It closes #879.
The current implementation supports
FUNCTION LOAD
,FUNCTION DELETE
,FCALL
andFUNCTION LIST
.Compatibility: Some information in
FUNCTION LIST
is currently missing. Besides,FUNCTION LISTFUNC
is added as an extension which can fit our storage structure better.The lazy-import strategy: Lua libraries do not need to be imported to the Lua runtime immediately while it is written to the storage. It can be imported while one of functions in the library is called via FCALL. This design makes the scripting more easily to work in read-only script mode, replication and data migration.
