---------------------------------------
Summary: Frame data type support
Key: SYSTEMML-554
URL: https://issues.apache.org/jira/browse/SYSTEMML-554
Project: SystemML
Issue Type: Epic
Components: APIs, Compiler, Parser, Runtime
Reporter: Matthias Boehm
Assignee: Matthias Boehm
SystemML natively supports two data types: MATRIX and SCALAR, where matrices
support value type double and scalars support values types boolean, string,
integer (long), and double. With the introduction of 'transform', we already
added a new data type FRAME to the compiler but without full language and
runtime support having transform directly read csv inputs and transform
specification files.
In order to simplify the use of tables with schema on input and output side as
well as in combination with matrices, this epic aims to fully integrate FRAMEs
into SystemML's language, compiler and runtime. Beside flexibility on script
level, this will also allow for a seamless integration with other APIs like
JMLC and MLContext, where we do not necessarily consume frames from files but
directly from in-memory objects.
