------------------------------------
Summary: Set file format specific values for split sizes on
non-block stores
Key: IMPALA-8942
URL: https://issues.apache.org/jira/browse/IMPALA-8942
Project: IMPALA
Issue Type: Improvement
Components: Frontend
Reporter: Sahil Takiar
Assignee: Sahil Takiar
Parquet scans on non-block based storage systems (e.g. S3, ADLS, etc.) can
suffer from uneven scan range assignment due to the behavior described in
IMPALA-3453. The frontend should set different split sizes depending on the
file type and file system.
