SQL Processors
This page describes the commands to manage SQL Processors in Lenses via the CLI.
The CLI can create, modify, pause, restart and remove Lenses SQL Processors.
View processors
View all processors registered. Optionally filter by name, cluster and namespace.
lenses-cli processors
# filter by namespace
lenses-cli processors --namespace lenses-sql
# Please note the following columns in the table:
# * 'ID' which should be used as the 'id' required for the commands below.
# * 'PROCESSORID' , which the user may have configured in creating the processor, and will be used as the consumer group of the processor.
Create processors
For IN_PROC you only need the name, for KUBERNETES all three. Creating an IN_PROC processor will start it automatically. This is not the case for Kubernetes deployments, a start command (see below) is required once created.
--id
(the processor id, optional)--name
(optional)--cluster-name
(should be passed ifKUBERNETES
)--namespace
(should be passed ifKUBERNETES
)--runners
(number of times to deploy while inKUBERNETES
)
lenses-cli processor create \
--name="processorName" \
--runners=1 \
--cluster-name="clusterName" \
--namespace="ns" \
--pipeline="prod" \
--sql="SET defaults.topic.autocreate=true;INSERT INTO topicB SELECT STREAM * FROM topic1"
From a file:
lenses-cli processor create ./processor.yaml
name: processorName
runners: 1
sql: |-
SET defaults.topic.autocreate=true;INSERT INTO topicB SELECT STREAM * FROM topic1
Stop a processor
For IN_PROC
you only need the name, for KUBERNETES
all three:
lenses-cli processor stop \
--cluster-name="clusterName?" \
--namespace="namespace?" \
--name="processorName"
Start a processor
For IN_PROC
you only need the name, for KUBERNETES
all three:
lenses-cli processor start \
--cluster-name="clusterName?" \
--namespace="namespace?" \
--name="processorName"
Update the number of runners
Update a processor from the command line flags or files. Only for KUBERNETES
:
lenses-cli processor update \
--cluster-name="clusterName?" \
--namespace="namespace" \
--name="processorName" \
--runners=2
From a file.
lenses-cli processor update ./processor.yaml
name: processorName
runners: 1
sql: |-
SET defaults.topic.autocreate=true;INSERT INTO topicB SELECT STREAM * FROM topic1
Delete a processor
Delete a processor by name, cluster and namespace. For IN_PROC
you only need the name, and for KUBERNETES
all 3 (name, cluster, namespace).
lenses-cli processor delete \
--namespace="namespace" \
--cluster-name="clusterName" \
--name="processorName
View processors logs
Available only for KUBERNETES
.
lenses-cli processors logs \
--cluster-name=clusterName \
--namespace=nameSpace \
--podName=runnerStateID [--follow --lines]
