in reply to Multiuser app with SQLite, Dancer2 and CLI

Hello kaldor and welcome to the monastery and to the wonderful world of perl!

for the little i know SQLite is not well suited to multiple contemporary access. or maybe you will just have read access? See DBD::SqLite issue while accessing DB from multiple processes where sqlite_use_immediate_transaction is also suggested.

Regarding the duplication of code: abstract all parts needed by both interfaces and put them into a testable module.

    I expect to have much more read accesses than write.

    I use AutoCommit => 0, so immediate transactions are used by default. But you made me go through SQLite's documentation (again) : since the DB cannot be read at all while locked for writing, I'll have to deal with SQLITE_BUSY.

    In the end, usability will depend mostly on the DB/schema design (fast or slow updates). I'll stick to SQLite for now since I don't have any real-case metrics.

    Thanks.

      That was me posting here, by mistake as anonymous.

      Again, thank you all for your answers.
