Udviklere af den distribuerede CockroachDB database at de kun havde to blokke tilbage \/8.<\/a><\/noindex> om overs\u00e6ttelse af projektets kildekoder til en kombination af licenser<\/a><\/noindex> Business Source License (BSL) og Cockroach Community License (CCL), som ikke er fri p\u00e5 grund af diskrimination mod bestemte brugergrupper. BSL-licensen blev for tre \u00e5r siden er foresl\u00e5et<\/a><\/noindex> grundlagt af MySQL-stifterne som et alternativ til Open Core-modellen. Hovedpunktet med BSL er, at koden til udvidet funktionalitet oprindeligt er tilg\u00e6ngelig for \u00e6ndringer, men i en vis periode kun kan anvendes gratis under overholdelse af yderligere betingelser, for at omg\u00e5 hvilke der kr\u00e6ves k\u00f8b af en kommerciel licens.<\/p>\n

Den nye licens tillader brug af CockroachDB p\u00e5 et vilk\u00e5rligt antal noder i klyngen og indlejring i applikationer, herunder dem der s\u00e6lges til kunder eller udf\u00f8res som tjenester. Den eneste begr\u00e6nsning, der forhindrer, at licensen betragtes som fri og \u00e5ben, er forbuddet mod salg af kommercielle versioner af CockroachDB udf\u00f8rt i form af cloud-tjenester. For at tilbyde CockroachDB som betalings-cloud-tjenester kr\u00e6ves der nu k\u00f8b af en kommerciel licens.<\/p>\n

Den tidligere offentliggjorte kode forbliver<\/a><\/noindex> under Apache 2.0 licensen og er tilg\u00e6ngelig for at danne forks. Desuden vil koden efter tre \u00e5r fra udgivelsestidspunktet blive frigivet fra BSL og distribueres under den almindelige Apache 2.0 licens. For eksempel forventes udgivelsen af
\n CockroachDB 19.2 inden oktober 2022 at blive leveret under BSL, hvorefter den automatisk vil blive licenseret under Apache 2.0 licensen. If\u00f8lge udviklerne vil en s\u00e5dan tidsm\u00e6ssig forskydning muligg\u00f8re udvikling af et konkurrerende produkt til DBaaS (database som en tjeneste) applikationer, samtidig med at det sikrer \u00e5benhed af de grundl\u00e6ggende kildekoder og undg\u00e5r at g\u00e5 over til Open Core-modellen.<\/p>\n

Som i tilf\u00e6lde af genlicensering af MongoDB<\/a><\/noindex>, Redis-moduler<\/a><\/noindex> og TimescaleDB<\/a><\/noindex> \u00c5rsagen til overgangen til en ikke-frigivet licens er kampen mod udnyttelse fra udbydere af cloud-tjenester, der skaber afledte kommercielle produkter og gen-s\u00e6lger \u00e5bne databasesystemer som cloud-tjenester, men ikke deltager i f\u00e6llesskabet og ikke hj\u00e6lper med udviklingen. Det skaber en situation, hvor profitten g\u00e5r til ubestridte cloud-udbydere, der gen-s\u00e6lger f\u00e6rdige \u00e5bne l\u00f8sninger, mens de direkte udviklere st\u00e5r tilbage med ingenting. <\/p>\n

Lad os minde om, at databasesystemet CockroachDB objektorienteret<\/a><\/noindex> er designet til at skabe h\u00f8jt p\u00e5lidelige geografisk distribuerede og horisontalt skalerbare lagre, der udm\u00e6rker sig ved h\u00f8j livskraft og ikke er afh\u00e6ngige af fejl p\u00e5 drev, noder og datacentre. CockroachDB garanterer ACID-transaktionsintegritet, giver mulighed for brug af SQL til datamanipulation, tillader \u00e6ndringer i lagerskemaet p\u00e5 farten, underst\u00f8tter indeks og fremmede n\u00f8gler, samt automatisk replikation og genbalance af lageret.<\/p>\n
