> Write performance for each 1K batch degrades significantly when there are
> *10K* views being written in random with default
> {{phoenix.client.maxMetaDataCacheSize}}. With all views created, upsert rate
> remains around 25 seconds per 1K batch i.e. ~2K rows/min upsert rate.
> When {{phoenix.client.maxMetaDataCacheSize}} is increased to 100MB+ then view
> does not need to get re-resolved and upsert rate gets back to normal ~60K
> rows/min.
> With *100K* views and {{phoenix.client.maxMetaDataCacheSize}} set to 1GB, I
> wasn't able create all 100K views as upsert time for each 1K batch keeps on
> steadily increasing.
> Following graph shows 1K batch upsert rate over time with variation of number
> of views. Rows are upserted to random views {{CREATE VIEW IF NOT EXISTS ...
> APPEND_ONLY_SCHEMA = true, UPDATE_CACHE_FREQUENCY=900000}} is executed before
> upsert statement.
> !upsert_rate.png!
> Base table is also created with {{APPEND_ONLY_SCHEMA = true,
> UPDATE_CACHE_FREQUENCY = 900000, AUTO_PARTITION_SEQ}}
