Hi, I summary the in-progress or todo works that I focus on:
On jira: - The merge module for sequence data file and unsequence data file (seems has finished yesterday..), and its related tools. - New Antlr parser for better performance of parsing SQL - PreparedStatement implementation for avoid parsing SQL repeatedly - More time series metadata statistics API - Path ID: Try using Long format to describe a time series rather than a string. - attach a watermark on the query result for data provenience - External sort data if there are too much data - Cache: add API for knowing the hit ratio statistics (and then improve cache) - distributed version (cluster mode): try to merge the branch 'cluster' into master, and support scalability. - sync module: sync data files from one IoTDB instance to another. - Spark: change the table schema in spark as <time, device/data_source, measurement1, measurement2 ...> not on JIRA but I'd like to do: - New RPC interface to avoid to use SQL for better performance - Accelerate the query: if a page header does not satisfy the filter, return immediately (if possible) - Hadoop module: support MR on Tsfile Ok... after listing them together, I realize that we have so many works to do...
