(none) Long The maximum delay between two adjacent batches, which used to create MinRowsReadLimit with read.stream.minRowsPerTrigger together.
read.stream.minRowsPerTrigger
(none) Long The minimum number of rows returned in a single batch, which used to create MinRowsReadLimit with read.stream.maxTriggerDelayMs together.
requiredSparkConfsCheck.enabled
true Boolean Whether to verify SparkSession is initialized with required configurations.
write.merge-schema
