TODO

Some notes about what I intend to be working on next. You can sponsor any and all of those ideas if you actually need them today, and you can also sponsor new ideas not on the list yet.

New Features

Filtering

Add commands to pick different target tables depending on the data found when reading from the source.

Data Formats

CSV

• see about schema discovery (column names and types)

JSON

Propose to load JSON either in a "document" column, or to normalize it by applying some advanced filtering.

Implement PostgreSQL JSON operators and functions in pgloader to help setup the normalisation steps: PostgreSQL JSON Functions and Operators.

XML

Add an XML reader to load XML documents into the database as a column value, and XSLT capabilities to normalize the XML contents into a proper relational model.

Other databases

Add support for full data and schema migrations for the following:

• SQL Server
• Sybase
• Oracle

User Interface, User Experience

Improve parse error messages

WIP, see https://github.com/nikodemus/esrap/issues/26

Graphical User Interface

Most probably a web based tool, with guidance to setup the migration, maybe not even something very sophisticated, but making the simple cases way simpler.

Database support

MySQL Support

• Convert SQL dialect for SQL views
• Triggers and Stored Procedures

SQLite support
