Cassandra Source Connector lacks documentation regarding BUCKETTIMESERIES incremental mode

[antomys]

There is an implemented BUCKETTIMESERIES incremental mode in the Cassandra source, but no documentation exists.

object TimestampType extends Enumeration {
  type TimestampType = Value
  val TIMESTAMP, DSESEARCHTIMESTAMP, TIMEUUID, TOKEN, BUCKETTIMESERIES, NONE = Value
}

What should be added to the documentation:

• Incremental mode: BUCKETTIMESERIES.

• Documentation for fields, which are used for BUCKETTIMESERIES mode:

  val BUCKET_TIME_SERIES_MODE     = s"$CONNECTOR_PREFIX.bucket.timeseries.mode"
  val BUCKET_TIME_SERIES_MODE_DOC = "The bucket mode to retrieve timeseries data. DAY, HOUR, MINUTE, SECOND."

  val BUCKET_TIME_SERIES_FORMAT     = s"$CONNECTOR_PREFIX.bucket.timeseries.format"
  val BUCKET_TIME_SERIES_FORMAT_DOC = "The bucket format to retrieve timeseries data"

  val BUCKET_TIME_SERIES_FIELD_NAME         = s"$CONNECTOR_PREFIX.bucket.timeseries.field.name"
  val BUCKET_TIME_SERIES_FIELD_NAME_DOC     = "The name of the field to use on bucket"
  val BUCKET_TIME_SERIES_FIELD_NAME_DEFAULT = "bucket"

• Also, there is no documentation regarding the following configuration fields:

  val CONNECT_TIMEOUT         = s"$CONNECTOR_PREFIX.connect.timeout.ms"
  val CONNECT_TIMEOUT_DOC     = "The Cassandra driver connection timeout in milliseconds."
  val DEFAULT_CONNECT_TIMEOUT = 5000

  val READ_TIMEOUT         = s"$CONNECTOR_PREFIX.read.timeout.ms"
  val READ_TIMEOUT_DOC     = "The Cassandra driver read timeout in milliseconds."
  val DEFAULT_READ_TIMEOUT = 12000
