Introduction

tsfile-mt is a TsFile management tool. Currently, we support bit granularity parsing of TsFile and provide visual display.

1. ChunkGroup and Index display: This tool can Clearly display information of each part of TsFile, details are as follows:

   1. The versionNumber.

   2. The data layer: contains details of each level and statistic information.

      i. ChunkGroup

      ii. Chunk

      iii. Page

      iv. Point

   3. The index layer: displayed in a B+ tree like structure then you can easily view the overall structure of the secondary index(entity and measurement granularity).

2. Timeseries and measurement search: In addition to displaying data, we also provide the function of querying TimeSeries by keyword. There is a linkage between the index layer and the data layer, it can quickly locate the desired TimeSeries with details.

3. The encoding and compression type of a timeseries analysis: tsfile-mt provide the analysis of the current timeseries encoding and compression. In addition, tsfile-mt also provide the analysis of the combination of various encoding and compression types of the timeseries.

Quick Start

Prerequisites

To use Tool-offline-for-IoTDB, you need to have:

1. Java >= 1.8 (Note: Because we use JavaFx to develop front end and JavaFx is dependent in JDK11, if the version of the JDK you use > 1.8, you need to import the relevant libraries.)
2. Maven >= 3.6

Compile

You can download the source code from:

git clone https://github.com/lpf4254302/tsfile-mt.git

Under the root path of tsfile-mt:

mvn clean install

Under the root path of tsfile-mt-ui project, use the following command to assemble the project into a executable jar:

mvn assembly:assembly -D skipTests

The you can use the following command to start the project directly:

java -cp .\tsfile-mt-ui-0.2.0-SNAPSHOT-jar-with-dependencies.jar org.apache.iotdb.tool.ui.IUIApplication
