My naïve assumption that specifying lifecycle policy for _spark_metadata with
longer retention will solve the issue

If you are on aws, you can use RDS + AWS DMS to save data to s3 and then read
streaming data with spark structured streaming from s3 into hive

Hi Sean
Persisting/caching is useful when you’re going to reuse dataframe. So in your
case no persisting/caching is required. This is regarding to “when”.
The “where” usually belongs to the closest point of reusing
calculations/transformations
Btw, I’m not sure if caching is useful when you

Not a big expert on Spark, but I’m not really understand how you are going to
compare and what? Reading-writing to and from Hdfs? How does it related to yarn
and k8s… these are recourse managers (YARN yet another resource manager) : what
and how much to allocate and when… (cpu, ram).

You can do the enrichment with stream(events)-static(device table) join when
the device table is slow changing dimension (let’s say once a day change) and
it’s in delta format, then for every micro batch with stream-static John the
device table will be rescanned and up to date device data will
Assuming that all tables have same schema, you can make entire global
table partitioned by some column. Then apply specific UGOs permissions/ACLs per
partition subdirectory

Hi, Mohammed
I think that the reason that only one executor is running and have single
partition is because you have single file that might be read/loaded into memory.
In order to achieve better parallelism I’d suggest to split the csv file.
Another problem is question: why are you using rdd?
Spark-submit --conf spark.hadoop.fs.permissions.umask-mode=007
You may also set sticky bit on staging dir

I think MaxOffsetsPerTrigger in Spark + Kafka integration docs would meet your
requirement

It seems that thread converted to holy war that has nothing to do with original
