Closed scwagner closed 3 years ago

scwagner commented 3 years ago

ArcadeDB Version: v21.11.1-SNAPSHOT (build ef7ba86106765c5ce63ea02834edb757b8ce4797/1636054159638/main

JDK Version: openjdk version "11.0.13" 2021-10-19

OS: Alpine Linux v3.14

Expected behavior

Following the directions from the documentation to enable the Redis driver from https://docs.arcadedb.com/#Redis-API:

docker run --rm -p 2480:2480 -p 2424:2424 --env arcadedb.server.rootPassword=playwithdata --env arcadedb.server.plugins="Redis:com.arcadedb.redisw.RedisProtocolPlugin" arcadedata/arcadedb:latest

indicates that it will output the message that the driver has been loaded.

Actual behavior

An error message during server startup:

com.arcadedb.server.ServerException: Error on loading plugin from class 'Redis:com.arcadedb.redisw.RedisProtocolPlugin; at com.arcadedb.server.ArcadeDBServer.registerPlugins(ArcadeDBServer.java:194) at com.arcadedb.server.ArcadeDBServer.start(ArcadeDBServer.java:132) at com.arcadedb.server.ArcadeDBServer.main(ArcadeDBServer.java:89) Caused by: java.lang.ClassNotFoundException: com.arcadedb.redisw.RedisProtocolPlugin at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:581) at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:178) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:522) at java.base/java.lang.Class.forName0(Native Method) at java.base/java.lang.Class.forName(Class.java:315) at com.arcadedb.server.ArcadeDBServer.registerPlugins(ArcadeDBServer.java:183) ... 2 more

Steps to reproduce

Execute the docker run command quoted above.

It would appear after digging into the code that the package name is com.arcadedb.redis, not com.arcadedb.redisw.

Turns out that changing the command to be

docker run --rm -p 2480:2480 -p 2424:2424 --env arcadedb.server.rootPassword=playwithdata --env arcadedb.server.plugins="Redis:com.arcadedb.redis.RedisProtocolPlugin" arcadedata/arcadedb:latest

fixes the issue and it loads the plugin just fine.

Great it works and thanks for the sponsorship!

Please note the Redis plugin is a prototype, we're looking forward for feedback about the most common use cases instead of implementing all the Redis commands. I've just updated the documentation about the available commands.
