Timestamp Primary key Kudu

Question

I am trying to load data into Kudu table through envelope. One of the primary key column is timestamp. DDL : CREATE TABLE BAL ( client_id int bal_id int, effective_time timestamp, prsn_id int, bal_amount double, prsn_name string, PRIMARY KEY (client_id, bal_id, effective_time) ) PARTITION BY HASH(client_id) PARTITIONS 8 STORED AS KUDU;

But It is throwing error Java.lang.illelegalArgumentException

So my question is simple - timestamp column could be part of primary key or not??

Yes it is perfectly alright to include timestamp as part of primary key. Please find the code:

use ${var:db_name};
CREATE TABLE test (
  table_name STRING NOT NULL ENCODING AUTO_ENCODING COMPRESSION DEFAULT_COMPRESSION,
  table_id BIGINT NOT NULL ENCODING AUTO_ENCODING COMPRESSION DEFAULT_COMPRESSION,
  last_read_timestamp TIMESTAMP NOT NULL ENCODING AUTO_ENCODING COMPRESSION DEFAULT_COMPRESSION,
  window STRING NOT NULL ENCODING AUTO_ENCODING COMPRESSION DEFAULT_COMPRESSION,
  ext_gen_timestamp timestamp NOT NULL ENCODING AUTO_ENCODING COMPRESSION DEFAULT_COMPRESSION,
  extract_date timestamp NOT NULL ENCODING AUTO_ENCODING COMPRESSION DEFAULT_COMPRESSION,
  manual_rerun STRING NULL ENCODING AUTO_ENCODING COMPRESSION DEFAULT_COMPRESSION,
  PRIMARY KEY (table_name, table_id, last_read_timestamp)
)
STORED AS KUDU;
