the implementation used queries based on "OR",
causing a perfromance problem as the query time
depends on the cardinality of the accounting.cdr
table.

CDR export jobs such as ama exporter or cdr-exporter must never execute
on both active/passive node. because the output folder resides on a
glusterfs filesystem, this will cause merged or duplicate files, and
calls charged twice to customers subsequentially.
for .ama, the 2-phase commit steps for exporting CDRs were separated
already:
(a) rename .tmp file to final output file name
(b) commit db transaction:
- cdrexportstatus of all cdrs of that file
- file sequence number increment
The implemented 2PC flow will prevent (a) properly, if (b) fails.
This is now leveraged (by escalating the UPSERT not changing anything) to
abandon a whole file, if a single CDR shows an exportstatus other than
"unexported". Such CDRs indicate there is a race condition with another
exporter (which was quicker here).
the same thechnique also has to be added to cdr-exporter, which
unfortunately has no 2PC flow impl yet.

if the number of exisiting subscribers (used as caller/callee
in created cdrs) is low, there is a higher risk that it can
fail to randomize one.

Let's try to make the experience a bit smoother, by tuning a bit the
dependency relationships for the obsolete transitional package.
We add versioned Breaks, and a version constraint to the existing
Replaces, against the obsolete package, so that we force an upgrade
in case we just install the libngcp-bulkprocessor-perl package.
We add a strict versioned dependency from the obsolete package to
the new one, so that we force a matching version, in case people
try to install the package standalone.

This reduces the complexity of the algorithm, at the expense of more
code, which makes it faster:
Rate old new
old 57803/s -- -23%
new 74906/s 30% --
