# Test a file L1.000203 that would be a candidate for a move compaction into
|
|
# L2, except that it's bordered by two files participating in the same
|
|
# compaction. This is possible if 000203 created by a L0->L1 compaction that
|
|
# completed after the compaction of 000201 and 000202 began.
|
|
#
|
|
# The in-progress compaction of 000201 and 000202 will write an output table
|
|
# to L2 that would conflict with 000203 if 000203 was moved into L2.
|
|
#
|
|
# NB: The L0 files are used to increase the permitted compaction concurrency.
