[senthuran16]

Description:
Way to configure System parameters of a Siddhi extension in the deployment.yaml file is not documented.
eg:
For configuring host & port system parameters of tcp extension, the following has to be added in SPHOME/conf/worker/deployment.yaml

siddhi: 
  extensions: 
    - extension: 
        name: tcp
        namespace: source
        properties: 
          host: 0.0.0.0
          port: 5511

@RukshiW Please do the following corrections.

1. Step3 should be changed as,

siddhi:
    extensions:
        - extension:

(The - in front of extension is missing)

2. Step 4 says "The archetypes of extensions supported are execution, io, map, script and store". source and sink are also supported (Usage of source is shown in Example 1).

3. Example 2 should be,

siddhi:
  extensions:
    - extension:
        name: rdbms

(- in front of extension)

Did the corrections mentioned in the previous comment by senthuran16.

@RukshiW Please re-indent Example 2 as:

siddhi:
  extensions:
    - extension:
        name: rdbms
        namespace: store
        properties:
          mysql.batchEnable: true
          mysql.batchSize: 1000
          mysql.indexCreateQuery: "CREATE INDEX {{TABLE_NAME}}_INDEX ON {{TABLE_NAME}} ({{INDEX_COLUMNS}})"
          mysql.recordDeleteQuery: "DELETE FROM {{TABLE_NAME}} {{CONDITION}}"
          mysql.recordExistsQuery: "SELECT 1 FROM {{TABLE_NAME}} {{CONDITION}} LIMIT 1"

@RukshiW I have done the changes @senthuran16 mentioned for all doc spaces except 400(Not enough access). Could we migrate the latest change for the specific doc version and close this issue?

[RukshiW]

Did the same changes in the SP 4.0.0 space.
