• node
• storage, executor, reducer
• parser, segment
• ph, errors, fsutil

Roadmap

• UPSERT INTO query's path should be a string.
• TS() should be a function taking a string and returning a timestamp
• Basic query parsing on the client to determine if files need to be sent
• UPSERT INTO query in repl and server.
• node: Create server that can handle a raw query request
• REPL: readline to put full statements into history
• table namespacing within datasets?
• SHOW DATASETS
• SHOW TABLES FROM dataset
• DELETE FROM
• repl: Use Response interface for printing responses (see resp.go).
• Parser - generic comparison funcs parsing to type-specific funcs:
• SELECT RANGE
• SELECT RESAMPLE
• SELECT RESAMPLE window not half-open?
• SELECT RANGE should return time.Time values (UTC).
• SELECT RESAMPLE should return time.Time values where appropriate.
• SELECT RESAMPLE should only return the requested aggregates after reduction.

Later

• Agg functions: split MIN_MAX into MIN, MAX

• Agg functions: Rename NORMAL to SD (only return standard deviation)

• Use gzip on the wire? Optional?

• UPSERT INTO should return inserted row count (Storage.SegmentWrite)

• Add TIMESTAMP functions:

  • TS(string) -> TS
  • TS_FROM_UNIX(float64) -> TS
  • TS_SUB(TS, TS) -> float64

• UNDROP with existing table/dataset returns unexpected - can do better

• Add LIMIT clause to resample to limit the number of groups returned

• executor distinct query

• datatable tests for error conditions

• executor - how to test queries?

• datatable - Add checksum file w/ checksum for each data file
