Oracle DBMS_HADOOP
Version 19.3

General Information
Library Note Morgan's Library Page Header
For how many years have you been working with physical servers that are starving your database of the memory necessary to deploy important new performance features such as the Result Cache, Memoptimize Pool, In-Memory Aggregation, In-Memory Column Store, and Full Database Caching? Too long? Contact me to learn how to improve all queries ... not just some queries.
Purpose Provides a PL/SQL procedure called CREATE_EXTDDL_FOR_HIVE(), that creates an Oracle external table for a given hive table. Big Data SQL needs to be correctly set up for DBMS_HADOOP to work.

Subprograms
 
CREATE_EXTDDL_FOR_HIVE
Given a hive table name, creates a text of DDL that can be executed to create an external table corresponding to the hive table dbms_hadoop.create_extddl_for_hive(
cluster_id      IN  VARCHAR2,
db_name         IN  VARCHAR2,
hive_table_name IN  VARCHAR2,
hive_partition  IN  BOOLEAN,
table_name      IN  VARCHAR2,
perform_ddl     IN  BOOLEAN,
text_of_ddl     OUT CLOB);
TBD
 
CREATE_HYBRID_PARTNED_TABLE (new 19c)
Given a LIST partitioned local Oracle table and a (list) partitioned Hive table, merge the Hive partitions into the Oracle table. The Oracle table now becomes a hybrid partitioned table. dbms_hadoop.create_hybrid_partned_table(
cluster_id      IN  VARCHAR2,
db_name         IN  VARCHAR2,
hive_table_name IN  VARCHAR2,
table_name      IN  VARCHAR2,
perform_ddl     IN  BOOLEAN := FALSE,
text_of_ddl     OUT CLOB);
TBD
 
SYNC_PARTITIONS_FOR_HIVE
Synchronizes the existing partitioning definition of a hive table in Oracle catalog dbms_hadoop.sync_partitions_for_hive(
xt_tab_name  IN VARCHAR2,
xt_tab_owner IN VARCHAR2);
TBD
 
USER_PRIVILEGED (new 19c)
Verifies whether a user has a given role dbms_hadoop.user_privileged(
user_role  IN VARCHAR2,
cluster_id IN VARCHAR2)
RETURN NUMBER;
TBD
