Assignee: Joseph Lynch
Reviewers: Jordan West
> Cassandra 4.0 doesn't output DESCRIBE TABLE representations that are valid
> ---------------------------------------------------------------------------
>
> Key: CASSANDRA-14822
> URL: https://issues.apache.org/jira/browse/CASSANDRA-14822
> Project: Cassandra
> Issue Type: Bug
> Components: Legacy/Tools
> Reporter: Joseph Lynch
> Assignee: Joseph Lynch
> Priority: Low
> Labels: cqlsh
>
> Looks like right now on 4.0 the {{DESCRIBE}} output of a table is no longer
> valid since {{dclocal_read_repair_chance}} was removed:
> {noformat}
> cqlsh> CREATE KEYSPACE test WITH replication = {'class': 'SimpleStrategy',
> 'replication_factor': 1};
> cqlsh> CREATE TABLE test.test (key text, value text, PRIMARY KEY(key));
> cqlsh> DESCRIBE TABLE test.test
> CREATE TABLE test.test (
> key text PRIMARY KEY,
> value text
> ) WITH 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 = 0.0
> 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 = '99p';
> {noformat}
> If you then try to copy and past that output it fails:
> {noformat}
> cqlsh> CREATE TABLE test.test2 (
> ... key text PRIMARY KEY,
> ... value text
> ... ) WITH 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':

> ... AND crc_check_chance = 1.0
> ... AND dclocal_read_repair_chance = 0.0
> ... AND default_time_to_live = 0

> SyntaxException: Unknown property 'dclocal_read_repair_chance'
> {noformat}
> Currently we leave in {{dclocal_read_repair_chance}} and
> {{read_repair_chance}} for the drivers per the comments left during
> CASSANDRA-13910.
> I think we can just ignore those parameters in the validation/creation.
