<= 125 characters
pipeline - stringrequired
Name of the IndexPipeline used for processing output.
>= 1 characters
Match pattern: ^[a-zA-Z0-9_-]+$
diagnosticLogging - boolean
Enable diagnostic logging; disabled by default
Default: false
parserId - stringrequired
The Parser to use in the associated IndexPipeline.
coreProperties - Core Properties
Common behavior and performance settings.
fetchSettings - Fetch Settings
System level settings for controlling fetch behavior and performance.
indexingThreads - number
Maximum number of indexing threads; defaults to 4.This setting controls the number of threads in the indexing service used for processing content documents emitted by this datasource.Higher values can sometimes help with overall fetch performance.
>= 1
<= 10
exclusiveMinimum: false
exclusiveMaximum: false
Default: 4
Multiple of: 1
pluginInstances - number
Maximum number of plugin instances for distributed fetching. Only specified number of plugin instanceswill do fetching. This is useful for distributing load between different instances.
<= 500
exclusiveMinimum: false
exclusiveMaximum: false
Default: 0
Multiple of: 1
fetchResponseScheduledTimeout - number
The maximum amount of time for a response to be scheduled. The task will be canceled if this setting is exceeded.
>= 1000
<= 500000
exclusiveMinimum: false
exclusiveMaximum: false
Default: 300000
Multiple of: 1
numFetchThreads - number
Maximum number of fetch threads; defaults to 20.This setting controls the number of threads that call the Connectors fetch method.Higher values can, but not always, help with overall fetch performance.
>= 1
<= 500
exclusiveMinimum: false
exclusiveMaximum: false
Default: 20
Multiple of: 1
indexingInactivityTimeout - number
The maximum amount of time to wait for indexing results (in seconds). If exceeded, the job will fail with an indexing inactivity timeout.
>= 60
<= 691200
exclusiveMinimum: false
exclusiveMaximum: false
Default: 86400
Multiple of: 1
pluginInactivityTimeout - number
The maximum amount of time to wait for plugin activity (in seconds). If exceeded, the job will fail with a plugin inactivity timeout.
>= 60
<= 691200
exclusiveMinimum: false
exclusiveMaximum: false
Default: 600
Multiple of: 1
indexMetadata - boolean
When enabled the metadata of skipped items will be indexed to the content collection
Default: false
indexContentFields - boolean
When enabled, content fields will be indexed to the crawl-db collection
Default: false
id - stringrequired
A unique identifier for this Configuration.
>= 1 characters
Match pattern: ^[a-zA-Z0-9_-]+$
properties - JDBC properties
Plugin specific properties.
url - string
A URL to the database, e.g., 'jdbc:mysql://localhost/test'
driver - string
The class name of the JDBC driver to use to connect to the database.
query - string
A SQL SELECT statement to choose the records to be retrieved. For paginated queries, use the special variables ${limit} and ${offset}. The specific syntax will be driver dependent. Examples: Mysql - SELECT * FROM test_table LIMIT ${limit} OFFSET ${offset}, Microsoft SQLServer - SELECT * FROM test_table ORDER BY primary_key OFFSET ${offset} FETCH NEXT ${limit} ROWS ONLY
deltaQuery - string
An optional second query that will be used on re-crawls. It is intended to be used to save performance by returning only new/modified items. When used with Stray Content Deletion, any item not returned by this query will be deleted from the content collection after each re-crawl.
nestedQueries - array[string]
A nested query to join data from multiple tables. The nested query will be used with the SQL Statement and must include the primary key with the ${id} template. For example, 'SELECT column FROM table_fk WHERE pk_id=${id}'.
strayContentDeletionEnabled - boolean
When this feature is enabled, items not returned by the SQL query used for the crawl will be deleted from the content collection after each crawl. If it is disabled, no checks are performed for data freshness.
Default: true
primaryKey - string
The column name of the primary key for the table.
Default: id
username - string
The username of a database account used for authentication and data access.
password - string
The password of the account used for authentication and data access.
batchSize - number
Size of the batch during the statement execution

<= 2147483647
exclusiveMinimum: false
exclusiveMaximum: false
Default: 1000
Multiple of: 1
maxConnections - number
Maximum of connections in parallel to be used during statements execution
>= -2147483648
<= 2147483647
exclusiveMinimum: false

nestedQueryTimeOut - number
Timeout in minutes while executing a nested query statement

exclusiveMinimum: false
exclusiveMaximum: false
Default: 1

maximumItemLimitConfig - Item Count Limits
maxItems - number
Limits the number of items emitted to the configured IndexPipeline. The default is no limit (-1).
>= -2147483648
