It seems there is a dependancy on libjets3t-java
Is it really needed ? This dependancy cannot be resolved on Ubuntu Lucid :-(
Hi,
We are testing Cassandra here, we would like to use it to store some data :
- about 1000 inserts / seconds in a CF "RAW" :
Column : TimeUUID (timeuuid of the insert, so 1000 new columns / second)
Row : MMDDHH of the insert (to minimize the size of rows, the biggest
one is 2GB data),
Hi,
Thank you for your help.
I don't know if data is writing too fast to the cluster, but I don't think so
(nodes are heavy, big CPU, 12GB RAM...) and there is no so much data (2000
inserts/sec for about 300 KB/sec of raw data).
I trashed all data yesterday 6pm (GMT+2) and launched all again.

Here is my test code :
ColumnPath new_col;
new_col.__isset.column = true; /* this is required! */
new_col.column_family.assign("Incoming");
new_col.column.assign("1968ec4a-2a73-11df-9aca-00012e27a270");
client.insert("MyKeyspace", "somekey", new_col, "Random Value", time(NULL),
ONE);
I didn't fo
w_col, "Random Value",
time(NULL), ONE);
This works, except that sometimes, there are \0 bytes in uuid, so to
column.assign get a string shorter than 16 bytes...
My question is : how could I attribute the 16 bytes of uuid to column
without using a string ? :)
Cheers,
Olivier
