Re : Compressed families not created on new node

The I/O errors are caused by disk failure. Syslog contains some of those things: Jan 16 09:53:24 --- kernel: [7065781.460804] sd 4:0:0:0: [sda]  Add. Sense: Unrecovered read error Jan 16 09:53:24 --- kernel: [7065781.460810] sd 4:0:0:0: [sda] CDB: Read(10): 28 00 11 cf 60 70 00 00 08 00 Jan 16

Configuring leveled compaction

Its technically possible to have without breaking basic levelDB algorithm configurable sstable size and count on different levels? something like: level 1 - 10 x 50 MB tables level 2 - 60 x 40 MB tables level 3 - 150 x 30 MB tables I am interested in more deeper leveldb research, because curre

RE: JMX BulkLoad weirdness

Unfortunately, I'm not doing a 1-1 migration; I'm moving data from a 15-node to a 6-node cluster. In this case, that means an excessive amount of time spent repairing data put on to the wrong machines. Also, the bulkloader's requirement of having either a different IP address or a different mac

Re: nodetool ring question
