What is LinDB?

LinDB is an open-source Time Series Database which provides high performance, high availability and horizontal scalability.

LinDB stores all monitoring data of ELEME Inc, there is 88TB incremental writes per day and 2.7PB total raw data.

  • High performance

    LinDB takes a lot of best practice of TSDB and implements some optimizations based on the characteristics of time series data. Unlike writing a lot of Continuous-Query for InfluxDB, LinDB supports rollup in specific interval automatically after creating the database. Moreover, LinDB is extremely fast for parallel querying and computing of distributed time series data.

  • Multi-Active IDCs native

    LinDB is designed to work under a Multi-Active IDCs cloud architecture. The compute layer of LinDB, called brokers, supports efficient Multi-IDCs aggregation query.

  • High availability

    LinDB uses the ETCD cluster to ensure the meta-data is highly available and safely stored. In the event of failure, the Multi-channel replication protocol of WAL will avoid the problem of data inconsistency:

    1). Only one person in each replication channel is responsible for the authority of the data, so the conflicts will not happen;

    2). Data reliability is guaranteed: as long as the data that has not been copied in the old leader is not lost, it will be copied to other replication while the old leader is online again;

  • Horizontal scalability

    Series(Tags) based sharding strategy in LinDB solves the hotspots problem, and is truly horizontally expanded available by simply adding new broker and storage nodes.

  • Governance capability of metrics

    To ensure the robustness of the system, LinDB do not assume that users has understood the best practices of using metrics, therefore, LinDB provides the ability of restricting unfriendly user based on metric granularity and tags granularity.

State of this project

The current develop branch is unstable and is not recommended for production use. LinDB 0.1(what will be the first release version) is currently in the development stage. Additional features will arrive during July and August, we will translate the JAVA version of LinDB currently used under the production environment to Golang as soon as possible. The GO version is not only a simple translation of the JAVA version, but has been redesigned in many aspects.

Once we implement the final feature and replace the LinDB under production environment with the Golang version, LinDB 0.1.0 will be released. At that point, we will move into the stable phase, our intention is to avoid breaking changes to the API and storage file format.

Build

Prerequisites

To build LinDB from source you require the following on your system.

Setup environment

Export GO path and system PATH to your environment. GOPATH typically defaults to $HOME/go.

# Add these to your ~/.bashrc or ~/.bash_profile file and save file.
export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin

# Source bashrc to export to environment
$ source ~/.bashrc

Get the code

git clone https://github.com/lindb/lindb.git
cd lindb

Build from source

To build only LinDB core.(without web console)

make build

To build both LinDB core and frontend.

make build-all

Test

make test

Access web interface(for developer)

Start the node.js app to view LinDB web interface.

cd web
yarn start

You can access the LinDB web interface on your localhost port 3000

Deploy

LinDB can be deployed in both cluster mode and standalone mode.

Standalone mode

You can try out fully functional LinDB on your local system via the standalone mode. In standalone mode LinDB will be deployed with embedded broker, storage and etcd.

./bin/lind standalone init-config
./bin/lind standalone run

Make sure that the binary file is built from make build-all You can access the LinDB web console on your localhost port 9000

Cluster mode (todo)

Contributing

Contributions are welcomed and greatly appreciated. See CONTRIBUTING for details on submitting patches and the contribution workflow.

CI

Pull requests should be appropriately labeled, and linked to any relevant bug or feature tracking issues. All pull requests will run through GITHUB-Actions. Community contributors should be able to see the outcome of this process by looking at the checks on their PR and fix the build errors.

Static Analysis

This project uses the following linters. Failure during the running of any of these tools results in a failed build. Generally, code must be adjusted to satisfy these tools.

