Hi All!
I have a problem with using cassandra. Our application does a lot of
overwrites and deletes. If I understand correctly cassandra does not
actually delete these objects until gc_grace seconds have passed. I tried
to force gc by setting gc_grace to 0 on an existing column family and
running
Cassandra at least used to do disc cleanup as a side effect of
garbage collection through finalizers. (This is a mistake for the
reason outlined below.)
It is important to understand that you can *never* force* a gc in java.
Even calling System.gc() is merely a hint to the VM. What you are doing
Hello:
I'm using DataStax Enterprise 2.1, which is based on Cassandra 1.0.10 from what
I can tell. For my project, I perform a content build that generates a number
of SSTables using SSTableSimpleUnsortedWriter. These are loaded using either
JMX or sstableloader depending on the environment.
Like a lot of folks, I have a need for Big Data and fast queries on that data.
Hive queries against Cassandra functionally meet my requirements, but the job
oriented processing is too slow when you need to execute many queries on a
small portion of the data. It seems like Apache Drill might be
I don't think Drill has been accepted into the incubator yet or has any
code.
If/When that happens then it's entirely possible Cassandra could be
integrated.

In what way are the lookups failing? Is there an exception?
No exception--just failing in that the data should be there, but isn't.
At ConsistencyLevel.ONE or QUORUM?
If you are bootstrapping the node, I would expect there
