我是Cassandra的新手,我試圖刪除記錄時遇到了一些問題。我有一個表定義如下:Cassandra刪除記錄
CREATE TABLE wire_journal (
persistence_id text,
partition_nr bigint,
sequence_nr bigint,
timestamp timeuuid,
timebucket text,
event blob,
event_manifest text,
message blob,
ser_id int,
ser_manifest text,
tag1 text,
tag2 text,
tag3 text,
used boolean static,
writer_uuid text,
PRIMARY KEY ((persistence_id, partition_nr), sequence_nr, timestamp, timebucket)
) WITH CLUSTERING ORDER BY (sequence_nr ASC, timestamp ASC, timebucket ASC)
AND bloom_filter_fp_chance = 0.01
AND caching = {'keys': 'ALL', 'rows_per_partition': 'NONE'}
AND comment = ''
AND compaction = {'bucket_high': '1.5', 'bucket_low': '0.5', 'class': 'org.apache.cassandra.db.compaction.SizeTieredCompactionStrategy', 'enabled': 'true', 'max_threshold': '32', 'min_sstable_size': '50', 'min_threshold': '4', 'tombstone_compaction_interval': '86400', 'tombstone_threshold': '0.2', 'unchecked_tombstone_compaction': 'false'}
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 = 0
AND min_index_interval = 128
AND read_repair_chance = 0.0
AND speculative_retry = '99PERCENTILE';
和索引的定義如下:
CREATE CUSTOM INDEX timestamp_idx ON wire_journal (timestamp) USING 'org.apache.cassandra.index.sasi.SASIIndex';
CREATE CUSTOM INDEX manifest_idx ON wire_journal (event_manifest) USING 'org.apache.cassandra.index.sasi.SASIIndex';
我希望能夠通過時間戳和event_manifest刪除。
我可以通過一個事件清單,例如查詢:
select event_manifest, dateOf(timestamp) from wire_journal where event_manifest = '011000028';
上述作品查詢。但是如果我嘗試了同樣的標準做了刪除如下:
delete from wire_journal where event_manifest = '011000028';
我收到以下錯誤:
InvalidRequest:代碼= 2200 [無效查詢]消息=「一些分區關鍵零部件缺失:persistence_id,partition_nr」
我試過,包括在我刪除這些列如下:
delete persistence_id, partition_nr from wire_journal where event_manifest = 'aba:011000028';
,我得到了以下錯誤:
invalidRequest:代碼= 2200 [無效查詢]消息=「無效標識符persistence_id刪除(不應該是一個PRIMARY KEY部分)」
我怎麼能去刪除了全部符合條件的記錄?
