Test suite for Orma (v0.6.0)

[gfx]

Orma を追加しました。

OrmaTest.java が妥当かどうかご確認ください。

なお手元のNexus 9 (Marshmallow) で2回実行すると↓のようになりました。

adb logcat -t 1000 | ag OrmaTest: | perl -p -E 's/^.*OrmaTest: //'

Insert on ORMA (BulkMode:ON): begin
Insert on ORMA (BulkMode:ON):      270 ms, Insert 10000 records.
Insert on ORMA (BulkMode:ON):      48 ms, Select Records.
Insert on ORMA (BulkMode:ON): end, 318 ms
Insert on ORMA (BulkMode:OFF): begin
Insert on ORMA (BulkMode:OFF):      8440 ms, Insert 10000 records.
Insert on ORMA (BulkMode:OFF):      42 ms, Select Records.
Insert on ORMA (BulkMode:OFF): end, 8482 ms
Insert on ORMA (BulkMode:ON): begin
Insert on ORMA (BulkMode:ON):      255 ms, Insert 10000 records.
Insert on ORMA (BulkMode:ON):      42 ms, Select Records.
Insert on ORMA (BulkMode:ON): end, 297 ms
Insert on ORMA (BulkMode:OFF): begin
Insert on ORMA (BulkMode:OFF):      11062 ms, Insert 10000 records.
Insert on ORMA (BulkMode:OFF):      40 ms, Select Records.
Insert on ORMA (BulkMode:OFF): end, 11102 ms

同じ端末でのRealm (v0.84.2)の結果は↓です。

adb logcat -t 1000 | ag RealmTest: | perl -p -E 's/^.*RealmTest: //'

Insert on REALM (BulkMode:ON): begin
Insert on REALM (BulkMode:ON):      346 ms, Insert 10000 records.
Insert on REALM (BulkMode:ON):      4 ms, Select Records.
Insert on REALM (BulkMode:ON):      38 ms, Manual Import!: Select Records.
Insert on REALM (BulkMode:ON): end, 388 ms
Insert on REALM (BulkMode:OFF): begin
Insert on REALM (BulkMode:OFF):      56026 ms, Insert 10000 records.
Insert on REALM (BulkMode:OFF):      3 ms, Select Records.
Insert on REALM (BulkMode:OFF):      30 ms, Manual Import!: Select Records.
Insert on REALM (BulkMode:OFF): end, 56059 ms
Insert on REALM (BulkMode:ON): begin
Insert on REALM (BulkMode:ON):      318 ms, Insert 10000 records.
Insert on REALM (BulkMode:ON):      2 ms, Select Records.
Insert on REALM (BulkMode:ON):      31 ms, Manual Import!: Select Records.
Insert on REALM (BulkMode:ON): end, 351 ms
Insert on REALM (BulkMode:OFF): begin
Insert on REALM (BulkMode:OFF):      57327 ms, Insert 10000 records.
Insert on REALM (BulkMode:OFF):      1 ms, Select Records.
Insert on REALM (BulkMode:OFF):      27 ms, Manual Import!: Select Records.
Insert on REALM (BulkMode:OFF): end, 57355 ms

ところで、Realmは findAll() -> RealmResults<T> を行った時点ではクエリを発行しないようです。RealmResultsから値を取り出そうとして初めてクエリを発行するようですね。なので、manual importまでしてはじめて等価のオペレーションといってよさそうです。

Realmが爆速といわれるのは案外ベンチマークコードの間違いで、現状（v0.8x）だと最適化されたSQLiteベースのORMと実は大差ないという可能性がありますね。

ありがとうございます！

「ところで」の件ですが、昨年にデータ計測をしたときにも少し気づいていたのですが、
集計に反映させることができていなかったので今年はそのあたりも確認したいです
