Hello guys, I have a cassandra cluster 2.1 comprised of 4 nodes.
I removed a lot of data in a Column Family, then I ran manually a compaction on this Column family on every node. After doing that, If I query that data, cassandra correctly says this data is not there. But the space on disk is exactly the same before removing that data. Also, I realized that gc_grace_seconds = 0. Some people on the internet say that it could produce zombie data, what do you think? I do not have a TTL defined on the Column family, and I do not have the possibility to create it. So my questions is, given that I do not have a TTL defined is data going to be removed? or the deleted data is never actually going to be deleted due to I do not have a TTL? Thanks in advance! -- Saludos / Regards. Analía Lorenzatto. “It's possible to commit no errors and still lose. That is not weakness. That is life". By Captain Jean-Luc Picard.
