typedef int64 Vertica::DateADT |
The value in DateADT is the number of days
typedef int64 Vertica::Interval |
Represents delta time.
The value in Interval is number of microseconds, which is limited to +/- 2^63-1 microseconds = 106751991 days 4 hours 54.775807 seconds or +/-9223372036854775807 months = 768614336404564650 years 7 months
Interval can be directly added/subtracted from Timestamp/TimestampTz to have a meaningful result

The value in TimestampTz is the number of microseconds since 2000-01-01 00:00:00 GMT
typedef int64 Vertica::TimeTzADT |
Represents time within a day in a timezone
The value in TimeADT consists of 2 parts:
enum Vertica::InputState |
InputState
Applies only to input streams; namely, UDFilter and UDParser.
OK Currently at the start of or in the middle of a stream.
END_OF_FILE Reached the end of the input stream. No further data is available. Returning a StreamState of INPUT_NEEDED at this point is invalid, as there is no more input.
END_OF_CHUNK Reached the end of an input chunk. Applies only to a parser and only when fed by a Chunker, it means the current data block ends on a record boundary. In this state a parser should consume all data in the block before returning from process.
START_OF_PORTION Used when a load stack is apportioned. This mode indicates input does not start at the beginning of a source. Typical response of a parser is to find the first end-of-record and return PORTION_START. Subsequent calls to process will use InputState = OK, until the end of the portion/source is reached.
END_OF_PORTION Used when a load stack is apportioned. This mode indicates the underlying source has reached the end of its allotted portion. The typical response from a parser is to finish the last record it started but proceed no farther.
enum Vertica::StreamState |
StreamState
Indicates the state of a stream after process() has handled some input and some output data.
The different enum values have the following meanings:
INPUT_NEEDED Indicates that a stream is unable to continue without being given more input. It may not have consumed all of its available input yet. It does not need to have consumed every byte of input. Not valid for output-only streams, ie., UDSources.
OUTPUT_NEEDED Indicates that a stream is unable to write more output without being given a new or larger output buffer. Basically that it has "filled" the buffer as much as it is reasonably able to (which may be every byte full, some bytes full, even completely empty – in which case Vertica assumes that the UDL needs a larger buffer). Not valid for input-only streams, ie., UDParsers.
DONE The stream has completed; it will not be writing any more output nor consuming any more input.
REJECT Only valid for UDParsers. Indicates that the last row the Parser consumed is invalid and should be processed as a rejected row.
KEEP_GOING Not commonly used. The stream has neither filled all of its output buffer nor consumed all of its input buffer, but would like to yield to the server. Typically it has neither consumed data nor produced data. This state should be used instead of a "wait" loop; a stream that is waiting for some external operation to complete should periodically return KEEP_GOING rather than simply blocking forever.
CHUNK_ALIGNED Used by UDChunker only. The chunker has found as many rows as possible in current block, and would like to hand off to parser a data block that is aligned with record boundary (input offset points to the start of the row after last row found in current block).
See the UDSource, UDFilter, and UDParser classes for how these streams are used.
Bit mast for communicatnig the available UDx debug logging levels.
