Highlights

Named databases checkpoint and open in bounded memory. A named .loradb database's sync() used to build the whole snapshot in memory, several copies deep, and the archive kept it resident afterwards; opening decoded it the same way. Both now stream. On a 3M-node graph (630 MiB in memory):

v0.27.1 v0.28.0
sync(), peak heap over the graph +5.4 GiB +11 MiB
open, peak heap over the graph +5.3 GiB +13 MiB
process max RSS (macOS) 6.45 GB 1.13 GB
RSS under glibc over three sync() calls (1M nodes) 1.2 → 1.9 GB flat at 305 MiB
.loradb size 155 MB 54 MB
open 14.3 s 8.9 s
sync() 9.4 s 4.6 s

Writers no longer wait while sync() writes the snapshot, only while it takes the graph and its WAL position. recover, managed checkpoints, checkpoint_to and save_snapshot_to use the same streaming path. The snapshot format is unchanged: v0.27 archives open in v0.28, and v0.28 archives open in v0.27.

Breaking change

sync() on a named database now drops the WAL its snapshot covers. Until now the archive kept every WAL segment since the database was created. A change feed on a named database can therefore resume only from the last sync() onwards; an older fromLsn fails with LORA_CHANGES_TRUNCATED, the same as after a managed checkpoint. Resuming after the last sync() replays over the archive's snapshot as before.

Testing

Besides the test suites, 1,200 kill -9 rounds on macOS and Linux killed a writer at random points (in writes, in sync() and in open), and every acknowledged write survived with the graph intact.
