monitoring and debugging the caching of host-mapped bits in Redis. It provides a way to enable or disable the caching of host-mapped bits, clear the cache, and enable caching for performance debugging.
