This has pros (like model-independence) and cons (storage overhead).<br/> Assuming schema-informedness, we should be able to provide a Set which is backed by an int (or a long, or a byte[]) plus a offset-to-name mapping. This would lower our storage requirements in places where we can assume such a mapping.</p> YANGTOOLS-1426

Consider bits type storage

Improvement Medium In Progress Unresolved Ruslan Kashapov Robert Varga Mon, 11 Apr 2022 19:13:40 +0000 Thu, 21 Dec 2023 08:54:25 +0000 14.0.0 data-impl data-util 0 3 <p>I have a few questions regarding this issue, compared to <a href="https://jira.opendaylight.org/browse/MDSAL-746" class="external-link" rel="nofollow">https://jira.opendaylight.org/browse/MDSAL-746</a>, I was working with bit values (0 or 1). <br/> In this case, storing these values was pretty straightforward, as these primitive types consist of booleans.<br/> However currently, I do not work with bit values, I work with bit names only. Hence, if will transform Set&lt;String&gt; to Integer, <br/> I still need to have this set of string names stored somewhere and mapped to the bit position.</p> <p>1. How is envisioned to replace Set&lt;String&gt; with Set backed by primitive data types such as int, long, and byte[]?<br/> 2. How would this lower storage requirement when this set of bit names still needs to exist?<br/> 3. What exactly is meant by offset-to-name mapping?</p> <p><a href="https://jira.opendaylight.org/secure/ViewProfile.jspa?name=rovarga" class="user-hover" rel="rovarga">rovarga</a> do you have any thoughts/advice? </p> <p>changes below are obsolete and can abandoned<br/> <a href="https://git.opendaylight.org/gerrit/c/yangtools/+/102901" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/c/yangtools/+/102901</a><br/> <a href="https://git.opendaylight.org/gerrit/c/yangtools/+/103058" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/c/yangtools/+/103058</a><br/> <a href="https://git.opendaylight.org/gerrit/c/mdsal/+/103029" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/c/mdsal/+/103029</a></p> <p>final change introducing dedicated Bits artifact<br/> <a href="https://git.opendaylight.org/gerrit/c/yangtools/+/103659" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/c/yangtools/+/103659</a><br/> addresses <a href="https://git.opendaylight.org/gerrit/c/yangtools/+/102901/comments/e0f469a5_4d2d8317" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/c/yangtools/+/102901/comments/e0f469a5_4d2d8317</a></p> <p> </p> Relates MDSAL-746 Development Rank 0|i0422n:
