We might want to support TsFile in different languages: Go, Rust, C and C++ as parquet/arrow people are doing.

Use of generics.

Hello again, i am in learning mode. I've seen in the Tablet.java an array of Object[] and i want to know the rational of this. We know that in Java generics are "fake" due to the type erasure, but is there any possibility to replace that: *** deviceId of this tablet */

Hi Julian, Let TsFile supporting SQL is attractive. However, as it may have some limitations, e.g., a tsfile does not support out-of-order data integration for a given time series. It will limit the usage scenarios: if a embedded machine can run TsFile with Java, why not run IoTDB The

Big +1 for fixed Endianness! I think a C implementation would also be beneficial for something like a sqlite interface (see my thread here https://lists.apache.org/thread.html/rd4d0296e0fef9c1c822f605f641d829047e0932429499a5e05667b8e%40%3Cdev.iotdb.apache.org%3E) as it could be wrapped to

2021-09-28 Thread Julian Feinauer
Hi folks, I just came up with a little idea to improve the usage of TSFiles at the „edge“. What if we create an access layer (besides the Readers /Writers) to access the TSFiles with SQL as if they were in the server. Thats basically the same that sqlite does with extreme success
