8 | # This testfile is in sections because the goal is to verify the behavior |
9 | # when a reindex occurs during an active transaction, both as a result of the |
10 | # transaction's actions as well as the result of the HEAD's actions. In order |
11 | # to keep this test quick, it's easier to restart and hit the known |
12 | # reindexing at 17 keys vs. attempting to hit the second-level reindex which |
13 | # can occur as early as 18 keys and as late as 4097 (256*16+1) keys. |
