To be specific, some of the frames are the same but some of them are different. I am not sure which step did I make that mistake +#### Video Data Structure +* There are no real difference between how data are stored for video and image, except there is an extra column in both database for order so that I can recreate our origional dataset. +## Conclusion: +this has been a busy and stressful but fulfilling project, I learned to work with databases in a dockerized envionment along with setting up docker container and compose file. This will be veru valueable for my future considering how useful docker is. \ No newline at end of file diff --git a/sorrentum_sandbox/spring2024/Spring2024_Simple_Data_Migration_from_RethinkDB_to_MariaDB/Rethinkdb/dockerfile b/sorrentum_sandbox/spring2024/Spring2024_Simple_Data_Migration_from_RethinkDB_to_MariaDB/Rethinkdb/dockerfile new file mode 100644 index 0000000000..37070b7bd4 --- /dev/null +++ b/sorrentum_sandbox/spring2024/Spring2024_Simple_Data_Migration_from_RethinkDB_to_MariaDB/Rethinkdb/dockerfile @@ -0,0 +1,16 @@ +#import rethinkdb docker image +FROM rethinkdb:2.4.3 +#setup work directory +WORKDIR /app + +# Define default command. +CMD ["rethinkdb", "--bind", "all"] + +# Expose ports. +# -
