We do have the same errors on our side:

  • We only have one task per connector and table
  • No other DML by anything outside the connector
{
  "code" : 400,
  "errors" : [ {
    "domain" : "global",
    "location" : "q",
    "locationType" : "parameter",
    "message" : "Could not serialize access to table xxx due to concurrent update",
    "reason" : "invalidQuery"
  } ],
  "message" : "Could not serialize access to table xxx due to concurrent update",
  "status" : "INVALID_ARGUMENT"
}

I made following changes to reduce the errors.

tasks.max: "1",
intermediateTableSuffix: mysuffix,
bufferSize: 100000
maxWriteSize: 10000
tableWriteSize: 1000

The above changes are in the connection configuration. I think the first three changes helped us reduce the errors to nearly 0.
