This patch clear the ambiguity in the swagger definition file and adds
the implementation for the memtable memory related methods.
For each column family there is an active memtable and a list of non
active.
when refering the all the memtable in the column family, the nick name
will contain cf_all_memtables.
Each URL has two versions, one, with a column family name, that is
relevant to a specific column family and one without, which is the
result of running the method on all column families.
This patch adds the following implementation to column_family:
get_memtable_on_heap_size
get_all_memtable_on_heap_size
get_memtable_off_heap_size
get_all_memtable_off_heap_size
get_memtable_live_data_size
get_all_memtable_live_data_size
get_all_memtables_on_heap_size
get_all_all_memtables_on_heap_size
get_all_memtables_off_heap_size
get_all_all_memtables_off_heap_size
get_all_memtables_live_data_size
get_all_all_memtables_live_data_size
Memory consumption is map this way: All memory assume to be off heap, so
on heap will return 0, and off heap will return the memory consumption
After this patch the following URL will be available:
/column_family/metrics/memtable_on_heap_size/{name}
/column_family/metrics/memtable_on_heap_size
/column_family/metrics/memtable_off_heap_size/{name}
/column_family/metrics/memtable_off_heap_size
/column_family/metrics/memtable_live_data_size/{name}
/column_family/metrics/memtable_live_data_size
/column_family/metrics/all_memtables_on_heap_size/{name}
/column_family/metrics/all_memtables_on_heap_size
/column_family/metrics/all_memtables_off_heap_size/{name}
/column_family/metrics/all_memtables_off_heap_size
/column_family/metrics/all_memtables_live_data_size/{name}
/column_family/metrics/all_memtables_live_data_size

#Urchin
##Building Urchin
In addition to required packages by Seastar, the following packages are required by Urchin.
Submodules
Urchin uses submodules, so make sure you pull the submodules first by doing:
git submodule init
git submodule update --recursive
Building urchin on Fedora
Installing required packages:
sudo yum install yaml-cpp-devel lz4-devel zlib-devel snappy-devel jsoncpp-devel thrift-devel antlr3-tool antlr3-C++-devel libasan libubsan
Building urchin on Ubuntu 14.04
Installing required packages:
sudo apt-get install libyaml-cpp-dev liblz4-dev zlib1g-dev libsnappy-dev libjsoncpp-dev
Building Fedora RPM
As a pre-requisite, you need to install Mock on your machine:
# Install mock:
sudo yum install mock
# Add user to the "mock" group:
usermod -a -G mock $USER && newgrp mock
Then, to build an RPM, run:
./dist/redhat/build_rpm.sh
The built RPM is stored in /var/lib/mock/<configuration>/result directory.
For example, on Fedora 21 mock reports the following:
INFO: Done(scylla-server-0.00-1.fc21.src.rpm) Config(default) 20 minutes 7 seconds
INFO: Results and/or logs in: /var/lib/mock/fedora-21-x86_64/result