  • gofmt - Gofmt checks whether code was gofmt-ed. By default this tool runs with -s option to check for code simplification;
  • golint - Golint differs from gofmt. Gofmt reformats Go source code, whereas golint prints out style mistakes;
  • goimports - Goimports does everything that gofmt does. Additionally it checks unused imports;
  • errcheck - Errcheck is a program for checking for unchecked errors in go programs. These unchecked errors can be critical bugs in some cases;
  • gocyclo - Computes and checks the cyclomatic complexity of functions;
  • maligned - Tool to detect Go structs that would take less memory if their fields were sorted;
  • dupl - Tool for code clone detection;
  • goconst - Finds repeated strings that could be replaced by a constant;
  • gocritic - The most opinionated Go source code linter;

    Request an explanation for project name

    请问"LinDB("Lin" stands for wisdom in Shanghainese)"是否表明此项目受到了上海市政府支持或财政资助?如果不是,希望此项目不再包含地域性指向。

    如果作者看到别的开源软件声称其名字的含义是“美国人的智慧”“北京人的智慧”“海淀人的智慧”难道不会认为这样太自负了吗?

    作者若称此项目是wisdom in ELEME那自然无可指摘,因为ELEME为本项目的产生创造了条件、提供了便利,是利益共同体。但作者把“上海人的智慧”捆绑进来,我认为作者需要解释一下,为什么把上海人的智慧和其他地区人民的智慧区别开?为什么冠上“上海”的名字?我能想到的唯一可能就是此项目和上海市政府有关。涉及行政区的名称,一定是名副其实,或者体现国家意志(比如军舰)。

    如果作者认为我在抬杠,我只能说如果想抬杠我会推动其他项目以“朝阳人的智慧”命名,并来这里讲上海人的智慧不如朝阳人的智慧。

    我很抱歉这个issue比较政治化,希望作者注意到:为项目起名字时不要令人有地方主义的联想。

    Bump actions/setup-node from 1 to 3

    Bumps actions/setup-node from 1 to 3.

    Release notes

    Sourced from actions/setup-node's releases.

    Add support for asdf format and update actions/cache version to 3.0.0

    In scope of this release we updated actions/cache package as the new version contains fixes for caching error handling. Moreover, we added support for asdf format as Node.js version file actions/setup-node#373. Besides, we introduced new output node-version and added npm-shrinkwrap.json to dependency file patterns: actions/setup-node#439

    Update actions/cache version to 2.0.2

    In scope of this release we updated actions/cache package as the new version contains fixes related to GHES 3.5 (actions/setup-node#460)

    v3.0.0

    In scope of this release we changed version of the runtime Node.js for the setup-node action and updated package-lock.json file to v2.

    Breaking Changes

    Fix logic of error handling for npm warning and uncaught exception

    In scope of this release we fix logic of error handling related to caching (actions/setup-node#358) and (actions/setup-node#359).

    In the previous behaviour we relied on stderr output to throw error. The warning messages from package managers can be written to the stderr's output. For now the action will throw an error only if exit code differs from zero. Besides, we add logic to сatch and log unhandled exceptions.

    Adding Node.js version file support

    In scope of this release we add the node-version-file input and update actions/cache dependency to the latest version.

    Adding Node.js version file support

    The new input (node-version-file) provides functionality to specify the path to the file containing Node.js's version with such behaviour:

    • If the file does not exist the action will throw an error.
    • If you specify both node-version and node-version-file inputs, the action will use value from the node-version input and throw the following warning: Both node-version and node-version-file inputs are specified, only node-version will be used.
    • For now the action does not support all of the variety of values for Node.js version files. The action can handle values according to the documentation and values with v prefix (v14)
    steps:
      - uses: actions/[email protected]
      - name: Setup node from node version file
        uses: actions/[email protected]
        with:
          node-version-file: '.nvmrc'
      - run: npm install
      - run: npm test
    

    Update actions/cache dependency to 1.0.8 version.

    We updated actions/cache dependency to the latest version (1.0.8). For more information please refer to the toolkit/cache.

    Add "cache-hit" output

    This release introduces a new output: cache-hit (#327).

    The cache-hit output contains boolean value indicating that an exact match was found for the key. It shows that the action uses already existing cache or not. The output is available only if cache is enabled.

    Support caching for mono repos and repositories with complex structure

    This release introduces dependency caching support for mono repos and repositories with complex structure (#305).

    By default, the action searches for the dependency file (package-lock.json or yarn.lock) in the repository root. Use the cache-dependency-path input for cases when multiple dependency files are used, or they are located in different subdirectories. This input supports wildcards or a list of file names for caching multiple dependencies.
