You could specify except_table, that tables will not sync。
BTW, except_table could be "table1, table2,table3", separate by comma

Please add a regression test for the except tables, and cover the below situations on the except tables:

1. normal insert
2. add/drop partition
3. drop table
4. alter/truncate table
5. light schema change on the table

[w41ter]

Define it to an array might be better.

Suggested change

	ExceptTable string `json:"except_table"`
	ExceptTables []string `json:"except_tables"`

[w41ter]

Then run strings.TrimSpace(exceptTable) before converting jobContext to Job.

[w41ter]

Suggested change

	exceptTable string
	exceptTables []string

[w41ter]

Suggested change

	ExceptTable string `json:"except_table"`
	ExceptTables []string `json:"except_tables"`

[w41ter]

Define it as a method of Job.

It likes:

func (j *Job) isExceptTable(targetTable string) bool {

[w41ter]

There may be thousands of tables here, so it is not suitable for printing logs.

[w41ter]

GetTableNameById is a high-cost operation, it needs to connect doris FE and execute 'SHOW TABLE'.

One possible solution is to query the table ID of the except tables before adding the job to JobManager, see Job::FirstRun for details.
