Im运行Cassandra版本2.1.2和cqlsh 5.0.1
这是weather.log表，weather是具有一致性级别一的keyspace。我配置了2个节点。
CREATE KEYSPACE weather WITH replication = {'class': 'NetworkTopologyStrategy', 'us-east': '1'} AND durable_writes = true;
CREATE TABLE weather.log (
ip inet,
ts timestamp,
city text,
country text,
PRIMARY KEY (ip, ts)
) WITH CLUSTERING ORDER BY (ts DESC)
AND bloom_filter_fp_chance = 0.01
AND caching = '{"keys":"ALL", "rows_per_partition":"NONE"}'
AND comment = ''
AND compaction = {'min_threshold': '4', 'class': 'org.apache.cassandra.db.compaction.SizeTieredCompactionStrategy', 'max_threshold': '32'}
AND compression = {'sstable_compression': 'org.apache.cassandra.io.compress.LZ4Compressor'}
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 = '99.0PERCENTILE';
当我们运行查询时。
select distinct ip from weather.log
我们得到了不一致、错误的回应。一旦我们得到99，下次我们得到1600等[实际数字应该>2000]
我也尝试过将一致性级别设置为ALL的查询。它有力量工作。
为什么会发生这种情况？我需要拿到所有的钥匙。如何获取所有主键？
看起来您可能受到CASSANDRA-8940的影响。我建议更新到最新的2.1.x版本，并验证此问题是否已为您修复。
