test_filter * more of test_filter.py working with the exception of some date pytests * Add workflow to keep datafusion dev branch up to date (#440) * Include setuptools-rust in conda build recipie, in host and run * Remove PyArrow dependency * rebase with datafusion-sql-planner * refactor changes that were inadvertent during rebase * timestamp with loglca time zone * Include RelDataType work * Include RelDataType work * Introduced SqlTypeName Enum in Rust and mappings for Python * impl PyExpr.getIndex() * add getRowType() for logical.rs * Introduce DaskTypeMap for storing correlating SqlTypeName and DataTypes * use str values instead of Rust Enums, Python is unable to Hash the Rust Enums if used in a dict * linter changes, why did that work on my local pre-commit?? * linter changes, why did that work on my local pre-commit?? * Convert final strs to SqlTypeName Enum * removed a few print statements * Temporarily disable conda run_test.py script since it uses features not yet implemented * expose fromString method for SqlTypeName to use Enums instead of strings for type checking * expanded SqlTypeName from_string() support * accept INT as INTEGER * Remove print statements * Default to UTC if tz is None * Delegate timezone handling to the arrow library * Updates from review Co-authored-by: Charles Blackmon-Luca <20627856+charlesbluca@users.noreply.github.com>
