Hi All,

My first post in this group. I'd like to ask something that's not
technical but about the H2 project in general.

First I should tell about why I am posting here. I am currently using
H2 in a prototype of an application that does what is often called
"fuzzy matching". Conceptually fuzzy matching can be seen as that one
makes a Cartesian product of two relations and computes for every
record pair similarity scores using some metric(s) (like edit-
distance, soundex, cosine similarity, ...). The similarity scores are
used to determine in a (semi) automated fashion whether or not a
record pair matches (represents the same real-world entity). Fuzzy
matching can for example occur as part of a data integration task.
Technically it means for my application that that are a lot of
sequential scans/inserts/sortings/aggregations on large data sets,
sometimes with low latency requirements as to provide an interactive
user interface. The main reasons for me to go for H2 is performance in
combination with platform independence.

On topic:
I have noticed that one can make binary taxonomy of open source
projects as follows: the first type is where the project seems to be a
team effort; the second type that seem to be heavily centered around
one individual. I also noticed while looking at the H2 repository that
practically all commits are done by Thomas Mueller. This fact made me
wonder how much this project is depending on one person. I'd like to
hear the opinions of this group.

I searched the H2 website for something about how the project is
organized; I couldn't find more than a piece on the history of H2. I'd
like to know how the H2 project is organized. How many people are
involved? and in what way?

Kind regards,

Vasco
