Joseph Lynch commented on CASSANDRA-14822: ------------------------------------------ Interesting, from what I can tell the [CQL spec|https://github.com/apache/cassandra/blob/trunk/doc/native_protocol_v3.spec] doesn't actually talk about how drivers are supposed to implement schema even if in practice (I think) they couple directly to the {{system}} tables. > 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 > ...
