    A schema
    A collection of tables
    Which is also a table
    You can have views fined as queries
    And a DB which has many schemas
    Under the hood they are a collection of pools, pools and journals

    Ok, got it. This is down the line when there is "query service" either local or network. Browsing database content is definitely essential

    I think it might be an idea to have benchmark suite against competition as part of your CI
    Vlad Ilyushchenko
    @bluestreak01
    I am going to need help with that to have impartial benchmark. The only thing I need from CI is that my changes do not make existing paths slower relative to previous build

    Another project I stumbled upon. Not fast but interesting: https://geteventstore.com/

    I had a look at that parser before writing my flat file import. Not bad, but too complex and slow for what I needed. Nfsdb parser twice as fast as univocity in the very same file.

    Might be of some interest to your work: https://calcite.incubator.apache.org/
    Actually you can have Calccite as a frondend

    @sirinath
    What are your thoughts on Apache Calcite?
    This looks cool to have as the front end
    May be it can be one front end

    This is a very useful idea, in fact my friend is doing very similar project for a bank. It is very useful to integrate legacy data sources under single query system. That said what i'm doing is slightly different. Calcite query system simply would not do for my project for three reasons: its query system does not offer functionality beyond what you get from individual databases, it looks more of an overlap between functionality of data sources it supports (check what kind of query functionality splunk provides vs. calcite). Pick a source file on calcite github and search for "new " operator usage, it is far too many for what i'm building. Third: name sounds strange (https://en.wikipedia.org/wiki/Calcite) what does it have to do with either querying or integration? ;)
    may be one day somebody would honour my project by writing an adaptor for calcite? :smile:

    Came back from holiday today :) I found that I need rewritable in-memory structure for some functions, as-of join being one. I'm writing and testing that. It'll prompt some exciting query capabilities once done.

    Not heard of this project before, but it is very interesting, I think this could be of use!

    Great to see some commits.
    Some project I stumbled upon: http://impala.io/, http://getkudu.io/

    Just wanted to say this project looks interesting. Will see if a potential use case comes up to use it.

    Thanks, we are evolving to maximise use cases :)
