| Property | Type | Default | Importance | Description |
|---|---|---|---|---|
cdc.lob.mode | string | skip | medium | skip leaves CLOB, NCLOB, BLOB and XMLTYPE columns out of the records; inline assembles values from redo and publishes cdc.unavailable.placeholder where a value is not in the redo; reselect does the same and then queries the values that are still unavailable AS OF the commit SCN, one query per row. |
cdc.lob.max.bytes | long | 1048576 | medium | Largest LOB value published, in bytes (UTF-8 for CLOB and NCLOB). Larger values follow cdc.lob.oversize.action; assembly memory per value is bounded by this limit. |
cdc.lob.oversize.action | string | fail | medium | fail stops the task with CDC-3003 when a committed transaction wrote a LOB value above cdc.lob.max.bytes; placeholder publishes cdc.unavailable.placeholder instead. |
cdc.unavailable.placeholder | string | __cdc_unavailable_value | low | Value published for a LOB column whose value is not available (a before image, an unchanged LOB in an update, a partial write or an oversize value); BLOB columns carry its UTF-8 bytes. |
