Davies Liu commented on SPARK-9588: ----------------------------------- cc [~lian cheng], Does the partition improvement in 1.5 work in this case? > spark sql cache: partition level cache eviction > ----------------------------------------------- > > Key: SPARK-9588 > URL: https://issues.apache.org/jira/browse/SPARK-9588 > Project: Spark > Issue Type: Improvement > Reporter: Shenghu Yang > > In spark 1.4, we can only do 'cache table <table_name>'. However, if we have > table which will get a new partition periodically, say every 10 minutes, we > have to do 'uncache' & then 'cache' the whole table, taking long time. > Things would be much faster if we can do: > (1) cache table <table_name> partition <newest_partition> > (2) uncache table <table_name> partition <oldest_partition> > This way we will alway have a sliding window type of cached data. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
