etlantic-pandas
Pandas dataframe plugin and portable transform compiler for
ETLantic 0.43. Install when
you select Profile(dataframe_engine="pandas") or need portable DTCS
compilation on Pandas. Keep the pin matched to core.
Note: This plugin and ETLantic core use Beta classifiers for documented single-tenant pilots. Classifiers are not an enterprise SLA.
Install
pip install 'etlantic-pandas==0.59.0'
# Optional Arrow interchange:
pip install 'etlantic-pandas[arrow]==0.59.0'
# pip install 'etlantic==0.59.0'
Dataframe plugin
The plugin provides eager, index-neutral DataFrame execution. It copies
frames at ownership boundaries so Pandas index state and in-place mutation do
not leak into portable pipeline semantics. Planning fails closed when a
pipeline requires unsupported lazy or zero-copy behavior.
Select it with Profile(dataframe_engine="pandas"); the
etlantic.dataframe_plugins entry point named pandas registers the plugin.
Portable transform compiler
The etlantic.transform_compilers entry point named pandas exposes
etlantic_pandas:create_transform_compiler. The eager compiler claims
dtcs:profile/portable-relational-kernel/1 and
dtcs:profile/portable-relational/1, including joins, unions, grouping,
aggregation, ordering, deduplication, and limits without requiring a native
@implementation("pandas").
This is the recommended transformation path and remains eligible for adaptive
execution; a native Pandas body pins its step to Pandas.
from etlantic import Profile
profile = Profile(
name="pandas-portable",
dataframe_engine="pandas",
portable_transform_policy="require",
)
Plugin authors can verify the advertised portable behavior with the public conformance suite:
from etlantic.testing import run_portable_transform_conformance_suite
from etlantic_pandas import create_transform_compiler
run_portable_transform_conformance_suite(create_transform_compiler())
