-----------------------------------------
Summary: Refactoring code completion (plugins)
Key: ZEPPELIN-3368
URL: https://issues.apache.org/jira/browse/ZEPPELIN-3368
Project: Zeppelin
Issue Type: Bug
Components: interpreter-auto-completion
Reporter: Maksim Reshetov
Assignee: Maksim Reshetov
Create new entrypoint (plugin) for generate metadata. Metadata must be stored
in memory and generated immediately after the start of the server (+updated
periodically),
what problems can be solved:
# code completion is too slow (because generates in runtime), code completions
more than 1 second it is not good
# code completion does not work until the first start of the interpreter
(initialization), if interpreter is 'per user' then it is awfull
# if the interpreter (e.g. JDBC) is "per user" than we have more duplicates of
metadata. And JDBC driver loads meta by method getMetaData, if data is large
then it is too slow
extra benefits:
one entrypoint with all meta. posibility to create visual plugins for easy
navigation and viewing of available data
