License OpenIssue ClosedIssue Stars Forks

中文

CeresDB is a high-performance, distributed, schema-less, cloud native time-series database that can handle both time-series and analytics workloads.

Status

The project is currently under rapid development. This early stage is not production ready and may incur data corruptions.

RoadMap

See our RoadMap

Get started

Clone the repository

Clone this repository by git and enter it:

git clone [email protected]:CeresDB/ceresdb.git
cd ceresdb

Run ceresdb in docker

Ensure that docker is installed in your development environment, and then build the image with the provided Dockerfile:

docker build -t ceresdb .

Start the ceresdb container using the built docker image:

docker run -d -t --name ceresdb -p 5440:5440 -p 8831:8831 ceresdb

Compile and run CeresDB

Install dependencies

In order to compile CeresDB, some relevant dependencies(including Rust toolchain) should be installed.

Dependencies(Ubuntu20.04)

Assuming the development environment is Ubuntu20.04, execute the following command to install the required dependencies:

apt install git curl gcc g++ libssl-dev pkg-config cmake

It should be noted that the compilation of the project actually has version requirements for some dependencies such as cmake, gcc, g++, etc. If your development environment is an old Linux distribution, it is necessary to manually install these dependencies of a higher version.

Rust

Rust can be installed by rustup. After installing rustup, when entering the CeresDB project, the specified Rust version will be automatically downloaded according to the rust-toolchain file.

After execution, you need to add environment variables to use the Rust toolchain. Basically, just put the following commands into your ~/.bashrc or ~/.bash_profile:

source $HOME/.cargo/env

Compile and run

Compile CeresDB by the following command:

cargo build --release

Then you can run CeresDB using the default configuration file provided in the codebase.

./target/ceresdb-server --config ./docs/example.toml

Write and read data

CeresDB supports custom extended SQL protocol. Currently, you can create tables and read/write data with SQL statements through http service.

Create table

curl --location --request POST 'http://127.0.0.1:5440/sql' \
--header 'Content-Type: application/json' \
--data-raw '{
    "query": "CREATE TABLE `demo` (`name` string TAG, `value` double NOT NULL, `t` timestamp NOT NULL, TIMESTAMP KEY(t)) ENGINE=Analytic with (enable_ttl='\''false'\'');"
}'

Write data

curl --location --request POST 'http://127.0.0.1:5440/sql' \
--header 'Content-Type: application/json' \
--data-raw '{
    "query": "INSERT INTO demo(t, name, value) VALUES(1651737067000, '\''ceresdb'\'', 100)"
}'

Read data

curl --location --request POST 'http://127.0.0.1:5440/sql' \
--header 'Content-Type: application/json' \
--data-raw '{
    "query": "select * from demo"
}'

Show create table

curl --location --request POST 'http://127.0.0.1:5440/sql' \
--header 'Content-Type: application/json' \
--data-raw '{
    "query": "show create table demo"
}'

Drop table

curl --location --request POST 'http://127.0.0.1:5440/sql' \
--header 'Content-Type: application/json' \
--data-raw '{
    "query": "DROP TABLE demo;"
}'

  • feat: support show database and show tables

    feat: support show database and show tables

    Which issue does this PR close?

    Closes #66

    Rationale for this change

    What changes are included in this PR?

    In order to satisfy the current three Show statements: show create table, show tables and show database, I modified the Plan part where show create table is located and combined it into a ShowPlan.

    Are there any user-facing changes?

    For users, two new sql statements are added to find schema and table in ceresDB.

    Effect

    SHOW TABLES

    First, use show tables to view existing tables: show tables; image Next, use create table sql to create a new table:

    CREATE TABLE `hello_show` (`name` string TAG, `value` double NOT NULL, `t` timestamp NOT NULL, TIMESTAMP KEY(t)) ENGINE=Analytic with (enable_ttl='false');
    

    image Last view effect show tables; image

    SHOW DATABASE

    exec show database; image

    How does this change test

    add 2 unit test:

    1. test_show_tables_statement_to_plan
    2. test_show_database_statement_to_plan

  • feat: add mysql server support

    feat: add mysql server support

    Which issue does this PR close?

    Closes #43

    Rationale for this change

    Convenient for mysql client to use

    What changes are included in this PR?

    • [x] add mysql server structure
    • [x] implement sql execute

    Are there any user-facing changes?

    there are user-facing changes that needs to update the documentation or configuration.

    a new configuration items have been added to the server::config.rs file:

    1. mysql_port: the mysql server listening port, default 3307

    How does this change test

    todo

    Note

    what I tried at first was opensrv, but I am not very proficient in tokio and related concurrent operations. since ceresDB needs to pass in Instance<C, Q> when executing sql, when I try to use AsyncMysqlIntermediary to run the service, I am troubled by the asynchrony of these two generic types. It requires me to declare the specific types of C and Q, such as: impl<C: Catalog, Q: Query>, but in this case, the server.rs needs to be changed to this:

    pub struct Server<C: Catalog, Q: Query> {
        http_service: Service<C, Q>,
        rpc_services: RpcServices,
        mysql_service: mysql::MysqlHandler<C, Q>,
    }
    

    I think this modification is not very good, so I finally use msql-srv

    How to use it?

