tsfile | columnar file format designed for time-series data | Time Series Database library

I configured TsFile synchronization. Schema already synchronizes, while the data is not synchronized. Have no idea why it would happen.enter image description here

I'm currently inserting data into IoTDB and I see some small TsFiles is merging into the large files. I would like to know how often the TsFiles be merged and how the merge process is triggered. Thanks!

How to convert TsFile into CSV when paths are unknown in IoTDB? The CSV should contain path, time, type, value, etc.

When a plan can not fit into the wal buffer, IoTDB throw an exception. However, I do not know how to set the wal_buffer_size.

I've tried to locale the TSFiles to HDFS, the config as below:

We are using Apache IoTDB Server in Version 0.11.2 in a scenario and observe a data directory / tsfiles that are way bigger than they should be (about 130 sensors with 4 Million double values for each sensor but the files are about 200gb).

Are there known issues or do you have any ideas what could cause this is how to track that down?

The only thing we could think off could be some merge artefacts as we do write many datapoints out of order so merging has to happen frequently.

Are there any ideas or tools on how to debug / inspect the tsfiles to get an idea whats happening here?

Any help or hints is appreciated!

I have a scenario where I have select dropdownlist(classification array). if my selecList has multiple values then ill display as a dropdown. if it has only one element in the array then by default it should be shown in selectList dropdown with that element selected by default. I need to write a condition where if classification element length is less orequal to 1 then show the element selected by default in matselect or display the list. Could you guys advise
