MakeUpdater creates a Updater for the given table.

NewDatumRowConverter returns an instance of a DatumRowConverter.

NewDirectKVBatchFetcher creates a new KVBatchFetcher that uses the COL_BATCH_RESPONSE scan format for Scans (or ReverseScans, if reverse is true).

NewKVFetcher creates a new KVFetcher.

NewStreamingKVFetcher returns a new KVFetcher that utilizes the provided kvstreamer.Streamer to perform KV reads.

NewUniquenessConstraintViolationError creates an error that represents a violation of a UNIQUE constraint.

TestingSetDatumRowConverterBatchSize sets kvDatumRowConverterBatchSize and returns function to reset this setting back to its old value.

DebugRowFetch can be used to turn on some low-level debugging logs.

TableTruncateChunkSize is the maximum number of keys deleted per chunk during a table or index truncation.

TraceKVVerbosity is the verbosity level at which pretty printed KVs are logged.

UpdaterDefault indicates that an Updater should update everything about a row, including secondary indexes.

UpdaterOnlyColumns indicates that an Updater should only update the columns of a row and not the secondary indexes.

TestingInconsistentScanSleep introduces a sleep inside the fetcher after every KV batch (for inconsistent scans, currently used only for table statistics collection).

CellInfoAnnotation encapsulates the AST annotation for the various supported default expressions for import.

DatumRowConverter converts Datums into kvs and streams it to the destination channel.

KVFetcher wraps KVBatchFetcher, providing a NextKV interface that returns the next kv from its input.

KVProvider is a KVBatchFetcher that returns a set slice of kvs.

OriginTimetampCPutHelper is used by callers of Inserter, Updater, and Deleter when the caller wants updates to the primary key to be constructed using ConditionalPutRequests with the OriginTimestamp option set.

PartialIndexUpdateHelper keeps track of partial indexes that should be not be updated during a mutation.

RowHelper has the common methods for table row manipulations.

SeqChunkProvider uses the import job progress to read and write its sequence value chunks.
