VERSION_NUMBER_2

public static final int VERSION_NUMBER_2

In version 2, there is a bug with EnhancedString meta-data; requiring Java serialization to read it in. Additionally, the Enum constants include the promised encoding type.

See Also:

• Constant Field Values

VERSION_NUMBER_3

public static final int VERSION_NUMBER_3

Version 3 follows the document correctly; writing UTF-8 strings for the Encoding type of EnhancedStrings. Additionally, the Enum constants include an encoding type.

See Also:

• Constant Field Values

CURRENT_VERSION_NUMBER

FLAG_RECORD

public static final byte FLAG_RECORD

MAX_ENTRY_SIZE

public static final int MAX_ENTRY_SIZE

Max size for Row or Record entries. If we ever need a different max size for rows and records, introduce a new constant. Note: this is sourced from LogtailerConstants now. TODO: Max entry size does not include 4 byte checksum at the end of each V2 entry, at least in the BinaryRowV2 implementation. This should probably be corrected in a new release.

RECORD_TYPE_COMMAND

public static final int RECORD_TYPE_COMMAND

• Constant Field Values
