I haven't seen your implementation, but the likely cause of your problem is either that the new parameter isn't being sent over the client protocol, or that cqlsh is ignoring it. The cqlsh output of DESCRIBE TABLE seems to be generated by the TableMetadata class in the python driver (see the as_cql_query method). Dropping a breakpoint in there would probably be a good place to start. On January 24, 2017 at 7:07:38 AM, Murukesh Mohanan (murukesh.moha...@gmail.com) wrote:
I'm having a go at CASSANDRA-13002 ( https://issues.apache.org/jira/browse/CASSANDRA-12403), by adding a new table property which will override the global slow_query_log_timeout_in_ms setting. It works, but I can't get it to show up in cqlsh DESCRIBE TABLE output. For example, this is what I get: cqlsh> DESCRIBE TABLE foo.bar; CREATE TABLE foo.bar ( id uuid PRIMARY KEY, name text ) WITH bloom_filter_fp_chance = 0.01 AND caching = {'keys': 'ALL', 'rows_per_partition': 'NONE'} AND cdc = true 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 = 1001 AND min_index_interval = 128 AND read_repair_chance = 0.0 AND speculative_retry = '99PERCENTILE'; cqlsh> select table_name, slow_query_log_timeout_in_ms from system_schema.tables where table_name = 'bar' allow filtering; table_name | slow_query_log_timeout_in_ms ------------+------------------------------ bar | 103 The property (which is also called `slow_query_log_timeout_in_ms`) shows up in the system_schema table. It seems that the file to modify would be src/java/org/apache/cassandra/db/ColumnFamilyStoreCQLHelper.java, but I didn't have any luck modifying it. Any pointers, please? -- Murukesh Mohanan, Yahoo!
