RAW: Send raw data from debezium.
INLINE: Send a row like in the source with only data (remove after & before), all the columns will be present for each row.
WRAP: Send a row like INLINE but wrapped in a record field.

`hostname`

Type: string
Dynamic: ✔️
Required: ✔️

Hostname of the remote server.

`ignoreDdl`

Type: boolean
Dynamic: ❌
Required: ✔️
Default: true

Ignore DDL statement.

Ignore CREATE, ALTER, DROP and TRUNCATE operations.

`key`

Type: string
Dynamic: ❌
Required: ✔️
Default: ADD_FIELD
Possible Values:
- ADD_FIELD
- DROP

Specify how to handle key.

Possible settings are:

ADD_FIELD: Add key(s) merged with columns.
DROP: Drop keys.

ADD_FIELD: Add metadata in a column named metadata.

`metadataFieldName`

Type: string
Dynamic: ❌
Required: ✔️
Default: metadata

The name of metadata field if metadata is ADD_FIELD.

`port`

Type: string
Dynamic: ✔️
Required: ✔️

Port of the remote server.

`serverId`

Type: string
Dynamic: ✔️
Required: ✔️

A numeric ID of this database client.

This must be unique across all currently-running database processes in the MySQL cluster. This connector joins the MySQL database cluster as another server (with this unique ID) so it can read the binlog. By default, a random number between 5400 and 6400 is generated, though the recommendation is to explicitly set a value.

`snapshotMode`

Type: string
Dynamic: ❌
Required: ✔️
Default: INITIAL
Possible Values:
- INITIAL
- INITIAL_ONLY
- WHEN_NEEDED
- NEVER
- SCHEMA_ONLY
- SCHEMA_ONLY_RECOVERY

Specifies the criteria for running a snapshot when the connector starts.

Possible settings are:

INITIAL: The connector runs a snapshot only when no offsets have been recorded for the logical server name.
INITIAL_ONLY: The connector runs a snapshot only when no offsets have been recorded for the logical server name and then stops; i.e. it will not read change events from the binlog.
WHEN_NEEDED: The connector runs a snapshot upon startup whenever it deems it necessary. That is, when no offsets are available, or when a previously recorded offset specifies a binlog location or GTID that is not available in the server.
NEVER: The connector never uses snapshots. Upon first startup with a logical server name, the connector reads from the beginning of the binlog. Configure this behavior with care. It is valid only when the binlog is guaranteed to contain the entire history of the database.
SCHEMA_ONLY: The connector runs a snapshot of the schemas and not the data. This setting is useful when you do not need the topics to contain a consistent snapshot of the data but need them to have only the changes since the connector was started.
SCHEMA_ONLY_RECOVERY: This is a recovery setting for a connector that has already been capturing changes. When you restart the connector, this setting enables recovery of a corrupted or lost database history topic. You might set it periodically to "clean up" a database history topic that has been growing unexpectedly. Database history topics require infinite retention.

`splitTable`

Type: string
Dynamic: ❌
Required: ✔️
Default: TABLE
Possible Values:
- OFF
- DATABASE
- TABLE

Split table on separate output uris.

Possible settings are:

TABLE: This will split all rows by tables on output with name database.table
DATABASE: This will split all rows by databases on output with name database.
OFF: This will NOT split all rows resulting in a single data output.

`stateName`

Type: string
Dynamic: ❌
Required: ✔️
Default: debezium-state

The name of the Debezium state file stored in the KV Store for that namespace.

`excludedColumns`

Type: object
Dynamic: ✔️
Required: ❌

An optional, comma-separated list of regular expressions that match the fully-qualified names of columns to include in change event record values.

Fully-qualified names for columns are of the form databaseName.tableName.columnName. Do not also specify the includedColumns connector configuration property."

`excludedDatabases`

Type: object
Dynamic: ✔️
Required: ❌

An optional, comma-separated list of regular expressions that match the names of databases for which you do not want to capture changes.

The connector captures changes in any database whose name is not in the excludedDatabases. Do not also set the includedDatabases connector configuration property.

`excludedTables`

Type: object
Dynamic: ✔️
Required: ❌

An optional, comma-separated list of regular expressions that match fully-qualified table identifiers for tables whose changes you do not want to capture.

The connector captures changes in any table not included in excludedTables. Each identifier is of the form databaseName.tableName. Do not also specify the includedTables connector configuration property.

`includedColumns`

Type: object
Dynamic: ✔️
Required: ❌

An optional, comma-separated list of regular expressions that match the fully-qualified names of columns to exclude from change event record values.

Fully-qualified names for columns are of the form databaseName.tableName.columnName. Do not also specify the excludedColumns connector configuration property.

`includedDatabases`

Type: object
Dynamic: ✔️
Required: ❌

An optional, comma-separated list of regular expressions that match the names of the databases for which to capture changes.

The connector does not capture changes in any database whose name is not in includedDatabases. By default, the connector captures changes in all databases. Do not also set the excludedDatabases connector configuration property.

`includedTables`

Type: object
Dynamic: ✔️
Required: ❌

An optional, comma-separated list of regular expressions that match fully-qualified table identifiers of tables whose changes you want to capture.

The connector does not capture changes in any table not included in includedTables. Each identifier is of the form databaseName.tableName. By default, the connector captures changes in every non-system table in each database whose changes are being captured. Do not also specify the excludedTables connector configuration property.

`maxDuration`

Type: string
Dynamic: ❌
Required: ❌
Format: duration

The maximum duration waiting for new rows.

It's not an hard limit and is evaluated every second. It is taken into account after the snapshot if any.

`maxRecords`

Type: integer
Dynamic: ❌
Required: ❌

The maximum number of rows to fetch before stopping.

It's not an hard limit and is evaluated every second.

`maxSnapshotDuration`

Type: string
Dynamic: ❌
Required: ❌
Default: 3600.000000000
Format: duration

The maximum duration waiting for the snapshot to ends.

It's not an hard limit and is evaluated every second. The properties 'maxRecord', 'maxDuration' and 'maxWait' are evaluated only after the snapshot is done.
