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"
}
from kafka-connect-bigquery.
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.
