When I run:

GET \_cat/indices/tid\*

OUTPUT:

`green open tid.67a cvQK61shSBCJd8DzFSlOwA 5 1 235899 0 560.7mb 281.2mb`

I have two values for size.

My simple question is, is this size value in bits or bytes? Usually the lower case b states a bit. I cannot find any documentation that explains this.

Thanks in advance,

Jason

The size is in megabytes and the first number shows the size of primary and replica shards while the second is the size of primary shards only.
