---------------------------------------
Summary: Need to create a utility for auto-schema loading from
databases
Key: IGNITE-32
URL: https://issues.apache.org/jira/browse/IGNITE-32
Project: Ignite
Issue Type: Bug
Components: UI
Reporter: Dmitriy Setrakyan
Priority: Critical
Fix For: sprint-1
Need to create utility for auto-schema loading:
# Should be written in Java
# Preferably no additional dependencies should be added to the project.
The process is composed of 2 parts, schema mapping and automatic data loading.
h3. Schema Mapping
# Should be a standalone GUI utility
# Users should select schemas, then tables from schemas, then fields from
tables, and automatically generate Spring XML for SQL Query metadata
configuration.
# Should also optionally automatically generate POJO classes.
# Should automatically map SQL table names to Java standard allowing users to
provide customer Regex.
# By default, every table should be mapped to a separate Cache, but user
should be able to override this in any possible way.
h3. Automatic {{GridCacheStore}} implementation
# The new {{GridCacheStore}} implementation should read the XML configuration
generated by *Schema Mapping* step and automatically implement all CRUD and TX
operations out of the box.
# The implementation of the {{loadCache(...)}} method should accept SQL for
loading (or where clause) as a parameter. Users should be able to preload a
portion of the table based on some search criteria on startup or at any point
after.
