### WAL file format - need to rename
WAL file will save multiple partial rows. One write TX's WAL may be split by
size => generates multiple {txn_id}_{segment_id}.wal
For the related data structs, such as ParitalRowBatch, refer to
https://github.com/decster/choco/blob/b644430e4e540da8ce0a6d13f07223c818706425/src/choco/partial_row_batch.h#L11
A WAL file has the same struct as PartialRowBatch, shown below. WAL file
size could be determined by config::write_buffer_size.
The schema part, we could reuse the definition in segment proto.
