Method Detail

setReadOffset

public StartPartitionSessionSettings.Builder setReadOffset(Long readOffset)

Reads in this partition session will start from offset no less than readOffset. If readOffset is set, server will check if that readOffset is not less than the actual committed offset. If the check fails then server will send an error message (status != SUCCESS) and close the stream. If readOffset is not set or is null (which is default), no check will be made. InitRequest.max_lag and InitRequest.read_from could lead to skip of more messages. Server will return data starting from offset that is maximum of actual committed offset, read_offset (if set) and offsets calculated from InitRequest.max_lag and InitRequest.read_from.

Parameters:

readOffset - Offset to read from. Default: null

Returns:

Builder

setCommitOffset

public StartPartitionSessionSettings.Builder setCommitOffset(Long commitOffset)

Make server know that all messages with offsets less than commitOffset were fully processed by client. Server will commit this position if it is not already done.

Parameters:

commitOffset - Commit offset, following the offset of last processed (committed) message. Default: null

Returns:
