GridDB WebAPI

GridDB WebAPI is developed using GridDB Java Client and Spring Boot.

Building of the library and execution of the sample programs have been checked in the following environment.

• OS: Ubuntu 22.04(x64)
• GridDB Server: 5.9

1. Execute the command on project directory.

    $ cd webapi-ce
    $ ./gradlew build
   

   The following jar file is created.

   • webapi-ce/build/libs/griddb-webapi-ce-X.X.X.jar

2. Set the GS_WEBAPI_HOME variable for GridDB WebAPI home directory .

    $ export GS_WEBAPI_HOME=$PWD/..
   

   Default is /var/lib/gridstore/webapi.

3. Edit parameter files

    Edit the following files on the ${GS_WEBAPI_HOME}/conf directory
    - repository.json
    - griddb_webapi.properties (if necessary)
   
    When you change port (default is 8081) used in URI, please do the following steps.
    1. Copy webapi-ce/src/main/resource/application.properties to your working directory
    2. Edit server.port in it
   

4. Run with Jar

    java -jar ./build/libs/griddb-webapi-ce-X.X.X.jar
   

GridDB Server need to be started in advance.

1. Create a container

    #Request  http://[host]:[port]/griddb/v2/[clusterName]/dbs/public/containers 
    $ curl -X POST --basic -u admin:admin -H "Content-type:application/json" -d 
    '{"container_name":"test", "container_type":"COLLECTION", "rowkey":true, 
    "columns":[{"name":"col1", "type":"STRING", "index":["TREE"]}, 
      {"name":"col2", "type":"INTEGER"}, {"name":"col3", "type":"BOOL"}]}' 
    http://127.0.0.1:8081/griddb/v2/mycluster/dbs/public/containers
   

2. Append a row data

    #Request  http://[host]:[port]/griddb/v2/[clusterName]/dbs/public/containers/[containerName]/rows 
    $ curl -X PUT --basic -u admin:admin -H "Content-type:application/json" -d 
    '[["value", 1, true]]' 
    http://127.0.0.1:8081/griddb/v2/mycluster/dbs/public/containers/test/rows 
   

3. Get a row data

    #Request  http://[host]:[port]/griddb/v2/[clusterName]/dbs/public/containers/[containerName]/rows 
    $ curl -X POST --basic -u admin:admin -H "Content-type:application/json" -d 
    '{"limit":1000}'
    http://127.0.0.1:8081/griddb/v2/mycluster/dbs/public/containers/test/rows 
    --> {"columns":[{"name":"col1","type":"STRING"},{"name":"col2","type":"INTEGER"}, 
          {"name":"col3","type":"BOOL"}],"rows":[["value",1,true]],"offset":0,"limit":1000,"total":1}
   

4. Query with TQL

    #Request  http://[host]:[port]/griddb/v2/[clusterName]/dbs/public/tql 
    $ curl -X POST --basic -u admin:admin -H "Content-type:application/json" -d 
    '[{"name":"test", "stmt":"select *", "columns":[]}]' 
    http://127.0.0.1:8081/griddb/v2/mycluster/dbs/public/tql 
    --> [{"columns":[{"name":"col1","type":"STRING"},{"name":"col2","type":"INTEGER"}, 
           {"name":"col3","type":"BOOL"}],"results":[["value",1,true]],"offset":0,"limit":1000000,"total":1}]
   

5. Query with SQL

    #Request  http://[host]:[port]/griddb/v2/[clusterName]/dbs/public/sql/select 
    $ curl -X POST -u admin:admin -H "Content-type:application/json; charset=UTF-8" 
    -d '[{"stmt":"select * from test"}]' 
    http://127.0.0.1:8081/griddb/v2/mycluster/dbs/public/sql/dml/query 
    --> [{"columns":[{"name":"col1","type":"STRING"},{"name":"col2","type":"INTEGER"}, 
           {"name":"col3","type":"BOOL"}],"results":[["value",1,true]]}]
   
    Note: "/:cluster/dbs/:database/sql/select" style is not recommended.
   

6. Update with SQL

    #Request  http://[host]:[port]/griddb/v2/[clusterName]/dbs/public/sql/update 
    $ curl -X POST -u admin:admin -H "Content-type:application/json; charset=UTF-8" 
    -d '[{"stmt":"update test set col3 = false where col2 = 1"}]' 
    http://127.0.0.1:8081/griddb/v2/mycluster/dbs/public/sql/dml/update 
    --> [{"status":1, "updatedRows":1,
           "stmt":"update test set col3 = false where col2 = 1", "message":null}]
   
    Note: "/:cluster/dbs/:database/sql/update" style is not recommended.
