Wasil Shaikh created CASSANDRA-14622: ----------------------------------------
Summary: Run compaction on cluster Key: CASSANDRA-14622 URL: https://issues.apache.org/jira/browse/CASSANDRA-14622 Project: Cassandra Issue Type: Bug Components: CQL Environment: CentOS Linux release 7.1.1503 (Core) Reporter: Wasil Shaikh Fix For: 2.2.1 Dear Team, I have setup a cassandra cluster for 3 m/c. [root@ip-172-31-21-222 ~]# nodetool status Datacenter: datacenter1 ======================= Status=Up/Down |/ State=Normal/Leaving/Joining/Moving -- Address Load Tokens Owns Host ID Rack UN 172.31.21.223 4.01 TB 256 ? 9d2a408a-264f-423f-8af2-e1d4cb608998 rack1 UN 172.31.21.222 4.5 TB 256 ? c3d24437-3e03-41d7-a2af-2ed53bcf2dfc rack1 UN 172.31.21.221 4.26 TB 256 ? aaf4fbaf-837b-44e2-98ba-5eb2b3e6b62b rack1 Note: Non-system keyspaces don't have the same replication settings, effective ownership information is meaningless [root@ip-172-31-21-222 ~]# Now i have deleted around 40-45 GB data but space seems is not vacant. I'm using SizeTieredCompactionStrategy and below is my table defination. CREATE TABLE test.att_103 ( md5 text PRIMARY KEY, arcsize int, att_str blob, attsize int, udate timestamp ) 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'} 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'; I have dumped data using sstable2json command to verify whether my column data is deleted or not. e.g {"key": "9b7937de43aa22fc3bf18ec72d86140b", "cells": [["att_str",1533305633,1533305633552000,"d"], ["udate","2018-08-03 14:13Z",1533305633552000]]} Now can you help me here regarding how to run compaction manually instead of waiting for 10 days of grace period.
