[cl-prevalence-devel] what concurrency approach you use with cl-prevalence

Hello everyone,

Could you share your approach to concurrency in combination with
cl-prevalence?

As far as I understand, simultaneous transactions (IOW modifications)
of the database are impossible, because all transactions use the same
transaction log file and therefore must happen sequentially to
avoid the transaction log corruption caused by concurrent writes.

What about reading operations for persistent data? Has anyone
implemented multiple-read/single write locking?

Or you don't care and just user one global lock for all your database?

Best regards,
- Anton
