This series introduces a cache of already authenticated prepared statements which
is meant to optimize the prepared statement lookup when authentication is enabled.
This cache allows to perform a single cache lookup per EXECUTE operation as opposed
to at least 2 lookups: one in the prepared statements cache and one in the authentication
cache.
Tests:
- cql_query_test {debug, release}.
- cassandra-stress with authentication enabled and with short eviction timeout.
- Manual (with printouts) checks:
- Tested the eviction due to eviction in the prepared_statements_cache:
- Artificially decreased the prepared_statements_cache size and ran c-s with different keyspaces.
- Verified that the corresponding authorized_prepared_statements_cache entry is evicted and re-populated.
- Tested the BATCH of prepared statements (with dtest infrastructure):
- Verified that for each prepared statement authorized_prepared_statements_cache is updated only once:
- The batch contained a few entries of the same prepared statement.
"
* 'authorized_prepared_statements_cache-v3' of https://github.com/vladzcloudius/scylla:
cql3: use authorized_prepared_statements_cache in the BATCH processing
cql3::statements::batch_statement: introduce a single_statement class
cql3: introduce the authorized_prepared_statements_cache class
loading_shared_values: introduce the templated find() overload
tests: loading_cache_test: add a tests for a loading_cache::remove(key)/remove(iterator)
utils::loading_cache: add remove(key)/remove(iterator) methods
cql3::query_processor: properly stop() prepared_statements_cache object
Scylla
Quick-start
$ git submodule update --init --recursive
$ sudo ./install-dependencies.sh
$ ./configure.py --mode=release
$ ninja-build -j4 # Assuming 4 system threads.
$ ./build/release/scylla
$ # Rejoice!
Please see HACKING.md for detailed information on building and developing Scylla.
Running Scylla
- Run Scylla
./build/release/scylla
- run Scylla with one CPU and ./tmp as data directory
./build/release/scylla --datadir tmp --commitlog-directory tmp --smp 1
- For more run options:
./build/release/scylla --help
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
Building Fedora-based Docker image
Build a Docker image with:
cd dist/docker
docker build -t <image-name> .
Run the image with:
docker run -p $(hostname -i):9042:9042 -i -t <image name>
