Trait CdcSourceRuntimeFlags

Behavior switches.

Provided Associated Constants

const CAN_BACKFILL: bool = false

When true, only shared sources are supported; otherwise only direct sources are supported.

const CAN_BACKFILL_IN_PARALLEL: bool = false

When true, the planner may choose parallelized backfill.

const CAN_USE_TRANSACTION_METADATA: bool = false

When true, a shared source sets Debezium’s provide.transaction.metadata, so that all rows of one upstream transaction go into a single chunk.

const NEEDS_NON_EMPTY_INITIAL_OFFSET: bool = false

When true, the source executor waits for a non-empty split offset before reporting the initial CDC offset.

const NEEDS_OFFSET_COMMIT_ON_CHECKPOINT: bool = false

When true, the consumed offset is committed back to the upstream database on each checkpoint via a JNI call.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
