Hi,
I'm using runtime 15.4 LTS or 14.3 LTS. When loading a delta lake table from Kinesis, I found the delta log checkpoint is in mixing formats like:

7616 00000000000003291896.checkpoint.b1c24725-....json
7616 00000000000003291906.checkpoint.873e1b3e-....json
7616 00000000000003291916.checkpoint.e14e7613-....json
7616 00000000000003291926.checkpoint.3c9a0512-....json
7616 00000000000003291936.checkpoint.ba87e77a-....json
7653 00000000000003291936.checkpoint.parquet
7616 00000000000003291946.checkpoint.daf933a4-....json
7616 00000000000003291956.checkpoint.80768fb1-....json
7614 00000000000003291961.checkpoint.59ad2faf-....json
7614 00000000000003291971.checkpoint.ddb7a4f4-....json
7614 00000000000003291981.checkpoint.45867b1a-....json
7614 00000000000003291991.checkpoint.ec13fc70-....json

why it has mixed classic and v2 checkpoints together?

Thanks
