My firm is looking for an out-of-the-box database system to store and query high-frequency tick data. What are the best options? It seems that kdb+ is the market leader in this field.
An alternative is the TeaFiles file format. It's simple and boasts a high performance but I believe you'll have to reinvent some wheels.
kdb+ seems to be the leader but their programming language is a pain really. Personally I use a HDF5. It is a No-SQL database. It integrates very nicely with python.
I have been very happy with it so far.
velocity analytics might be a choice.
