Debezium Oracle Capture

Debezium Oracle Capture
Certified
Wait for a change data capture event on Oracle server and capture the event as an internal storage file

Streams change data capture (CDC) events from an Oracle database using Debezium and writes them to Kestra's internal storage.

yaml
type: io.kestra.plugin.debezium.oracle.Capture

DROP: Don't send deleted row.

deletedFieldName string

Defaultdeleted

The name of deleted field if deleted is ADD_FIELD

excludedColumns object

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 object

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 object

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.

format string

DefaultINLINE

Possible Values

RAWINLINEWRAP

The format of the output

Possible settings are:

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.

ignoreDdl booleanstring

Defaulttrue

Ignore DDL statement

Ignore CREATE, ALTER, DROP and TRUNCATE operations.

includedColumns object

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 object

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 object

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.

key string

DefaultADD_FIELD

Possible Values

ADD_FIELDDROP

Specify how to handle key

Possible settings are:

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

maxDuration string

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 integerstring

The maximum number of rows to fetch before stopping

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

maxSnapshotDuration string

DefaultPT1H

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.

maxWait string

DefaultPT10S

The maximum total processing duration

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

metadata string

DefaultADD_FIELD

Possible Values

ADD_FIELDDROP

Specify how to handle metadata

Possible settings are:

ADD_FIELD: Add metadata in a column named metadata.
DROP: Drop metadata.

metadataFieldName string

Defaultmetadata

The name of metadata field if metadata is ADD_FIELD

offsetsCommitMode string

DefaultON_STOP

Possible Values

ON_EACH_BATCHON_STOP

When to commit the offsets to the KV Store

Possible values are:

ON_EACH_BATCH: after each batch of records consumed by this task, the offsets will be stored in the KV Store. This avoids any duplicated records being consumed but can be costly if many events are produced.
ON_STOP: when this task completes, the offsets will be stored in the KV Store. This avoids any un-necessary writes to the KV Store.

password string

Password on the remote server

pluggableDatabase string

The name of the Oracle pluggable database that the connector captures changes from. Used in container database (CDB) installations only

For non-container database (non-CDB) installation, do not specify the pluggableDatabase property.

pluginDefaultsRef string

Reference (ref) of the pluginDefaults to apply to this task.

properties object

Additional configuration properties

Any additional configuration properties that is valid for the current driver.

snapshotMode string

DefaultINITIAL

Possible Values

ALWAYSINITIALINITIAL_ONLYWHEN_NEEDEDNO_DATARECOVERY

Specifies the criteria for running a snapshot when the connector starts

Possible settings are:

ALWAYS: The connector runs a snapshot on each connector start.
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.
NO_DATA: 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.
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 string

DefaultTABLE

Possible Values

OFFDATABASETABLE

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 string

Defaultdebezium-state

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

username string

Username on the remote server

Outputs

size integer

The number of fetched rows

stateOffsetKey string

The KV Store key under which the combined Debezium state (offset + schema history) is stored

Both stateOffsetKey and stateHistoryKey point to the same combined entry written atomically. The entry holds a map with keys offsets and history so both states are always consistent.