    First, we can start ceresdb as usual. We can see that there is an extra entry in the startup log:

    2022-06-22 21:16:10.980 INFO [server/src/mysql/handler.rs:54] Mysql service listens on 127.0.0.1:3307
    

    Mysql service starts on port 3307 by default, you can customize it by modifying the ·mysql_port· option in the configuration file

    Next, you should install a mysql-client and connect to mysql by typing:

    mysql -P3307 -h127.0.0.1
    

    We will enter the mysql console. image

    Finally, Use ceresdb like mysql.

    Example

    Create table

    CREATE TABLE `hello_mysql` (`name` string TAG, `value` double NOT NULL, `t` timestamp NOT NULL, TIMESTAMP KEY(t)) ENGINE=Analytic with (enable_ttl='false');
    

    image

    Write data

    INSERT INTO hello_mysql(t, name, value) VALUES(1651737067000, 'ceresdb', 100);
    

    image

    Read data

    select * from hello_mysql;
    

    image

    Show create table

    show create table hello_mysql;
    

    image

    Drop table

    DROP TABLE hello_mysql;
    

    image

  • Query fields are sorted by creation

    Query fields are sorted by creation

    Description ceresDB doesn't seem to require strict ordering of query result fields.

    Proposal

    Use the order in which fields are created.

    Additional context

    when I create table use:

    CREATE TABLE `hello_mysql` (`name` string TAG, `value` double NOT NULL, `t` timestamp NOT NULL, TIMESTAMP KEY(t)) ENGINE=Analytic with (enable_ttl='false');
    

    and select it. his field order seems to be random? I found that the query result is wrapped in HashMap. image

    This doesn't seem to have any effect on normal usage, so I don't know if this situation needs improvement.

  • Integration tests are not stable

    Integration tests are not stable

    Describe this problem

    For create table test,

    https://github.com/CeresDB/ceresdb/blob/25557c73adaa6815875aaea3ccd5b61bf54e291f/tests/cases/local/05_ddl/create_tables.sql#L64

    it will report error like:

    Failed to execute query, err: Server(ServerError { code: 500, msg: "Failed to execute interpreter, query: CREATE TABLE `05_create_tables_t8`(c1 int, t1 timestamp NOT NULL TIMESTAMP KEY) ENGINE = Analytic with (storage_format= 'unknown');. Caused by: Failed to execute create table, err:Failed to create table, name:05_create_tables_t8, err:Failed to create table, err:Invalid arguments, err:Invalid options, space_id:2, table:05_create_tables_t8, table_id:2199023255725, err:Unknown storage format. value:\"unknown\"." })
    

    The table_id in error message is not stable in my local pc, it will change if I run tests again.

    The issue maybe is in test config, we use Local storage as the server config for integration tests now.

    Steps to reproduce

    Run tests again.

    Expected behavior

    The output should the same as before when we rerun tests.

  • Column order is not what user define when create table

    Column order is not what user define when create table

    Describe this problem

    Table' columns order is not what user define when create table

    Steps to reproduce

    Execute those SQL

    CREATE TABLE test_order (
        host string tag,
        v2 int,
        ts timestamp NOT NULL,
        v1 int,

    desc test_order;
    

    desc will output

    ts	timestamp	1	0	0
    tsid	uint64	1	0	0
    host	string	0	1	1
    v1	int	0	1	1
    v2	int	0	1	0
    

    Expected behavior

    The column order should be same with the order when created.

    The root cause is currently we use a BTreeMap when build create table plan, it should use a vector to keep the ordering

  • Simplify SQL syntax that specifies timestamp key column

    Simplify SQL syntax that specifies timestamp key column

    Description

    TIMESTAMP KEY is a special column in analytic engine. It need to be set to a column with Timestamp type and with NOT NULL constrain.

    CREATE TABLE demo (
        name string TAG,
        value double NOT NULL,
        t timestamp NOT NULL,
        TIMESTAMP KEY(t)
    ) ENGINE=Analytic;
    

    It must have one and only one TIMESTAMP KEY column in a table.

    Proposal there are a few ways to simplify it.


    • Specify TIMESTAMP KEY without create a column Considering the constraints, user is actually giving a name to the TIMESTAMP KEY column.
    CREATE TABLE demo (
        name string TAG,
        value double NOT NULL,
        TIMESTAMP KEY(t)
    ) ENGINE=Analytic;
    

    • Move TIMESTAMP KEY to column definition. This makes TIMESTAMP KEY act like primary key.
    CREATE TABLE demo (
        name string TAG,
        value double NOT NULL,
        t timestamp NOT NULL TIMESTAMP KEY
    ) ENGINE=Analytic;
    

    • Do not need to define it and let CeresDB infers the TIMESTAMP KEY Allow user to not specify TIMESTAMP KEY in create table SQL. CeresDB will try to find a column with Timestamp type and NOT NULL. Report error if zero or multiple columns are found.
    CREATE TABLE demo (
        name string TAG,
        value double NOT NULL,
        t timestamp NOT NULL
    ) ENGINE=Analytic;
