[Xapian-discuss] Concurrency during update/merge

[George Wu]

Dear all,

I am new to Xapian and actually I am evulating how Xapian is suitable
for our project.

One of our concern is concurrency during update/index flush operation.
Can a Xapian instance handle read during update/index flush operation?

Also, real-time search is important in our application.  In a previous
post I learnt that there can only be one Xapian instance having a write
access.  For other read-only instance, the database have to be reopened
before the newly inserted data is visible to read-only instances.  In
this case, how fast and how efficient is the index-reopen operation?

Thanks a lot!
