RAMP

Redis Automatic Module Packaging

Similar to npm init, this packer bundles Redis Modules for later distribution.

It gathers information from modules e.g. module's name, command list, version and additional metadata.

Prerequisites

Make sure redis-server is on your PATH

export PATH=$PATH:<PATH_TO_REDIS>

Install

You can either use pip install or the setup.py script

pip install ramp-packer

python setup.py install

Usage

Manifest mode

ramp pack <PATH_TO_RedisModule.so> -m <PATH_TO_Manifest.yml>

manifest.yml should specify your module's attributes, the ones you would specify manualy if you were to use the Command line mode, see Full usage options and manifest.yml for a reference.

Command line mode

ramp pack <PATH_TO_RedisModule.so> -a <author> -e <email> -A <architecture> -d <description> -h <homepage> -l <license> -c <cmdargs> -r <redis-min-version>

Module Capabilities

Following is a list of capabilities which can be specified for a module

capability	description
types	module has its own types and not only operate on existing redis types
no_multi_key	module has no methods that operate on multiple keys
replica_of	module can work with replicaof capability when it is loaded into a source or a destination database
backup_restore	module can work with import/export capability
eviction_expiry	module is able to handle eviction and expiry without an issue
reshard_rebalance	module is able to operate in a database that is resharded and rebalanced
failover_migrate	module is able to operate in a database that is failing over and migrating
persistence_aof	module is able to operate in a database when database chooses AOF persistence option
persistence_rdb	module is able to operate in a database when database chooses SNAPSHOT persistence option
hash_policy	module is able to operate in a database with a user defined HASH POLICY
flash	module is able to operate in a database with Flash memory is enabled or changed over time
crdb	module is able to operate in a database with crdt for the default redis data types
clustering	module is able to operate in a database that is sharded and shards can be migrated

Output

ramp pack generates module.zip

Which contains:

1. RedisModule.so - original module
2. Module.json - module's metadata
