Impala actions that produce Atlas entities

Impala operations that create, update, or delete Hive metadata will affect Atlas entities; operations that only affect data do not show up in Atlas.

The following table lists the Impala actions that produce or update metadata in Atlas.


This Action in Impala...	...Produces metadata for these Atlas entities	...Triggers HMS to produce metadata for these Atlas entities	...Produces metadata for these Atlas relationships
CREATETABLE_AS_SELECT	impala_process, impala_process_execution, impala_column_lineage, hive_db hive_table_ddl	hive_table, hive_column(s), hive_storagedesc, hive_db hive_table_ddl	hive_table_db, hive_table_columns, hive_table_partitionkeys, hive_table_storagedesc, hive_process_process_execution, hive_process_columnlineage, hive_table_ddl_queries, hive_db_ddl_queries
CREATEVIEW	impala_process, impala_process_execution, impala_column_lineage, hive_table_ddl	hive_table, hive_column(s), hive_db	hive_table_db, hive_table_columns, hive_table_partitionkeys, hive_process_process_execution, hive_process_columnlineage, hive_table_ddl_queries
ALTERVIEW_AS_SELECT	impala_process, impala_process_execution, impala_column_lineage, hive_table_ddl	Updates to: hive_table, hive_column(s)	hive_process_process_execution, hive_process_columnlineage, hive_table_ddl_queries
INSERT INTO, INSERT, OVERWRITE	impala_process, impala_process_execution	If not already in Atlas, HMS sends metadata for data assets indicated in the query: hive_table, hive_column(s), hive_storagedesc, hive_db	hive_process_process_execution

Notable actions in Impala that do NOT produce process or process execution entities in Atlas, meaning that no lineage is produced for these operations:

LOAD DATA INPATH
CREATE TABLE (table metadata produced by HMS)
ALTER VIEW (table metadata produced by HMS)
SELECT or other queries that don’t produce output
