Interface Summary

Interface	Description
CommitLogTransfer	Interface used to transfer commit logs
Event	An Event is a single unit that can be enqueued and processed by the QueueProcessor
FieldFilterSelector.FieldFilter
KafkaRecord	An interface that indicates the record can be converted to a Struct.
OffsetFlushPolicy	This policy determines how frequently the offset is flushed to disk.
OffsetWriter	Interface for recording offset.

Class Summary

Class	Description
AbstractDirectoryWatcher	Wrapper class around WatchService to make WatchService re-usable and avoid code repetition
AbstractProcessor	An abstract processor designed to be a convenient superclass for all concrete processors for Cassandra connector task.
BlackHoleCommitLogTransfer	Implementation of CommitLogTransfer which deletes commit logs.
CassandraClient	A wrapper around Cassandra driver that is used to query Cassandra table and table schema.
CassandraConnectorConfig	All configs used by a Cassandra connector agent.
CassandraConnectorContext	Contains contextual information and objects scoped to the lifecycle of CassandraConnectorTask implementation.
CassandraConnectorTask	A task that reads Cassandra commit log in CDC directory and generate corresponding data change events which will be emitted to Kafka.
CassandraConnectorTask.ProcessorGroup	A processor group consist of one or more processors; each processor will be running on a separate thread.
CassandraConnectorTaskHealthCheck
CassandraSourceInfoStructMaker
CassandraTopicSelector	Responsible for selecting the Kafka topic that the record will get send to.
CellData	Cell-level data about the source event.
ChangeRecord	An internal representation of a create/update/delete event.
CommitLogPostProcessor	The CommitLogPostProcessor is used to post-process commit logs in the COMMIT_LOG_RELOCATION_DIR once the commit log has been processed by the CommitLogProcessor.
CommitLogProcessor	The CommitLogProcessor is used to process CommitLog in CDC directory.
CommitLogProcessorMetrics
CommitLogReadHandlerImpl	Handler that implements CommitLogReadHandler interface provided by Cassandra source code.
CommitLogUtil	Utility class used by the CommitLogProcessor to compare/delete commit log files.
EOFEvent	An EOFEvent is an event that indicates a commit log has been processed (successfully or not).
FieldFilterSelector	This field filter selector is designed to determine the filter for excluding fields from a table.
FieldFilterSelector.Field	Representation of a fully qualified field, which has a KeyspaceTable and a field name.
FileOffsetWriter	A concrete implementation of OffsetWriter which tracks the progress of events being processed by the SnapshotProcessor and CommitLogProcessor to property files, snapshot_offset.properties and commitlog_offset.properties, respectively.
Filters	A utility class that contains various kinds of filters.
KafkaRecordEmitter	This emitter is responsible for emitting records to Kafka broker and managing offsets post send.
KeyspaceTable	The KeyspaceTable uniquely identifies each table in the Cassandra cluster
Module	Information about this module.
OffsetFlushPolicy.AlwaysFlushOffsetPolicy
OffsetFlushPolicy.PeriodicFlushOffsetPolicy
OffsetPosition	The OffsetPosition uniquely identifies a specific Mutation in a specific commit log.
QueueProcessor	A thread that constantly polls records from the queue and emit them to Kafka via the KafkaRecordEmitter.
Record	An immutable data structure representing a change event, and can be converted to a kafka connect Struct representing key/value of the change event.
RecordMaker	Responsible for generating ChangeRecord and/or TombstoneRecord for create/update/delete events, as well as EOF events.
RowData	Row-level data about the source event.
SchemaHolder	Caches the key and value schema for all CDC-enabled tables.
SchemaHolder.KeyValueSchema
SchemaProcessor	The schema processor is responsible for periodically refreshing the table schemas in Cassandra.
SnapshotProcessor	This reader is responsible for initial bootstrapping of a table, which entails converting each row into a change event and enqueueing that event to the ChangeEventQueue.
SnapshotProcessorMetrics
SourceInfo	Metadata about the source of the change event
TombstoneRecord	A TombstoneRecord is a record which has the same key as a delete event but has null value.

Enum Summary

Enum	Description
CassandraConnectorConfig.SnapshotMode	The set of predefined SnapshotMode options.
CellData.ColumnType	The type of a column in a Cassandra table
CommitLogReadHandlerImpl.PartitionType	A PartitionType represents the type of a PartitionUpdate.
CommitLogReadHandlerImpl.RowType	A RowType represents different types of Row-level modifications in a Cassandra table.
