RecordSerializerFactory	marshalledMode(boolean marshalledMode) If marshalledMode is on, created serializer will read MarshalledRecord with raw binary data instead of actual record.
RecordSerializerFactory	recordDeserializeFilter(IgniteBiPredicate<WALRecord.RecordType,WALPointer> readTypeFilter) Specifies deserialization filter.
RecordSerializerFactory	skipPositionCheck(boolean skipPositionCheck) If skipPositionCheck is true, created serializer won't check that actual position of record in file is equal to position in saved record's WALPointer.
RecordSerializerFactory	writePointer(boolean writePointer) TODO: This flag was added under IGNITE-6029, but still unused.

Method Detail

createSerializer

RecordSerializer createSerializer(int ver)
                           throws IgniteCheckedException

Factory method for creation RecordSerializer.

Parameters:

ver - Serializer version.

Returns:

record serializer.

Throws:

IgniteCheckedException

writePointer

RecordSerializerFactory writePointer(boolean writePointer)

TODO: This flag was added under IGNITE-6029, but still unused. Should be either handled or removed.

Parameters:

writePointer - Write pointer flag.

recordDeserializeFilter

RecordSerializerFactory recordDeserializeFilter(IgniteBiPredicate<WALRecord.RecordType,WALPointer> readTypeFilter)

Specifies deserialization filter. Created serializer will read bulk FilteredRecord instead of actual record if record type/pointer doesn't satisfy filter.

Parameters:

readTypeFilter - Read type filter.

marshalledMode

RecordSerializerFactory marshalledMode(boolean marshalledMode)

If marshalledMode is on, created serializer will read MarshalledRecord with raw binary data instead of actual record. Useful for copying binary data from WAL.

Parameters:

marshalledMode - Marshalled mode.

skipPositionCheck

RecordSerializerFactory skipPositionCheck(boolean skipPositionCheck)

If skipPositionCheck is true, created serializer won't check that actual position of record in file is equal to position in saved record's WALPointer. Must be true if we are reading from compacted WAL segment.

Parameters:

skipPositionCheck - Skip position check.
