Hi, I have few questions on modeling a time series use case with parquet and drill. I have seen the topic discussed at https://issues.apache.org/jira/browse/DRILL-3534.
My requirements are: * Keep the parquet files partitioned by year and month * For the current month, the data needs to be further partitioned by Week and Day * End of the running week, 7 daily parquets will be merged to a single weekly file * Similarly, weekly files will to be merged to form a monthly file during month end I will have a web application to generate the daily data and to ensure the batch runs/ atomic writes/locking etc. What are the possible ways to merge parquet files? Another CTAS? Is it possible to use parquet-tools(part of Parquet-MR) to merge multiple parquets(java jar ./parquet-tools-<VERSION>.jar <command> <input-directory> <output-file>) and then let drill query the results?. Will it impact the drill meta data caching mechanism?
