Hi all,
I'm developing data processing service and evaluating if Pytable. Since hdf5
supports hierarchical data like a tree of folder, can I use such a tree-like
structure as a K-V store like possibly store million of tables or arrays under
one group and randomly access any one of them in O(1) time? e.g.
root/
user_log/
uid1-> table / array, (of tens of thousand rows / elements,
ETL'ed user log info in int format)
uid2-> table / array,
uid3-> table / array,
uid4-> table / array,
uid5-> table / array,
…… (perhaps million user)
Just wondering how the hierarchical structure is implemented and such usage
pattern is supported? if no, is there any running or better way to store such
type of information? We adopt Pytables because the data is stored in higher
density, faster loaded and no ACID / concurrency overhead, so traditional DB
and no-sql db is not our option..
Thanks,
Jason
