Laxmikant Upadhyay updated CASSANDRA-14564:
-------------------------------------------
Description:
I have upgraded my system from cassandra 2.1.16 to 3.11.2. We had some tables
with COMPACT STORAGE enabled. We see some weird behaviour of cassandra while
adding a column into it.
Cassandra does not give any error while altering however the added column is
invisible.
Same behaviour when we create a new table with compact storage and try to alter
it. Below is the commands ran in sequence:
{code:java}
x@cqlsh:xuser> CREATE TABLE xuser.employee(emp_id int PRIMARY KEY,emp_name
text, emp_city text, emp_sal varint, emp_phone varint ) WITH COMPACT STORAGE;
x@cqlsh:xuser> desc table xuser.employee ;
CREATE TABLE xuser.employee (
emp_id int PRIMARY KEY,
emp_city text,
emp_name text,
emp_phone varint,
emp_sal varint
) WITH COMPACT STORAGE
AND bloom_filter_fp_chance = 0.01
AND caching = {'keys': 'ALL', 'rows_per_partition': 'NONE'}
AND comment = ''
AND compaction = {'class':
'org.apache.cassandra.db.compaction.SizeTieredCompactionStrategy',
'max_threshold': '32', 'min_threshold': '4'}
AND compression = {'chunk_length_in_kb': '64', 'class':
'org.apache.cassandra.io.compress.LZ4Compressor'}
AND crc_check_chance = 1.0
AND dclocal_read_repair_chance = 0.1
AND default_time_to_live = 0
AND gc_grace_seconds = 864000
AND max_index_interval = 2048
AND memtable_flush_period_in_ms = 0
AND min_index_interval = 128
AND read_repair_chance = 0.0
AND speculative_retry = '99PERCENTILE';{code}
Now altering the table by adding a new column:
{code:java}
x@cqlsh:xuser> alter table employee add profile text;
x@cqlsh:xuser> desc table xuser.employee ;
CREATE TABLE xuser.employee (
emp_id int PRIMARY KEY,
emp_city text,
emp_name text,
emp_phone varint,
emp_sal varint
) WITH COMPACT STORAGE
AND bloom_filter_fp_chance = 0.01
AND caching = {'keys': 'ALL', 'rows_per_partition': 'NONE'}
AND comment = ''
AND compaction = {'class':
'org.apache.cassandra.db.compaction.SizeTieredCompactionStrategy',
'max_threshold': '32', 'min_threshold': '4'}
AND compression = {'chunk_length_in_kb': '64', 'class':
'org.apache.cassandra.io.compress.LZ4Compressor'}
AND crc_check_chance = 1.0
AND dclocal_read_repair_chance = 0.1
AND default_time_to_live = 0
AND gc_grace_seconds = 864000
AND max_index_interval = 2048
AND memtable_flush_period_in_ms = 0
AND min_index_interval = 128
AND read_repair_chance = 0.0
AND speculative_retry = '99PERCENTILE';
{code}
notice that above desc table result does not have newly added column profile.
However when i try to add it again it gives column already exist;
{code:java}
x@cqlsh:xuser> alter table employee add profile text;
InvalidRequest: Error from server: code=2200 [Invalid query] message="Invalid
column name profile because it conflicts with an existing column"
x@cqlsh:xuser> select emp_name,profile from employee;
emp_name | profile
----------+---------
(0 rows)
x@cqlsh:xuser>
{code}
Inserting also behaves strange:
{code:java}
x@cqlsh:xuser> INSERT INTO employee (emp_id , emp_city , emp_name , emp_phone ,
emp_sal ,profile) VALUES ( 1, 'ggn', 'john', 123456, 50000, 'SE');
InvalidRequest: Error from server: code=2200 [Invalid query] message="Some
clustering keys are missing: column1"
x@cqlsh:xuser> INSERT INTO employee (emp_id , emp_city , emp_name , emp_phone ,
emp_sal ,profile,column1) VALUES ( 1, 'ggn', 'john', 123456, 50000, 'SE',null);
x@cqlsh:xuser> select * from employee;
emp_id | emp_city | emp_name | emp_phone | emp_sal
