Some annotated shell output: ```bash root@test> createtable test (1) root@test test> insert a b c d (2) root@test test> scan (3) a b:c [] d root@test test> scan -cl immediate (4) a b:c [] d root@test test> scan -cl eventual (5) root@test test> flush (6) 2022-01-28T18:58:10,693 [shell.Shell] INFO : Flush of table test initiated... root@test test> scan (7) a b:c [] d root@test test> scan -cl eventual (8) a b:c [] d ``` I create a table (1) and insert some data (2). When I run a scan (3,4) with the `immediate` consistency level, which happens to be the default, the scan uses normal code path and issues the scan command against the tablet server. Data is returned because the tablet server code path also returns data that is in the in-memory map. When I scan with the `eventual` consistency level no data is returned because the code path in the scanner only uses the data in the tablet's files. When I flush (6) the data to write a file in HDFS, the subsequent scans with `immediate` (7) and `eventual` (8) consistency level return the data. -- This is an automated message from the Apache Git Service.
