Brandon Williams reassigned CASSANDRA-5766:
-------------------------------------------
Assignee: Aleksey Yeschenko
> The output of the describe command does not necessarily give you the right
> DDL to re-create the CF
> --------------------------------------------------------------------------------------------------
>
> Key: CASSANDRA-5766
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5766
> Project: Cassandra
> Issue Type: Bug
> Components: Tools
> Affects Versions: 2.1
> Reporter: Steven Lowenthal
> Assignee: Aleksey Yeschenko
>
> If compression is not set for a CF, cqlsh omits the compression attribute.
> When you replay that very same DDL, you get a CF with Snappy compression.
> This may occur with other parameters. Perhaps describe should always show
> every parameter in full. The absence of a setting is a setting. (Think of
> the arrow in the FedEx logo).
> Create a CF with cassandra-stress. cassandra-stress defaults to NO
> compression.
> ~/dse/resources/cassandra/tools/bin/cassandra-stress -S 100 -c 1 --num-keys 1
> describe it
> CREATE TABLE "Standard1" (
> key blob PRIMARY KEY,
> "C0" blob
> ) WITH COMPACT STORAGE AND
> bloom_filter_fp_chance=0.010000 AND
> caching='KEYS_ONLY' AND
> comment='' AND
> dclocal_read_repair_chance=0.000000 AND
> gc_grace_seconds=864000 AND
> read_repair_chance=0.100000 AND
> replicate_on_write='true' AND
> populate_io_cache_on_flush='false' AND
> compaction={'class': 'SizeTieredCompactionStrategy'};
> replay it - I changed the cf name to standard2
> describe the new CF:
> CREATE TABLE standard2 (
> key blob PRIMARY KEY,
> "C0" blob
> ) WITH COMPACT STORAGE AND
> bloom_filter_fp_chance=0.010000 AND
> caching='KEYS_ONLY' AND
> comment='' AND
> dclocal_read_repair_chance=0.000000 AND
> gc_grace_seconds=864000 AND
> read_repair_chance=0.100000 AND
> replicate_on_write='true' AND
> populate_io_cache_on_flush='false' AND
> compaction={'class': 'SizeTieredCompactionStrategy'} AND
> compression={'sstable_compression': 'SnappyCompressor'};
