"This patch series adds CQL front-end support for secondary indices. You can now execute CREATE INDEX and DROP INDEX statements, which will update the newly added "Indexes" system table. However, the indexes are not actually backed up by anything nor are they available for CQL queries. The feature is hidden behind a new cluster feature flag and enabled only with the "--experimental" flag." * 'penberg/cql-2i/v2' of github.com:cloudius-systems/seastar-dev: (34 commits) schema: Kill index_type enum schema: Kill index_info class cql3/statements/create_index_statement: Use database::existing_index_names() in validation cql3/statements: Use secondary index manager in alter_table_statement class index: Add secondary_index_manager thrift/handler: Use index_metadata db/schema_tables: Index persistence schema: Add all_indices() to schema class schema: Remove add_default_index_names() from schema_builder class db/schema_tables: Add system table for indices cql3/Cgl.g: DROP INDEX cql3/statements: Add drop_index_statement class database: Add find_indexed_table() to database class cql3: Return change event from announce_migration() cql3/statements: Multiple index targets for CREATE INDEX cql3/statements: Use index_metadata in create_index_statement class cql3/statements: Use feature flag in create_index_statement class service/storage_service: Add feature flag for secondary indices database: Add get_available_index_name() to database class schema: Add get_default_index_name() to index_metadata class ...
Scylla
Building Scylla
In addition to required packages by Seastar, the following packages are required by Scylla.
Submodules
Scylla uses submodules, so make sure you pull the submodules first by doing:
git submodule init
git submodule update --init --recursive
Building and Running Scylla on Fedora
- Installing required packages:
sudo dnf install yaml-cpp-devel lz4-devel zlib-devel snappy-devel jsoncpp-devel thrift-devel antlr3-tool antlr3-C++-devel libasan libubsan gcc-c++ gnutls-devel ninja-build ragel libaio-devel cryptopp-devel xfsprogs-devel numactl-devel hwloc-devel libpciaccess-devel libxml2-devel python3-pyparsing lksctp-tools-devel protobuf-devel protobuf-compiler systemd-devel libunwind-devel
- Build Scylla
./configure.py --mode=release --with=scylla --disable-xen
ninja-build build/release/scylla -j2 # you can use more cpus if you have tons of RAM
- 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>
