连接器启动时的Debezium信号表

我对 Ad hoc snapshot signals 在debezium

假设我已经在数据库中创建了信号表 在创建CDC连接器之前 :

-- Creating the signal table
CREATE TABLE debezium_signal (id VARCHAR(42) PRIMARY KEY, type VARCHAR(32) NOT NULL, data VARCHAR(2048) NULL);

-- Starting a snapshot
INSERT INTO debezium_signal (id, type, data)
VALUES ('d139b9b7-7777-4547-917d-e1775ea61d41', 'execute-snapshot', '{"data-collections": ["servicedb.customers"]}')

现在,在创建并填充了这个表之后,我使用以下配置创建了我的CDC连接器:

{
    "name": "my_awesome_cdc_connector",
    "database.dbname": "servicedb",
    "table.include.list": "customers",
    "topic.prefix": "servicedb",
    "snapshot.mode": "schema_only",
    "snapshot.locking.mode": "none",
    "signal.enabled.channels": "source",
    "signal.data.collection": "servicedb.debezium_signal",
    "incremental.snapshot.allow.schema.changes": "true",
    "incremental.snapshot.chunk.size": 1024,
    "tombstones.on.delete": "true",
    "database.ssl.mode": "preferred",
    "poll.interval.ms": "1000",
    "max.batch.size": "1000",
    "output.data.format": "AVRO",
    "tasks.max": "1",
    "status": "RUNNING"
}

我的问题是:

由于我的debezium_signal表中已经有一个条目,当CDC连接器开始运行时,它会启动我的增量快照吗?

还是只考虑连接器创建后发送的信号?
