Crate tsfile_writer

This is a not yet feature complete Writer for TsFiles Version 3 (as defined from the Apache IoTDB Project). Currently not all features of TsFiles are supported. Most notably:

• No Aligned Chunks can be written
• Not all Encodings are available
• Not all DataTypes are supported
• Not all Compression Types are supported

But generally, the TsFiles written with this client are 100% compatible with TsFiles written in Java.

Quickstart

To write a TsFile just do something like

use tsfile_writer::writer::tsfile_writer::TsFileWriter;
use tsfile_writer::writer::IoTDBValue;
use tsfile_writer::writer::tsfile_writer::DataPoint;
use tsfile_writer::writer::schema::TsFileSchemaBuilder;
use tsfile_writer::writer::schema::DeviceBuilder;
use tsfile_writer::writer::TSDataType;
use tsfile_writer::writer::encoding::TSEncoding;
use tsfile_writer::writer::compression::CompressionType;

// Create the Schema
// Two devices with two sensors each
let schema = TsFileSchemaBuilder::new()
        .add(
            "d1",
            DeviceBuilder::new()
                .add(
                    "s1",
                    TSDataType::INT64,
                    TSEncoding::PLAIN,
                    CompressionType::UNCOMPRESSED,
                )
                .add(
                    "s2",
                    TSDataType::FLOAT,
                    TSEncoding::PLAIN,
                    CompressionType::UNCOMPRESSED,
                )
                .build(),
        )
        .add(
            "d2",
            DeviceBuilder::new()
                .add(
                    "s1",
                    TSDataType::INT64,
                    TSEncoding::PLAIN,
                    CompressionType::UNCOMPRESSED,
                )
                .add(
                    "s2",
                    TSDataType::FLOAT,
                    TSEncoding::PLAIN,
                    CompressionType::UNCOMPRESSED,
                )
                .build(),
        )
        .build();

// Create the writer
let mut writer = TsFileWriter::new(
    "target/benchmark2.tsfile",
    schema,
    Default::default(),
)
.unwrap();

// Write multiple timeseries at once
writer.write_many("d1",1, vec![
        DataPoint::new("s1", IoTDBValue::LONG(13)),
        DataPoint::new("s2", IoTDBValue::FLOAT(13.0 as f32)),
]);

// Write single series
writer.write("d2", "s1", 1, IoTDBValue::LONG(14));
writer.write("d2", "s2", 1, IoTDBValue::FLOAT(14.0 as f32));
