d83eea7c60 Half size of each slot's bloom 2017-11-27 14:48:51 +00:00
Martin Sumner
c65dfa31d8 Add alternative bloom 
Bloom filter that can take largere keys but is still efficient to build.  Allows bloom filter to be checked without first detemrining the slot.  Also, as represents the whole SST - it could be sent to the penciller to remove the need for a message pass.

The bloom is smaller and has a worse fpr than leveled_tinybloom.  Failing the bloom check isn't so bad - due to the slot index check being relatively fast and having a very low fpr.

58946a7f98 Amend SST Timing Capture 
Use sampling mechansm from CDB timing capture.  Do it less though - as far more SST fetches in comparison to CDB fetches.

52c7a023a1 Stop using list 
Producing the list of all slots to try appeared to be expensive.  In volume tests taking 150 - 250 microseconds per GET.  Perhaps the list could be long (>1000), with a split and append, so not surprising.

Instead loop and count.

0208cde803 Drop sample size 
Scoring is relatively inaccurate - doesn't seem necessary to test sucha  bing sample, especially as eveyr file needs a score

c4456568be Expand testing 
Reasoned that the case clause (RHS of []) that was previously uncovered by tests - is so as it is not a possible outcome.

So case clause removed.

ee47d62c24 iclerk testing 
Not sure if this scenario is unlikely or impossible - but filtering it seems harmless.

Abstracting out function makes testing of scoring scenarios a bit easier.

Catch-up on setting specs for external functions in the iclerk.

22e894c928 Allow waste retnetion to be ignored 
If wast retention period is undefined, then it should be ignored - and no waste retained (rather than retaining waste for 24 hours as at present).

This wasn't working anyway - as reopen reader didn't get the cdb options (which didn't have the waste path on anyway) - so waste would not eb retained if the file had been opened after a stop/start.
